these are the engines that ended the (stock block) Hemi chrysler reign in drag racing. Pete Robinson, Don Prudhomme,(Top fuel) Mickey Thompson (Funny Car), George Montgomery AA/GS....
The Hemi racers then had to develop high-deck aftermarket blocks and billet heads to get back on top. Most people think the Hemi was always the fuel champ. They had it, and they lost it. The current fuelers contain NO Chrysler parts. Hemis are great, but they couldn't beat these motors in modified stock form.
Robinson would come to the line, jack up the back of the car, speed up the slicks and then drop the jacks (controlled from the driver's compartment) at the green light! I saw Pete with this car, at Lions, in the summer of 1963 ~ my first year attending drag races at drag strips in Southern California ~ where I grew up; Lions, Irwindale, OCIR, Fontana, Pomona (for the Big Go West in February) and Famosa (Bakersfield) for the '65 & '67 Smokers' Meet. The NHRA eventually banned Pete's design.
@frontenginedragsterd ~ Pete Robinson was the one guy who designed a way to get around the problems of the "cammer" timing chain breaking all the time in the fuel classes by designing a gear system to replace the timing chain. With the front of the motor opened up it looked like the inside of a pocket watch exposed. Pete got the nickname in the earlier 60's when he installed hydrolic jacks inside the slicks on his 352" Ford gas dragster. (continued)
@ThePogmahome ~ Not only is Connie Kalitta still alive, he campaigns two present day top fuel cars (one driven by the Aussie, Dave Grubnic and the other by his nephew, Doug Kalitta) and a present day funny car (the yellow DHL car) driven by Jeff Arend. When drag racing was in its' REAL glory days (the 60's) John "The Mouth" Force was nowhere to be found. Some of us are sick and tired of hearing Force shooting off his mouth.
Is Kalitta still alive? I prefer John Force and his daughter(s? I know Ashley races, and I think there is another daughter who races) who are racing NOW!
You are looking at THE ultimate motor in drag racing during a large part of the 1960's; 427 cubic inches, hemispherical heads, single overhead camshafts, GMC 6-71 supercharger, Enderle 2,000 CFM rated fuel injection on nitro. I watched Connie Kalitta win Top Fuel at the 1967 Winternationals with this setup minus the Enderle injectors (Connie ran a Crower cam and Crower bug-catcher fuel injection to win the '67 title at Pomona). The achilles heel of this motor was the 3 mile long timing chain.
woow im impressed not often you see a ford running on nitro would love to see it going down the 1/4 . I was lucky enough to see a ford powered TF dragster at Pomona in 1987 it ran out of fuel on its qualifying run unfortunately.
if bill france would have let chrysler come out with that dohc and let ford run the cammer theres no tellin how high the speeds would have been and how manyguys would have been killed so thats part of the reason i think he gave ford such a hard time with the cammer cause he knew what the motor was like so thats why it ended up the boss 9 and the hemi were only allowed to run single 4 barrels.
yes ive read the sohc is a finnicky thing to tune but once its running top notch its very tough to beat no question.i agree with you on the boss having a large bore and a short stroke,they may have been better if they had the longer 3.85 460 stroke.dont forget they did there best work at 4 or 5000 rpm on the superspeedways at 200mph to.
429 Boss's are turds. I tried to do something with them, Problem is a short stroke and a piston the size of a dinner plate. by the time they rev every other engine has finished the race. Mopars are best at what they do because of their simple design. cammers were to be used for road racing which they were banned from, Chevy makes so much torque down low its crazy, But note that off shore and IHRA drags were domminated by big(700+ CID) Boss Fords for years. Tehy are all good at days end.
@598BBF CAN'T AGREE WITH YOU ANYMORE BROTHER,,YOU'VE GOT THE BIG WALLET,,AND WANT THE ULTIMATE RACE ENGINE EVER BUILT,,GET A S.O.H.C. 427 CAMMER,,GIVE IT TO JOHN KAASE,,AND GET A 2000 HORSEPOWER FIRE-BREATHING,,HEMI EATING BEAST!!! LONG LIVE HENRY FORD!!!!!!
Chrysler did NOT invent the Hemi. earliest use of the hemi was Alfa in 1918, their straight 8 DOHC injected race engine. Nice try, learn your engines. I have owned (still have 2) SOHC's, H426's,H396's, KB522's and ZL1's(yes the all alum 427 ones) by far the nastiest one is the SOHC,They will blow the other motors away but will make you crazy tuning them, Ed Pink was the master of them. Why do you think Mopar and GM made sure they were outlawed? The Indian Hemi was a runner
@Race62hud Your right,Chrysler didn,t invent the Hemi,but they perfected it....As far as I know the first car engine to use the hemispherical combustion chamber was the 1904 Welch 4 cylinder car engine...Cars like Stutz.,Duesenburgs also ran hemi type engines....Chrysler made tank and aircraft engines during ww2 experimenting with different head configurations....turned out the Hemi set up was the best for developing power
@Race62hud "Why do you think Mopar and GM made sure they (427 Cammers) were outlawed?"
- Apart from reading about it in "Super Ford" mag - You tell us. In my research Chrysler had it's version of the Cammer in the final stages of R&D which they termed The A-925 DOHC - they dropped it when Nascar outlawed the 427 SOHC.
The biggest drawback of the 426 Hemi IS the ex long travel of the rocker arms. Chrysler's Race Division knew that could be solved through the use of Double Over Head Cams >
and whenever american muscle car does a dyno test of a cammer thats been modified ill bet it puts out more than 1200 horsepower and 1400 foot pounds of toeque too.
and thats your opinion fine whatever so be it.if you knew how to read anything i wrote out in the last 5 days youd know what happened with ford engines.wake up and smell the coffee buddy.
@74rockon thats your opinion mate....but opinions are like arseholes,everybody,s got one....If its not because of the design,then why is it genius?....must be something....the Chrysler Hemi is the best v8 motor ever built
@68bobba "American Mussel Car" did a dyno test of Production, street engines where they took Chevy's Ford's and Mopars Hemi and gave their actual HP #'s
The Holmon & Moody FE Series Ford 427 (Bore-4.23 3.78 stroke 11:6.1 Compression, 2 715 CFM Holly Carbs rated @ 425 HP) The results = 6500 RPM the engine generated 637 HP and 554 ft lbs of Torque. Very impressive eh. No for the 1966 426 Street Hemi. (BORE 4.25 - 3.75 Stroke - 10.25.1 Compression - 2X4 carbs - 425 HP rating) Results = 820 HP >
@68bobba >> 689 ft lbs of Torque. @ 6400 RMP. The Show I got this information from was "American Mussel Car: Bad Boys" that I recorded to VHS from Speed Network. All one had to do to go from the 13 to the 12 second bracket with a Track pack equipped Hemi Charger for example.. was the addition of a Cam and a weight loss program for the front end of the car.
- Now that's some very impressive numbers for an engine with only a 10:25.1 compression ratio.
no you got it all wrong fella,the cammer betters the hemi and the boss is better too.cammer made more power than the boss,and the boss made more power than the hemi.ive read it i dont know how many times.between me and my old man we have enough ford books to prove that fact.also,the main reason why ford never campaigned there own engine in drag racing is because they shut down there racing program in 1970.they have now only recently come out with there own drag motor again.
motor ever made in life and its been beat on more than one occasion oval or drag racing.and whatever you guys think about the pecking order i dont really give 2 shits i know which ones made the most power first through third.you yack because the cammer wasnt available to the public but we all know what happened at the drag strips where they were allowed to run.a cammer or boss can run just as fast or faster than a hemi anyway so it dont matter.dodge may have had good drivetrains but fords were
so what it doesnt matter when the 426 hemi was invented what matters is how many times from 60 to 63 ford beat dodge in nascar and how many more times it beat the hemi from 64 to 70.i realize petty drove for ford and ford won 30 races compared to dodges 24.ive got plenty to jerk off over because the fact of the matter is that ford had more victories than dodge between 1960 and 1970.and i dont give a shit if the hemi ran 60 years in racing and was the best known motor in nascar,it wasnt the only
@74rockon Temper ,Temper,young man....I never said the Chrysler Hemi was the only motor ever invented ya fool....I,m saying the Hemi is as good as the Cammer and better than the Boss,....Ford motors made more power first through 3rd huh?....As for on the dragstrip,why aren,t Top Fuel and Funny car motors based on the Cammer or the Boss 429...because the Hemi design is better
and as for the hemi having a bigger legacy in NASCAR than the fords lets just say that it very well may have done but for only 3 seasons,66,67 and 70,those were the hemis winningest years.in fords case,since the hemis showed up,64,65,68 and 69 were fords best years against the hemi and 60,61 and 63 the fords outdid the dodges as well.so you tell me who had the bigger legacy between ford and dodge in NASCAR?total ford wins in the sixties was 225 and dodge had 216.read it and weep MOPAR FREAK.
@74rockon I,m not gonna lose any sleep about 60,61 or 63 seeing as how the 426 Hemi was not invented then...As for 69 Richard Petty drove for Ford that year,instead of Plymouth and he was part of the reason Ford did so well that year(won 10 races I believe)....So you haven,t got too much to jerk off over....The 426 Hemi is still the most well known motor used in Nascar racing
so really,is the hemi a close second or is the boss a close second to the almighty cammer?it depends on who you talk to i guess and it depends on which one makes the most power when its modified to its upmost potential too.
@68bobba Cammer 1st? A close 2nd behind the 1968 Hemi Darts and Cuda's maybe but not 1st. The reasons for it is 1) The 1968 Hemi Darts and Cuda'a were/are 10 second 120+ MPH factory tuned, quarter mile beasts which could be further refined by their owners to hit mid 8 seconds mark. 2) Cammers were not available to the general pubic, so to compare them to toned down 10:5.1 compression street Hemi's would be like comparing a 60's Chevy 409 to a 70 model LS-6 454. 3) Performance/replacement parts.
@meanmopar426 Your probably right(I hope 74rockon is reading this)...I haven,t read too much info on the race Hemis HP,torque etc,....those 68Hemi Darts and Cudas sure were scary pieces of machinery....It just goes to prove Chrysler made the best drive trains
8:264 @ 160.08 MPH in the quarter mile with a full bodied 60's era Mopar. Now that's pushing some wind. Just think what it would have been if Chrysler etc had pushed aerodynamic body designs back then. Nah, then the cars wouldn't have been as muscular looking as the engines.
any tenths of a second seperating the trio.so no one car is gonna flat out kill another in the quarter mile im afraid to say.also,once you start to modify or alter anything in any way then its a whole nother ball of wax,but im not getting into that because thats just to see whos got the biggest cock by the end of the day so who really cares.
and forth all damn day long if you want to,but since some hemis are faster and some hemis are slower than the boss,which i have just looked at now,whats the point really.the best time i found for the boss 9 was a 13.60 at 106 with a 3.91 rear gear and the best hemi was a 69 charger 500 with a 13.50 at 109.5 with a 4 speed and 4.10 rear gear.slowest hemi against the boss was a 66 satellite with a 13.81 at 104 with 4 speed and 3.54 rear gear.so they are all within 6 mph of each other and hardly
and the right rear end gears look out cause they will move with authority guaranteed.stock,at the end of the quarter,is when the boss really turned on.those huge ports and valves really moved alot of fuel and air once the rpms passed 4,000 rpm.so in reality its damn near the same as a hemi in that respect,except it was choked to death by the puny 4 barrel and measly cam.given this fact,the car still performed quite admirably on the street and the quarter mile.now we can throw stupid numbers back
to start with,ford built its boss 429 to run on the street and if you would have read about what i said about ford not wanting to run its cammer,then you would maybe get the picture that this would also apply to the boss 429.also this engine was underrated so the insurance companys would let it be legal to run.they had small 735 cfm holley 4 barrels and a rather mild camshaft so no they werent gonna rip your head off anyhow.like ive said before throw on dual quads,a better cam and headers
are bored and stroked 429s and they absolutely fly for a heavy half ton truck.those 385 series ford big blocks,which they are named because of the 460s stroke,can really get after it when modified a bit.ford made several very good engines since its first v8 came out in 1932,probably many you have never even heard of as well.now i know this argument is over a cammer versus a hemi,but there was obviously more ford motors than a boss or a cammer that could run with a hemi.
well for the better part of the sixties yes ford ruled in NASCAR because ford went all out in whats known as there total performance program which got underway in late 61 early 62.yes you are right about the 428 cj and scj equipped with those heads.there was three different versions of the 429 wedge head motors,the thunderjet 429,the cobra jet 429 and super cobra jet 429 which was a real strong performer.i have 2 buddys that have built up mid seventies ford half tons with 460 big blocks which
and put a cammer in any ford i dont care what it is and that hemis toast.read that too.proven fact:1970 mercury cyclone spoiler 2 with a 429 super cobra jet with a drag pack option ATE a 69 roadrunner with a 440 for lunch on a hi way in saskatchewan a few years ago.i know the guy that owned the mercury and he aint no bullshitter.the guy that was with him owned a 1970 ford torino with the same set up and ATE everything he went up against.went for a ride in that ford and it was NUTS.
just give me one more day and ill find numbers on both hemi cars and boss 429s.i have enough material layin around that im sure not EVERY SINGLE SOLITARY HEMI DODGE EVER MADE ANNIHALATED A BOSS 429 FROM THE FACTORY.stick a nice cam and dual quads on a bossand that hemi doesnt have a prayer.ive read that more than once too buddy.GOODNIGHT.
@74rockon here are some numbers for you...1969 Hemi Charger...0-60..5.7sec...400m..13.48@109mph...1969 Hemi Roadrunner...0-60..5.3sec...400m..13.55@105mph...1969 Hemi Barracuda..0-60..5.5sec...400m..13.4@106mph...1969 Boss429 Mustang...0-60..6.8sec...400m...14.0@103mph
getting the job done so they come out with the charger daytonas.it would be a while before those cars would be legal but it was clear an all out aerodynamic war was on.by the end of 69,ford won the manufacturers championship,DAVID PEARSON repeated as drivers champiopn,and in all FORDS took 26 wins,4 more than DODGE..
cale was first at 189.222,petty second with a highly modified car at 189.055 and was the ONLY mopar that could keep up with the fords and the next fastest MOPAR was AL UNSER at 183.525.the finish was enough to make NASCAR give in and let the MOPAR CRY BABIES run dual 4 barels.1969m saw the introduction of the talladega with boss 429 engine which wasnt allowed to run at the very beginning yet.also the charger 500 came along.they now also had to run single 4 barrels.the charger 500 wasnt
then in 1968 FORD had developed the TORINO fastback body to house the BOSS 429.they still werent allowed to run the 429 so they still used the 427.there wasnt a whole lot to worry about as CHRYSLER wasnt doing much with the hemi stating that they were obsolete and that it needed the second 4 barrel carb that foed got.the fastbacks shape proved an advantage right from the start at DAYTONA as they ran in the 190 mph range,still with only the 427 tunnel ports.when it came to official timing
with dodge charger driver LEE ROY YARBROUGH taking the first contest and FRED LORENZEN taking the second in a ford.however,the 500 turned out to be an all ford show with ANDRETTI firs and LORENZEN second giving HOLMAN AND MOODY a 1,2 finish.the next superspeedway race was ATLANTA on april 2.CALE YARBOROUGH gave ford its third major win of the young season in the WOOD BROTHERS car with DICK HUTCHERSON backing it up.CHRYSLER threatened to withdraw altogether and tried a boycott of the race.
intake with dual 4 barrels was allowed to run.the result was a very free breathing 427.CHRYSLER,struggling with last years engineering and a limited budget was furious.the blood was boiling whan they heard why NASCAR allowed fords new set up to run.if NASCAR made ford switch back to its old heads,the intake wouldnt fit.so,as a result,the combo was allowed.once the fords got sorted out,USAC champion MARIO ANDRETTI turned laps in the 182 mph range.the 100 mile preliminary contest had mixed results
@74rockon Are you going to keep this up until the 1969 season mate?.....You rated the boss 429 ahead of the 426 Hemi....yet the factory Hemi cars out performed the factory Mustang...it looks like the Boss 429 was only good in race cars like the Torinos....like I said ,Boss 429 third
horesepower in a production car.the 427 wedge would have to do for another season.more good news was coming from DAYTONA.in 63 and 64 the competition surprised ford racersd with something new,now it was fords turn.new tunnel port heads and intakes were ready to go for the 427.like chevys 427 in 63 and the hemi in 64,the new equipment ford made had not been produced in sufficient numbers to meet the rules but NASCAR looked the other way.the heads utilized huge,round intake ports.the single plane
2,4 barrels to the hemis single 4 BBL.for 67,NASCAR said it would FINALLY legalize the sohc cars for competition with no weight penalty.at roughly the same time Congress was in the process of setting up a tactic to regulate the auto industry and take a dim view on performance.FORD had tried since 64 to legalize the sohc in a fair manner but after finally having won the battle it decided not to use it in the performance war for fear of negative publicity of offering an engine capable of over 600
that meant they would weigh 4,424 pounds compared to 4,000 for the hemis.this was unacceptable and on april 15 HENRY FORD THE SECOND announced that they were withdrawing from racing.parallel to what happened a year prior,was a july reconsideration for a return.ford announced it would be back on a limited scale.late in the season factory FAIRLANES were running on equal terms with the hemis.not all the credit can go to the switch to the FAIRLANE,however a rules change permitted fords 427 to run
FORD then again made another attempt to get the sohc legalized but NASCAR said it wasnt a production engine yet.FORD said it was a standard over the counter item priced at $1,963.to make FORDS case weaker,MOPAR was now offering the hemi in its street cars,like the satellites,chargers and coronets.finally after an appeal to the A.C.C.U.S,the sohc was declared legal for installation in galaxies.only problem was a penalty of 1 pound per cubic inch was assessed against the sohc cars.
@74rockon You didn,t answer my question about the1969 boss 429 Mustang and the Hemi Chargers,Cudas and Roadrunners.....Which performed better out of the showroom?....The Chrysler cars thats who....
NASCAR produced partial settlement by july.NASCAR agreed to re evaluate the SOHC for the 66 season,let the hemis run in smaller 65 belvederes and coronets,on tracks a mile and less,and the newly introduced full sized plymouth furys and dodge polaras on tracks longer than a mile.also imposed was a 9.36pound per cubic inch weight penalty to the 427 fords which would then have to weigh about 4,000 pounds.CHRYSLER then agreed to return for the rest of the 65 season for events in which it was legal.
chrysler had quit racing as well.fred lorenzen won 4 major victories for ford,including daytona.briefly NASCAR banned the hemis and the hi risers after chrysler threatened to build a dohc hemi if NASCAR allowed the ford cammer to run.NASCAR then announced a 119 inch wheelbase limit to dodge and ford for tracks longer than 1 mile and a 116 inch wheelbase for plymouths for tyracks a mile and under.this was too much for CHRYSLER and they pulled out completely.negotiations with FORD,CHRYSLER and
to 68bobba and meanmopar426,the ford 427 low,medium and hi riser and tunnel port heads wwere only used on 427s,the low riser head was used on 428 cobra jets and a 429 is an altogether different engine.and yes ford did own nascar in 64,they had 30 victories to mopars 26,look it up.in 1965 NASCAR incorporated the use of the 65 FORD front suspension for use in all of NASCARS race cars,regardless of make because it was the only front end that could stand up.also FORD took home 48 victories in 65.
@74rockon Ford ruled Nascar strips in the mid 60's. Please show where I even hinted otherwise. Also, look back over my posts. I mentioned the 427, 428, (Cobra & Super Cobra Jet) - Yes, the Boss 429 was "an altogether different motor" - But, correct me if I am wrong.. Wasn't there a Ford 429 Wedge motor as well?
My user account may read "meanmopar426" but I am a Ford fanatic as well. In fact, this day and age I want buy a Chrysler product unless it was made before 1989.
that i would love to see because i know what power the ford makes.it would have to be a pretty god damn good hemi to match or better the ford i say.and as for the hemi being a better design than the ford try taking a look at a cammer torn down and some horsepower and torque numbers.hemi is third next to the boss 429 and 427 cammer.nuff said.
@74rockon The Hemi is a pretty good engine....Where are you getting these hp and torque numbers from mate?...A factory stock motor or a worked one?....Compare a factory 426 Charger or Barracuda to factory Boss 429 Mustang....Which had the better performance?.....As for the Cammer,it was a glorified crate motor(very powerful one albeit) which never came out in a production car....The Chrysler Hemi is a close 2nd ,not 3rd
so that chrysler and gm didnt go and whine to nascar that the fords were gonna kill em out there.so in 1966 nascar penalized ford 1 pound per cubic inch for the cammer cars and that was the onl;y way that they would let them run.so ford said like hell you are so then they developed whats known as the most feared pushrod engine ever,the 427 medium riser.they took care of chryslers then trust me.and you say that if chrysler made a hemi cammer that it would have kicked the fords arse?
@74rockon What the hell is a medium riser?....is that half a horn you get in the morning?....If I remember correctly 1966 and 67 Nascar drivers Championship was won by a Chrysler Hemi powered cars(Petty won in 67)..doesn,t look like Ford took care of the Hemi mate....Ford didn,t own Nascar in 64 either....you should check your history....The Chrysler Hemi left a bigger legacy than either the Cammer or the Boss429...
@68bobba Low, medium and high-riser was the description given to Fords 427, 428, 429 etc big block head designs. In Mopars we often do the same with a set's of 440, 413, *426 (Excluding Hemi) Wedge, Max Wedge and six pack stock head designs. It has to do with air/fuel/exhaust flow openings, entry and exit angles & yes, Piston clearances and valve sizing in untouched stock heads. for the poor men in racing, they had to use the cars as grocery getters as well, so the right heads salvaged >
@meanmopar426 Good to hear from a fellow Mopar fan....Thanks for the info,I,ve never heard of it before...ford fans should be thankful Chrysler created the 426 Hemi...if it wasn,t for that there would be no Cammer or Boss 429....think about it.....
@68bobba > from a wrecked car, and perhaps a Cam and Carb correctly tuned could add some cheaply priced power to an otherwise stock 440 and give the man increased bragging rights on the street or strip.
Wanna make this all simple?? Mopar owns the trademark rights to the word HEMI, however, nobody owns the exclusive right to make engines that have hemispherical combustion chambers. my Mitsubishi Eclipse has a 4G63 and it is by definition a hemi. simple enough?
Yeah, and you're gonna tell me that the racers were taking those Mopars right off the assembly line and slappin' 'em into a dragster, YEAH, RIGHT!!!!!
Bullshit, It was never a production engine. Here is an exerpt from wikipedia. "These engines were essentially hand-built with racing in mind. Combustion chambers were fully machined to reduce variability." And "Ford sold them via the parts counter, the single four-barrel model as part C6AE-6007-363S, the dual carburetor model as part C6AE-6007-359J for $2350.00 (as of October, 1968). " Therefore, it was never a production engine..
@Duster34072 They were sold as complete engines and allowed to run in factory competition drag racing. It was the most powerful naturally aspirated factory motor ever made then or now.
@Duster34072 While these heads were sold as parts it is also quite common knowledge that they were sold as complete "crate" engines. Don't believe everything you read on Wikipedia
@pinz32 what you all are missing is that this really was not a "production" engine as it really never came in any car from the factory. The Hemi came in many cars and even in race tune in Darts and 'Cudas in the late 60's (68-69). My real point was that had they let Ford and Chrysler alone, you would have seen some interesting things.
@pinz32 In fact, they were both sanctioned out by NASCAR . My frustration is that some on here discount the "D" Hemi heads for the Hemi as not production, (they were in fact prototypes) but call the Cammer production to brag Ford as better. If you are gonna call one non production, call the other one also. BTW everybody, I am using the "experts" definition of what is considered production. Lastly, I may have cited Wikipedia, but it is not the only source I used to answer to this topic.
17 people dont have what it takes to drive it becauce if they f up and blow the clutch they will loose a foot or there nuts or life. i ll would driive it ceep it runing from 1 motor head 2 anthoer. I love it
17 people dont have what it takes to drive it becauce if they f up and blow the clutch they will loose a foot or there nuts or life. i ll would driive it ceep it runing from 1 motor head anthoer. I love it
And the cammer never made it into production per se. But you miss the real point which was that they all stopped development as they all felt the pressure. And as far as drag racing goes, all of the top fuel and funny cars use a varient based on the Chrysler Hemi
@Duster34072 Check the 1966 Top Fuel stats...Connie Kalitta and Don Prudohm both in 427 Cammers bested the Mopar Hemi in 1966...The Hemi got more attention because it was already in production for the '67 models....There were only 30 Ford Cammers built when NASCAR blew the whistle...What few were built were handed off to drag racers. Hemis are a dime a dozen compared to the FORD Cammer!!! Take your HEMI and rotate it and bend a few pushrods/valves while doing it!!!!
it was banned from nascar becuase it was to advanced for its time it would smoke anything and everything on the track leaving absolutly no compatition. this engine is Not a (HEMI) it has hemispherical head to increase combustion but was and will never be called a hemi
@ZildjianDrummerRanck Or it Was banned from NASCAR because it was faster than the Chrysler Hemi. Until recently GM owned NASCAR, and until the Cammer came out they had hoped to develop a NASCAR winning engine. Mickey Thompson had experimented with a pontiac engine with modified Chrysler Hemi heads. Who do you think paid for that? The hemi and the cammer were faster than anything GM could come up with...so the big blocks in NASCAR were outlawed and small blocks still "rule".
yes it was banned from being way faster than the chrysler hemi. but the 427 never got to officialy race any becuase of it being to powerful for the new regulations.
yes the hemi and the cammer were faster than anything GM could come up with
and after they were outlawed ford put the cammer in "top fuel" dragster racing
now days fully super charged the 427 cammer has roughly 8,000 horse power in the 1/8th mile track
@ZildjianDrummerRanck Yeah, don't fall for the excuse that it was banned because it was faster than the Hemi. Chrysler was feeling its own pressure. Chrysler was working on a new "D Series" head in 1969-70 that never made it to production since NASCAR went to the small blocks. On one of these heads, the D 20 Magna, the intake valves were 2.50-in with a 4.00 sq-in intake port,. The exhaust valves were 2.20-in with a 2.6 sq-in port. would have loved to see them run it off.
the original 427 SOHC(sock) cammer, came out in 1965 when chrysler's hemi engines were destroying competition so ford secretly developed the cammmer. off the factory line - (stock) the cammer had 615Hp single carb and 657Hp dual carb.
Sounds like coronet493 needs to go blow his coronet somewhere else and quit blowing smoke up everybody's ass here. He must not even have a Mopar because he can't even spell it?
Ford, Mopar, both hemi's, I happen to own 2 of these. one is the nascar model still NOS crated and my fuelly, Pink, HM heads, intake , 8/71 blower. I have also ran Mopars and Rats, they are all good. Nothing looks or sounds like a Ford but dont knock the others. The mopars were 425 but actually closer to 575 , L78's closer to 510 and sohcs came out of the crate at 675. But sohcs were crate motors remember. only 12 actual Ford production race cars were ever fitted vwith them and never run.
@Race62hud So you know these HEMI's it seems. how much horsepower to you figure this guy is making with his SOHC hemi? I figure 2000 or so. Would that be right?
the 427 sohc cammer is not a (HEMI) it has hemispherical heads to increase combustion but it was and never will be called a hemi.
stock the 427 sohc would have 657Hp dual carb. depending on the racing fuel, blower and supercharger he could be runing at 1,200Hp maby 1,300Hp at most
@Race62hud Interesting. It's my understanding these cammer motors debuted in some Nascar teams at Daytona in 1966 or 67. Ford's took the top 5 positions at the end of the race and Nascar immediately banned the motor from the series. Any truth to that?
@Machi74005 They banned the boss 429. I know that. I think that they wouldn't let the SOHC run because of the OHC. This motor tore the chrysler hemi a new one.
@Race62hud Horsepower TV did a few shows on "muscle car" motors of the day. The race hemi they tested made over 800 hp. The production Ford FE WEDGE made 679 hp so don't believe the "675" figure for the SOHC. The chevy 409/425 actually made 425, so you know the rat motors of the day made a lot more than that. Interesting series. Horsepower ratings of the day were bald-faced lies by all manufacturers. Doesn't pay to underestimate the competition.
I've only just read the last page of comments - frankly can't believe what I'm reading..one guy saying SOHC cammers are shit, arguing against another guy saying 426 hemi's are shit. WHAT?? They are BOTH awesome motors - don't get ur GM /Ford/ Chrysler stupid arguments going against these two motors, its just retarded...
and justn as a reminder,next time you bend over,kiss your ass goodbye cause that cammer would have eaten your hemi mopar for breaskfast,lunch,dinner and dessert.
@74rockon Ford couldn,t make a pushrod engine to match the Chrysler Hemi ...so they had to make one with a single overhead cam....ever wonder what a Chrysler Hemi with a SOHC would have gone like?...It would have kicked the Fords Arse.....The Chrysler Hemi was still a better designed engine...
@68bobba what?ford couldnt make a push rod engine to match the hemi?maybe you should take a history lesson as you clearly need and grab a copy of the book fearsome fords.it explains everything in there.dont worry my friend,ford wasnt gonna lay down to chrysler mark my words.the reason why ford developed the cammerwas to counteract chryslers all out nascar attack in 1964 because ford owned nascar in 1963 and 64 as well.as soon as nascar saw how the fords were gonna run they put out the red flag
the sanctioning bodies changed for gm and mopar cause they wwere all suckin the hine tit that the ford was gonna pulverize them.and you say they failed in drag racing and or top fuel?check out the cammers racing pedigree sometime.failed my ass.and yesd there may be a few cammers in museums but ill guarantee ya that ive seen more in race cars and street driven cars in just about any ford built.
hey i dont dry stroke myself you mopar freak just to let ya know.and this so called futile attempt that ford made with the cammer is very far from futile.hmmmmm lets see 616 horsepower with dual quads?and what was a hemi?oh thats right only 425.peanuts compared to the mighty ford,my friend.and as for configuration as you call it,all a hemi is is hemi heads bolted to a wedge block,no different than the ford.and im sorry to say but ford didnt change any rules.
And what rules the NHRA today? Oh yeah. it's a 500 CID FORD! FORD Funny cars! It's the same old shit with the Government motors crowd @ GM & Mopar. Ford smokes 'em they whine and cry and threaten to leave so the regulating bodies give in. It's OK, we all KNOW that the ONLY INDEPENDANT car company in America is the BEST. FORD.
Nascar banned both the cammer AND the hemi,not just the cammer....they eventually let the Hemi race again because crowd numbers dropped.....As for the cammer being the best ....there,s a lot more Hemis getting around than cammers
absolutely the most powerful engine to ever come out of detroit.no chevy or mopar could even come close to this baby,they never had a hope.i like to call this engine the annihalator.
That car is Jim Green's beautiful dragster...Pretty sure that is Jim himself babysitting things as he steps around the car numerous times....tweaking and twiddling
@redenius If the blocks of the Cammer had been stronger, they'd still be kicking the crap outa Chryslers.. Not enough development time on them. All it needed was a beefier block, thicker and replaceable cylinder sleeves, and definitely aluminum construction, maybe a belt drive to get rid of that 6ft long timing chain. Believe me, once you hear one, nothing else comes close.
@65Cyclone It wasn't a factor of development time that killed the Cammer it was the fact that it was made for competition and back then it was mainly NASCAR they were aiming at but Chrysler whined and complained like a bitch and NASCAR banned the Cammer because their fucking sellouts and what other lame regressive excuse they could come up with. So that was the end of that, it wasn't economical for them to develop further into this money pit if they weren't able to race it.
This might sound very naive since i'am not that experienced with V8s or engines overall, but for performance, can you have a supercharger to lower rews and have twin turboes that starts to work at a certein RPM-level, so that you can get power over the whole rpm-range? Just a curius thought , i dont like turboes but it's just a curius thought :/
It used to be when two-stroke diesels were popular, anyway. I know the Detroits will not run without a blower to push exhaust out of the cylinders and replace it with fresh air. The non-turbo versions of those engines are grouped in the naturally-aspirated category because the blower provides little, if any boost.
Other way around; turbos are more efficient than Rootes blowers, but the blower has better off-idle boost response and makes for a flatter torque curve.
@OzzInter It might be possible for an engine with a crank driven centrifugal supercharger to run without it turning, but not one with a positive displacement roots style blower as this engine has. Just 'cause Mel Gibson did it in Road Warrior doesn't mean it will work in real life.
I watched Connie Kalitta win Top Fuel @ the 1967 Winternationals with one of these 427 SOHC Ford motors. I also saw "Sneaky" Pete Robinson killed @ the 1971 Winternationals driving a Ford "cammer." Robinson cleverly replaced the timing chain (it musta been 10 feet long) with a series of gears (it looked like the back of an opened up pocket watch) ~ his gear drive cut down on timing chain breakage which dogged the SOHC Fords during the middle 1960's.
What a beauty! Now let's see this digger make a full pass! What's that you say? No longer legal? Can't pass modern tech? Maybe that's why I don't go to the drags anymore (:
These engines had a short life span in racing...Ford dropped their racing programs just after they appeared, next was the Boss 302 and the Boss 429 as Nascar made it illegal to run this engine...Ford was way ahead of the pack but dropped out ..dropped out of Lemans type cars also like the GT40...Ford has been and still is a fickle Muther...
these are the engines that ended the (stock block) Hemi chrysler reign in drag racing. Pete Robinson, Don Prudhomme,(Top fuel) Mickey Thompson (Funny Car), George Montgomery AA/GS....
The Hemi racers then had to develop high-deck aftermarket blocks and billet heads to get back on top. Most people think the Hemi was always the fuel champ. They had it, and they lost it. The current fuelers contain NO Chrysler parts. Hemis are great, but they couldn't beat these motors in modified stock form.

Robinson would come to the line, jack up the back of the car, speed up the slicks and then drop the jacks (controlled from the driver's compartment) at the green light! I saw Pete with this car, at Lions, in the summer of 1963 ~ my first year attending drag races at drag strips in Southern California ~ where I grew up; Lions, Irwindale, OCIR, Fontana, Pomona (for the Big Go West in February) and Famosa (Bakersfield) for the '65 & '67 Smokers' Meet. The NHRA eventually banned Pete's design.

@frontenginedragsterd ~ Pete Robinson was the one guy who designed a way to get around the problems of the "cammer" timing chain breaking all the time in the fuel classes by designing a gear system to replace the timing chain. With the front of the motor opened up it looked like the inside of a pocket watch exposed. Pete got the nickname in the earlier 60's when he installed hydrolic jacks inside the slicks on his 352" Ford gas dragster. (continued)

@ThePogmahome ~ Not only is Connie Kalitta still alive, he campaigns two present day top fuel cars (one driven by the Aussie, Dave Grubnic and the other by his nephew, Doug Kalitta) and a present day funny car (the yellow DHL car) driven by Jeff Arend. When drag racing was in its' REAL glory days (the 60's) John "The Mouth" Force was nowhere to be found. Some of us are sick and tired of hearing Force shooting off his mouth.

You are looking at THE ultimate motor in drag racing during a large part of the 1960's; 427 cubic inches, hemispherical heads, single overhead camshafts, GMC 6-71 supercharger, Enderle 2,000 CFM rated fuel injection on nitro. I watched Connie Kalitta win Top Fuel at the 1967 Winternationals with this setup minus the Enderle injectors (Connie ran a Crower cam and Crower bug-catcher fuel injection to win the '67 title at Pomona). The achilles heel of this motor was the 3 mile long timing chain.

if bill france would have let chrysler come out with that dohc and let ford run the cammer theres no tellin how high the speeds would have been and how manyguys would have been killed so thats part of the reason i think he gave ford such a hard time with the cammer cause he knew what the motor was like so thats why it ended up the boss 9 and the hemi were only allowed to run single 4 barrels.
74rockon 11 months ago
yes ive read the sohc is a finnicky thing to tune but once its running top notch its very tough to beat no question.i agree with you on the boss having a large bore and a short stroke,they may have been better if they had the longer 3.85 460 stroke.dont forget they did there best work at 4 or 5000 rpm on the superspeedways at 200mph to.
74rockon 11 months ago
429 Boss's are turds. I tried to do something with them, Problem is a short stroke and a piston the size of a dinner plate. by the time they rev every other engine has finished the race. Mopars are best at what they do because of their simple design. cammers were to be used for road racing which they were banned from, Chevy makes so much torque down low its crazy, But note that off shore and IHRA drags were domminated by big(700+ CID) Boss Fords for years. Tehy are all good at days end.

Chrysler did NOT invent the Hemi. earliest use of the hemi was Alfa in 1918, their straight 8 DOHC injected race engine. Nice try, learn your engines. I have owned (still have 2) SOHC's, H426's,H396's, KB522's and ZL1's(yes the all alum 427 ones) by far the nastiest one is the SOHC,They will blow the other motors away but will make you crazy tuning them, Ed Pink was the master of them. Why do you think Mopar and GM made sure they were outlawed? The Indian Hemi was a runner
Race62hud 11 months ago
@Race62hud Your right,Chrysler didn,t invent the Hemi,but they perfected it....As far as I know the first car engine to use the hemispherical combustion chamber was the 1904 Welch 4 cylinder car engine...Cars like Stutz.,Duesenburgs also ran hemi type engines....Chrysler made tank and aircraft engines during ww2 experimenting with different head configurations....turned out the Hemi set up was the best for developing power
68bobba 11 months ago
@Race62hud "Why do you think Mopar and GM made sure they (427 Cammers) were outlawed?"
- Apart from reading about it in "Super Ford" mag - You tell us. In my research Chrysler had it's version of the Cammer in the final stages of R&D which they termed The A-925 DOHC - they dropped it when Nascar outlawed the 427 SOHC.
The biggest drawback of the 426 Hemi IS the ex long travel of the rocker arms. Chrysler's Race Division knew that could be solved through the use of Double Over Head Cams >

The Holmon & Moody FE Series Ford 427 (Bore-4.23 3.78 stroke 11:6.1 Compression, 2 715 CFM Holly Carbs rated @ 425 HP) The results = 6500 RPM the engine generated 637 HP and 554 ft lbs of Torque. Very impressive eh. No for the 1966 426 Street Hemi. (BORE 4.25 - 3.75 Stroke - 10.25.1 Compression - 2X4 carbs - 425 HP rating) Results = 820 HP >

@68bobba >> 689 ft lbs of Torque. @ 6400 RMP. The Show I got this information from was "American Mussel Car: Bad Boys" that I recorded to VHS from Speed Network. All one had to do to go from the 13 to the 12 second bracket with a Track pack equipped Hemi Charger for example.. was the addition of a Cam and a weight loss program for the front end of the car.

motor ever made in life and its been beat on more than one occasion oval or drag racing.and whatever you guys think about the pecking order i dont really give 2 shits i know which ones made the most power first through third.you yack because the cammer wasnt available to the public but we all know what happened at the drag strips where they were allowed to run.a cammer or boss can run just as fast or faster than a hemi anyway so it dont matter.dodge may have had good drivetrains but fords were

so what it doesnt matter when the 426 hemi was invented what matters is how many times from 60 to 63 ford beat dodge in nascar and how many more times it beat the hemi from 64 to 70.i realize petty drove for ford and ford won 30 races compared to dodges 24.ive got plenty to jerk off over because the fact of the matter is that ford had more victories than dodge between 1960 and 1970.and i dont give a shit if the hemi ran 60 years in racing and was the best known motor in nascar,it wasnt the only
74rockon 11 months ago
@74rockon Temper ,Temper,young man....I never said the Chrysler Hemi was the only motor ever invented ya fool....I,m saying the Hemi is as good as the Cammer and better than the Boss,....Ford motors made more power first through 3rd huh?....As for on the dragstrip,why aren,t Top Fuel and Funny car motors based on the Cammer or the Boss 429...because the Hemi design is better
68bobba 11 months ago
and as for the hemi having a bigger legacy in NASCAR than the fords lets just say that it very well may have done but for only 3 seasons,66,67 and 70,those were the hemis winningest years.in fords case,since the hemis showed up,64,65,68 and 69 were fords best years against the hemi and 60,61 and 63 the fords outdid the dodges as well.so you tell me who had the bigger legacy between ford and dodge in NASCAR?total ford wins in the sixties was 225 and dodge had 216.read it and weep MOPAR FREAK.
74rockon 11 months ago
@74rockon I,m not gonna lose any sleep about 60,61 or 63 seeing as how the 426 Hemi was not invented then...As for 69 Richard Petty drove for Ford that year,instead of Plymouth and he was part of the reason Ford did so well that year(won 10 races I believe)....So you haven,t got too much to jerk off over....The 426 Hemi is still the most well known motor used in Nascar racing

so really,is the hemi a close second or is the boss a close second to the almighty cammer?it depends on who you talk to i guess and it depends on which one makes the most power when its modified to its upmost potential too.

@68bobba Cammer 1st? A close 2nd behind the 1968 Hemi Darts and Cuda's maybe but not 1st. The reasons for it is 1) The 1968 Hemi Darts and Cuda'a were/are 10 second 120+ MPH factory tuned, quarter mile beasts which could be further refined by their owners to hit mid 8 seconds mark. 2) Cammers were not available to the general pubic, so to compare them to toned down 10:5.1 compression street Hemi's would be like comparing a 60's Chevy 409 to a 70 model LS-6 454. 3) Performance/replacement parts.

and forth all damn day long if you want to,but since some hemis are faster and some hemis are slower than the boss,which i have just looked at now,whats the point really.the best time i found for the boss 9 was a 13.60 at 106 with a 3.91 rear gear and the best hemi was a 69 charger 500 with a 13.50 at 109.5 with a 4 speed and 4.10 rear gear.slowest hemi against the boss was a 66 satellite with a 13.81 at 104 with 4 speed and 3.54 rear gear.so they are all within 6 mph of each other and hardly
74rockon 11 months ago
and the right rear end gears look out cause they will move with authority guaranteed.stock,at the end of the quarter,is when the boss really turned on.those huge ports and valves really moved alot of fuel and air once the rpms passed 4,000 rpm.so in reality its damn near the same as a hemi in that respect,except it was choked to death by the puny 4 barrel and measly cam.given this fact,the car still performed quite admirably on the street and the quarter mile.now we can throw stupid numbers back
74rockon 11 months ago
to start with,ford built its boss 429 to run on the street and if you would have read about what i said about ford not wanting to run its cammer,then you would maybe get the picture that this would also apply to the boss 429.also this engine was underrated so the insurance companys would let it be legal to run.they had small 735 cfm holley 4 barrels and a rather mild camshaft so no they werent gonna rip your head off anyhow.like ive said before throw on dual quads,a better cam and headers

are bored and stroked 429s and they absolutely fly for a heavy half ton truck.those 385 series ford big blocks,which they are named because of the 460s stroke,can really get after it when modified a bit.ford made several very good engines since its first v8 came out in 1932,probably many you have never even heard of as well.now i know this argument is over a cammer versus a hemi,but there was obviously more ford motors than a boss or a cammer that could run with a hemi.

well for the better part of the sixties yes ford ruled in NASCAR because ford went all out in whats known as there total performance program which got underway in late 61 early 62.yes you are right about the 428 cj and scj equipped with those heads.there was three different versions of the 429 wedge head motors,the thunderjet 429,the cobra jet 429 and super cobra jet 429 which was a real strong performer.i have 2 buddys that have built up mid seventies ford half tons with 460 big blocks which

intake with dual 4 barrels was allowed to run.the result was a very free breathing 427.CHRYSLER,struggling with last years engineering and a limited budget was furious.the blood was boiling whan they heard why NASCAR allowed fords new set up to run.if NASCAR made ford switch back to its old heads,the intake wouldnt fit.so,as a result,the combo was allowed.once the fords got sorted out,USAC champion MARIO ANDRETTI turned laps in the 182 mph range.the 100 mile preliminary contest had mixed results

horesepower in a production car.the 427 wedge would have to do for another season.more good news was coming from DAYTONA.in 63 and 64 the competition surprised ford racersd with something new,now it was fords turn.new tunnel port heads and intakes were ready to go for the 427.like chevys 427 in 63 and the hemi in 64,the new equipment ford made had not been produced in sufficient numbers to meet the rules but NASCAR looked the other way.the heads utilized huge,round intake ports.the single plane

2,4 barrels to the hemis single 4 BBL.for 67,NASCAR said it would FINALLY legalize the sohc cars for competition with no weight penalty.at roughly the same time Congress was in the process of setting up a tactic to regulate the auto industry and take a dim view on performance.FORD had tried since 64 to legalize the sohc in a fair manner but after finally having won the battle it decided not to use it in the performance war for fear of negative publicity of offering an engine capable of over 600

that meant they would weigh 4,424 pounds compared to 4,000 for the hemis.this was unacceptable and on april 15 HENRY FORD THE SECOND announced that they were withdrawing from racing.parallel to what happened a year prior,was a july reconsideration for a return.ford announced it would be back on a limited scale.late in the season factory FAIRLANES were running on equal terms with the hemis.not all the credit can go to the switch to the FAIRLANE,however a rules change permitted fords 427 to run
74rockon 11 months ago
FORD then again made another attempt to get the sohc legalized but NASCAR said it wasnt a production engine yet.FORD said it was a standard over the counter item priced at $1,963.to make FORDS case weaker,MOPAR was now offering the hemi in its street cars,like the satellites,chargers and coronets.finally after an appeal to the A.C.C.U.S,the sohc was declared legal for installation in galaxies.only problem was a penalty of 1 pound per cubic inch was assessed against the sohc cars.

NASCAR produced partial settlement by july.NASCAR agreed to re evaluate the SOHC for the 66 season,let the hemis run in smaller 65 belvederes and coronets,on tracks a mile and less,and the newly introduced full sized plymouth furys and dodge polaras on tracks longer than a mile.also imposed was a 9.36pound per cubic inch weight penalty to the 427 fords which would then have to weigh about 4,000 pounds.CHRYSLER then agreed to return for the rest of the 65 season for events in which it was legal.

chrysler had quit racing as well.fred lorenzen won 4 major victories for ford,including daytona.briefly NASCAR banned the hemis and the hi risers after chrysler threatened to build a dohc hemi if NASCAR allowed the ford cammer to run.NASCAR then announced a 119 inch wheelbase limit to dodge and ford for tracks longer than 1 mile and a 116 inch wheelbase for plymouths for tyracks a mile and under.this was too much for CHRYSLER and they pulled out completely.negotiations with FORD,CHRYSLER and

to 68bobba and meanmopar426,the ford 427 low,medium and hi riser and tunnel port heads wwere only used on 427s,the low riser head was used on 428 cobra jets and a 429 is an altogether different engine.and yes ford did own nascar in 64,they had 30 victories to mopars 26,look it up.in 1965 NASCAR incorporated the use of the 65 FORD front suspension for use in all of NASCARS race cars,regardless of make because it was the only front end that could stand up.also FORD took home 48 victories in 65.

that i would love to see because i know what power the ford makes.it would have to be a pretty god damn good hemi to match or better the ford i say.and as for the hemi being a better design than the ford try taking a look at a cammer torn down and some horsepower and torque numbers.hemi is third next to the boss 429 and 427 cammer.nuff said.

@74rockon The Hemi is a pretty good engine....Where are you getting these hp and torque numbers from mate?...A factory stock motor or a worked one?....Compare a factory 426 Charger or Barracuda to factory Boss 429 Mustang....Which had the better performance?.....As for the Cammer,it was a glorified crate motor(very powerful one albeit) which never came out in a production car....The Chrysler Hemi is a close 2nd ,not 3rd

so that chrysler and gm didnt go and whine to nascar that the fords were gonna kill em out there.so in 1966 nascar penalized ford 1 pound per cubic inch for the cammer cars and that was the onl;y way that they would let them run.so ford said like hell you are so then they developed whats known as the most feared pushrod engine ever,the 427 medium riser.they took care of chryslers then trust me.and you say that if chrysler made a hemi cammer that it would have kicked the fords arse?

@74rockon What the hell is a medium riser?....is that half a horn you get in the morning?....If I remember correctly 1966 and 67 Nascar drivers Championship was won by a Chrysler Hemi powered cars(Petty won in 67)..doesn,t look like Ford took care of the Hemi mate....Ford didn,t own Nascar in 64 either....you should check your history....The Chrysler Hemi left a bigger legacy than either the Cammer or the Boss429...
68bobba 11 months ago
@68bobba Low, medium and high-riser was the description given to Fords 427, 428, 429 etc big block head designs. In Mopars we often do the same with a set's of 440, 413, *426 (Excluding Hemi) Wedge, Max Wedge and six pack stock head designs. It has to do with air/fuel/exhaust flow openings, entry and exit angles & yes, Piston clearances and valve sizing in untouched stock heads. for the poor men in racing, they had to use the cars as grocery getters as well, so the right heads salvaged >

Bullshit, It was never a production engine. Here is an exerpt from wikipedia. "These engines were essentially hand-built with racing in mind. Combustion chambers were fully machined to reduce variability." And "Ford sold them via the parts counter, the single four-barrel model as part C6AE-6007-363S, the dual carburetor model as part C6AE-6007-359J for $2350.00 (as of October, 1968).

@pinz32 what you all are missing is that this really was not a "production" engine as it really never came in any car from the factory. The Hemi came in many cars and even in race tune in Darts and 'Cudas in the late 60's (68-69). My real point was that had they let Ford and Chrysler alone, you would have seen some interesting things.
Duster34072 1 year ago
@pinz32 In fact, they were both sanctioned out by NASCAR . My frustration is that some on here discount the "D" Hemi heads for the Hemi as not production, (they were in fact prototypes) but call the Cammer production to brag Ford as better. If you are gonna call one non production, call the other one also. BTW everybody, I am using the "experts" definition of what is considered production. Lastly, I may have cited Wikipedia, but it is not the only source I used to answer to this topic.

@Duster34072 Check the 1966 Top Fuel stats...Connie Kalitta and Don Prudohm both in 427 Cammers bested the Mopar Hemi in 1966...The Hemi got more attention because it was already in production for the '67 models....There were only 30 Ford Cammers built when NASCAR blew the whistle...What few were built were handed off to drag racers. Hemis are a dime a dozen compared to the FORD Cammer!!! Take your HEMI and rotate it and bend a few pushrods/valves while doing it!!!!

@ZildjianDrummerRanck Or it Was banned from NASCAR because it was faster than the Chrysler Hemi. Until recently GM owned NASCAR, and until the Cammer came out they had hoped to develop a NASCAR winning engine. Mickey Thompson had experimented with a pontiac engine with modified Chrysler Hemi heads. Who do you think paid for that? The hemi and the cammer were faster than anything GM could come up with...so the big blocks in NASCAR were outlawed and small blocks still "rule".

yes the hemi and the cammer were faster than anything GM could come up with
and after they were outlawed ford put the cammer in "top fuel" dragster racing

ZildjianDrummerRanck 1 year ago
@ZildjianDrummerRanck Yeah, don't fall for the excuse that it was banned because it was faster than the Hemi. Chrysler was feeling its own pressure. Chrysler was working on a new "D Series" head in 1969-70 that never made it to production since NASCAR went to the small blocks. On one of these heads, the D 20 Magna, the intake valves were 2.50-in with a 4.00 sq-in intake port,. The exhaust valves were 2.20-in with a 2.6 sq-in port. would have loved to see them run it off.

Nothing looks or sounds like a Ford but dont knock the others. The mopars were 425 but actually closer to 575 , L78's closer to 510 and sohcs came out of the crate at 675. But sohcs were crate motors remember. only 12 actual Ford production race cars were ever fitted vwith them and never run.

@Race62hud Horsepower TV did a few shows on "muscle car" motors of the day. The race hemi they tested made over 800 hp. The production Ford FE WEDGE made 679 hp so don't believe the "675" figure for the SOHC. The chevy 409/425 actually made 425, so you know the rat motors of the day made a lot more than that. Interesting series. Horsepower ratings of the day were bald-faced lies by all manufacturers. Doesn't pay to underestimate the competition.

@redenius If the blocks of the Cammer had been stronger, they'd still be kicking the crap outa Chryslers.. Not enough development time on them. All it needed was a beefier block, thicker and replaceable cylinder sleeves, and definitely aluminum construction, maybe a belt drive to get rid of that 6ft long timing chain. Believe me, once you hear one, nothing else comes close.
65Cyclone 1 year ago
@65Cyclone It wasn't a factor of development time that killed the Cammer it was the fact that it was made for competition and back then it was mainly NASCAR they were aiming at but Chrysler whined and complained like a bitch and NASCAR banned the Cammer because their fucking sellouts and what other lame regressive excuse they could come up with. So that was the end of that, it wasn't economical for them to develop further into this money pit if they weren't able to race it.

This might sound very naive since i'am not that experienced with V8s or engines overall, but for performance, can you have a supercharger to lower rews and have twin turboes that starts to work at a certein RPM-level, so that you can get power over the whole rpm-range?

@grumpyjenkins
It used to be when two-stroke diesels were popular, anyway. I know the Detroits will not run without a blower to push exhaust out of the cylinders and replace it with fresh air. The non-turbo versions of those engines are grouped in the naturally-aspirated category because the blower provides little, if any boost.

@Eddiemotor
IT has been done but a Roots blower is way more efficient than turbos at any rpm.

@dragonelectricabq
Other way around; turbos are more efficient than Rootes blowers, but the blower has better off-idle boost response and makes for a flatter torque curve.

@Eddiemotor
Yes.
Lancia Delta S4 have this configuration. but it's a 4 cylinder so 1 turbo and 1 supercharger.
michaelovitch 1 year ago
@Eddiemotor
Correct!
Superchargers are driven off the crankshaft and the one depicted in the video operates as soon as the crank pulleys turn.
It was possible to have a "blower clutch" which disengages the drive to the supercharger until needed.
Turbos are driven by exhaust gasses.
Until a certain RPM there is usually not enough pressure to make the turbo work.
Turbos, in road cars, usually have a bypass system (diverter) to stop the turbo operating unless the extra power is needed.
OzzInter 1 year ago
@OzzInter It might be possible for an engine with a crank driven centrifugal supercharger to run without it turning, but not one with a positive displacement roots style blower as this engine has. Just 'cause Mel Gibson did it in Road Warrior doesn't mean it will work in real life.

I watched Connie Kalitta win Top Fuel @ the 1967 Winternationals with one of these 427 SOHC Ford motors. I also saw "Sneaky" Pete Robinson killed @ the 1971 Winternationals driving a Ford "cammer." Robinson cleverly replaced the timing chain (it musta been 10 feet long) with a series of gears (it looked like the back of an opened up pocket watch) ~ his gear drive cut down on timing chain breakage which dogged the SOHC Fords during the middle 1960's.
