What's with all the hate for pushrods? SAM built a LSX for the LS shootout that's 7.1L and makes 1000HP all motor. That's 140HP/L at 9000rpm with pushrods. That isn't too bad for something that's supposed to be so primitive and inferior. DOHC is great and all (and expensive for what you gain) but just because an engine has 2 valves/cly and one cam doesn't make it worthless.
Pushrods are not worthless. Listen buddy, one thing in engineering is rule. No one cares how much you spend money for building engine, people only remembers the winners. Only reason why pushrod engines are cheaper than European V8 DOHC is number of produced and sold engines. GM produce more than 100,000 V8 pushrods per year, while Euros maybe 20,000 max. LS7 cost 20,000 $ in EU, but Mercedes AMG 352CUI 35,000 $. AMG produce more power and torque stock.
@2jzgtejza80 I think you need to read my comment again. I never said pushrod engines were worthless. I just gave an example of what someone did with a pushrod engine, 1000HP 140HP/L at 9000RPM, isn't too bad for any engine. Mush less a pushrod engine. Like I said, DOHC engines are great, they do tend to make more high rpm HP, but for the added cost and complexity I really don't think its worth it unless budget is not a concern. If that's the cause they DOHC may be for you.
Like I said, every design have advantages and disadvantages. You are right, but tuning of OHV design is more expensive, than stock DOHC. Many DOHC engines today produce huge power and torque (specially racing type). Tuned NA pushrods cost a lot of money, that's why people using SCs or TCs.
@2jzgtejza80 Sorry, but that's wrong. OHV engines are inherently cheaper to buy and modify (or "tune") than DOHC. in order to do a cam upgrade on a OHV I need just one cam, DOHC needs 4 (on a V8) Do a valve upgrade OHV needs 16 valves, DOHC needs 32. And the list goes on.
Many pushrod engines today produce huge power and torque (especially racing) Tuned NA DOHC engines cost a lot of money too, anytime you need to change something related to the heads you've got to spend like 3 times more.
@2BarEG more efficient...well more room for valves, yes. significantly worth more HP? not so much. If I thought adding DOHC 4V/Cly on my 400HP 350 was worth the $5000-$8000 expense I'd be all for it. Turns out I could spend half that for a blower and almost double the output so DOHC is totally not worth it in terms of HP/$.
Pushrods are retarded. If you take two identical naturally aspirated big blocks, one with DOHC heads, and one with redneck pushrods, the one with DOHC heads will make more torque, and more power, and will have the ability to rev higher (if needed). Get over it.

This thing will never see rpms past 7500. So why the fuck would you waste so much time and effort on a valve train and cylinder heads like this? On NHRA pro stock engines the needle rips past 10,300 rpm. On top alcohol past 9,500. BOTH are SINGLE CAM, PUSHROD engines. There is absofuckinglutely no way to legitimize this much extra cost and complexity unless you are running a formula one engine. period.
@BugattiFan301 Four valve per cyl. engines don't need as high octane of fuel to make equal power, they meet emission regs. easier, they use less fuel to make equal power, a well engineered 4 valver will have much less valve train stress at equal rpm and will ultimately outrev a 2 valve engine of similar geometry. The racing engines you refer to are very highly developed engines and are engineering marvels in their own right, but DOHC 4valve motors are coming, and you can't stop whats coming.
572 CUI engine with DOHC valve train produce at 7500rpm more than 100hp / liter naturally while pushrods are not even close. Ford had DOHC 1100 CUI engine all-aluminum in 1947 designed for tanks.
This engine is capable past 7500rpm with different setup of valve train. NHRA pro stock engines cost much more than this one and it's top of pushrod engineering. 10,300 rpm is useless unless you get 150hp/liter and 100 Ibs / liter
Ray Barton Racing Engines produced the same power, 1475 HP @ 7,500 RPM, with a 572 cubic inch push rod hemi superchared with a PSI screw supercharger and EFI. The engine idled at 900 RPM and run on pump 93 non lead gasoline. The engine was for a street machine
@guri131 not saying nascar is the most advanced motor sport in the world but you show me any euro v8's running 10k - 9k rpm's flat out every weekend and do it with no problems your to ignorant of what we do with push rods to see that it's still better then any thing euro's make and cheaper and last forever
@dankebuddha i love American cars and American cars only but don't be ignorant. F1 cars are limited at something like 20,000rpm. I like push rod motors but realize that there is a place for technology as well
@natebrod up to 18k and running all day long at 9k are 2 different thing's also getting a small displacement v 10 to do that is relatively easy compared to getting a big displacement v8 to do it also the nascar motors dont need to be rebuilt after every run either keep in mind 9k is not the max rpm they were running 11k til nascar said they were too fast and limited them to 9k rpms which allowed Toyota to compete in nascar now
Hey genius tell me how Toyota/Lexus developed their V10 and how Dodge did and you will see why they are vastly different.
Here's a hint, truck motor and and a ground up built motor. Even if the "world" has progressed, why are GM's LSx series motors extremely populars swaps while still using old technology pushrods? They are easy to maintain and build.
@undeadkillers The question was which motors are superior.
Google " Ward's 10 best engines" and check for yourself how many American engines have figured in the yearly lists.
In 2011 ,there are three American engines in the list out of Ten . Ford's Coyote 50 V8 , Chrysler's Pentastar V6, GM's Twin Port 1.4L and ALL THREE are DOHC motors. Need i say more?
GM 4th generation of engines are popular because: They are new design all-aluminum alloy, means lighter, upgraded EFI, ECU electronic control, much higher quality parts (better materials), easy to maintain (if you are in US), easy to buy (if you are in US), and small taxes on displacement (if you are in US). US IS NOT ONLY COUNTRY IN THE FUCKIN' WORLD. Europeans rather buy a V8 Toyota, BMW, or any other swap, because maintaining these engines are cheaper in EU than LS series.
This looks like the Eagle 750 motor..... a clean sheet design that was way ahead of its time. Just checked the site, yep it is that bad boy. Glad to see that it is comming back as it all but disappeared except for those that were digging to find it. As much as it was usually shown with a blower back in the day, I always imagined it with a set of water jacketed turbos.... and in my boat of course. Sweet motor, but it always was.
I remember when Kenny Bernstein ran FunnyCar back in the 90's with an DOHC 4 valve/cyl McGee(?)with screw compressors for blowers. He kept blowing them up for some reason and NHRA put a stop to that experiment. What happened?? I thought DOHC's and screw compressors were more efficient. I guess the "old school" designs(Detroit Diesel blowers(1936) and push rod Hemis(1953)) can take the punishment the Nitro dishes out.
Superchargers are gay...buy some turbos to make real power...1400 on pump gas on a engine dyno??...i have a twin turbo carburated 548 bbc that makes 1210 to the wheels in a 4x4 truck lol this motor is weak...look it up twin turbo sand truck!!! super chargers constantly build boost becuase there belt driven...not reliable gay old news
@LiLJankie I’m really surprised that someone who claims to have built a 1000HP+ twin turbo big block refers to roots superchargers as “gay.” I’d expect that from some teenager driving a 120HP Civic with no concept of supercharging but not someone with supposed experience. I guess you’re unaware of the fact that the most powerful automobile racing engine’s in the world use roots superchargers. And roots have certain advantages over turbos. It depends on application.
Now what exactly makes this inefficient in any way?
Because the have probably has a volumetric efficiency somewhere around 98-99% up to 10,000 revs. It's either a twin screw or roots charger, and those are good ways to make power and the twin screw isn't a horrible parasite like some make it out to me.
I'm a turbo guy, but with this set up you don't have to complain about any turbo lag.
I'd like to see what engine you'd call good sounding and efficient.
@Evancarrick12 NRE...1000+ hp twin turbo STREET cars...you build a turbo motor right with turbo size you wont have turbo lag...i have a twin turbo big block that makes 1210wheel hp and has zero turbo lag with twin 76mm turbos
I get that not all turbo set ups are going to have lag.. But we definitely run into lag with an itty bitty I-4 turning say, a gt-42. A huge turbo that will push 30lbs into a two litre engine past 10,000RPM.. But it won't make the boost til around 4k.. A big block however, will always be pushing enough air to have two of the moving by around 2k, virtually eliminating lag.. I'm in the new era, I don't use the term "no replacement for displacement."
@Evancarrick12 lol dude, the “new era” isn’t much different from the old. We’re still using the same basic engine they were using 100 year ago. And in all that time there never has been a replacement for displacement. Another way of putting it is anything you can do to a small engine, I can do to a bigger one and make more power. Simple physics.
I'm just simply saying that anyone can put a new air filter on a big block and bolt on a bigger carb.. But it takes some serious skill to build a two liter engine to run with the big boys.
@Evancarrick12 Um...that's a pretty patronizing remark to anyone who races a big block. That would be like someone saying all you're doing is slapping a giant turbo on a dinky engine, reving the piss out of it and crossing your fingers it doesn't blow up. I think you'd be the first to say there's a little more to it than that.
An engine makes power based on how much a/f it can burn. If I can make my dinky ass little 4g63 burn as much, and as reliably, as your big block, then yea, I'd say it's a bit more difficult.
More head pressure, more rod pressure, more crank pressure.Same amount of heat in much less volume.
It's not just about revving the piss out of something, it's about developing a working relationship between all the parts..
@Evancarrick12 Did you even read my comment? First off I didn't even say I had a big block I said your remark was patronizing to anybody who raced one. You actually did exactly what I said you would only what I said was a comparative example. That tells me you not thinking about what I said.
Second, could you just put the last two parts of that last comment in a folder and file it under: "Shit I Already Know."
Just looking to flame aren't you. Because this is going no where..
All you've said is that bigger is better. And that's completely true.
But there is something to be said for an engine builder that can make a reliable 1000 horse 2jz engine, and there's a reason that it isn't so impressive to have a reliable 1000 horse ls9..
@Evancarrick12 If anything YOUR comment was the inflaming one. You took a shot a people who race big blocks and your accusing me of trying to start a flame war? Lol Real nice. And usually when somebody loses a point or is shown to be wrong the first think I hear is “this is going nowhere.”
You still don't seem to be thinking about what I'm saying...oh well, I don't anticipate your next response to be any more insightful that the other 2.
@Evancarrick12 “I'm just simply saying that anyone can put a new air filter on a big block and bolt on a bigger carb.. But it takes some serious skill to build a two liter engine...”
And you don’t understand how that’s condescending toward people who race big blocks? I’d refer you back to my example doing the same thing you just did only toward people racing smaller turboed engines but I get the feeling it’d be lost on you. Its irritating talking to someone who can't keep track of what they say.
@Evancarrick12 putting a different filter and a bigger carb will net you 5-maybe 20 horse if your lucky its gonna put you no where close to 1400 hp. it takes A LOT of knowledge about engines to push out 1400 horse even out of a big block. now just because adding a NOS sticker on your ricer adds 50 horse doesn't mean it works on a big block
@Evancarrick12 oh and there still is no replacement for displacement when it comes to drag racing. you say add a turbo, i say put a turbo on the V8 and watch it kick the four bangers ass. the fastest drag cars in the world are big blocks not four bangers. and dont even say "well try to take a corner" cus hardly anyone races around corners on the street plus there are v8s and v10s that can take corners just fine
I know, there really isn't a replacement for displacement.. Because all adding a blower does is gets more air.. the plus to a larger engine is that it flows more air, so a blower in a way adds displacement, much as EGR lowers displacement. There will never be any replacement for the big block, they're great. Just that if I see a DSM smoke an F-body, I'll respect the DSM'er a bit more.
@SuperVAIK Which will make it the baddest civic there ever was lol. It's unlikely though, they'd rather get a shift knob, fake hood scoops, and engine bay vents from Autozone.
@southcountyman Uh…how? 572 4v/cly supercharged vs. (I’m assuming) 383 2v/cly (I really hope) supercharged. Doesn’t look good for you on paper unless you’ve got some special racing big inch small block. Don’t get me wrong I love small blocks, have a 350 myself, but come on, against a 572 with a blower?
@dectrone im a tool? i was done talking about the small block you stupid fuck. you said say hi to john force and i said i will he works for the family. Jesus Christ you are fucking retarded and need to learn how to fucking read and stay on topic you stupid nigger!!
that is a sick engine, all the faggots leaving messed up comments are just upset cause this can waist there hondas and subarus and even daddys amg mercedes
Awesome motor!!!!!!!!!!! But ive got a problem with all the morons saying stupiid shit! Oh it would be better if you did this or my uncle had one, or mines better, or i would rather have a diesel doing fuck knows what. It never ceases to amaze me how many fuckin idiots are walking around, i would have thought dumbasses like this would have inbred themselves out by now.
@slasherhost Who makes 573??? Or is that like Merlin, or is that some number you just pulled out of your ass???? The reason is I know that chevy makes a 572...
@dickweed101us my name is robert, im 33 and hold a uti scholarship in engine performance, a 327 chevy smallblock isnt exactly 327 inches, a 454 isnt exactly 454 inches, a 572 isnt exactly 572 inches, now get a life and show some respect,
what do you mean as pump gas? do you mean crappy american fuel barely hitting 88 octans? in this case it is quite achievement from such displacement, anyway i would prefer supercharged DIESEL v8 around 1400hp and some serious torque
OK - I just went through 25 page-downs of comments and all you fucking morons seam to want to do is bitch about thermal dynamic efficiencies and power to wieght ratios when - those HEADS ARE A FUCKING GOLDMINE !!! Don't you fools know a good thing when you see one !!! DOHC 4 VALVE 2 PLUG HEADS that fit on a 572 IDIOTS !!!! Who makes those heads and where can somebody like me get a set !!!
Totally agree with you. When u talk about an engine with that displacement - about 9,4 liters for us europeans - and the technology of a late 20 century car, all other things to discuss are simply irrelevant.
@mrnewagemotor I've learned there will always be people out there who can point out a "flaw", even if it's more of an idiotic opinion; especially on youtube. I agree 100% with your comment, these heads are probably worth as much as my motor.. insane to get 1400+hp on PUMP GAS. Much respect to this build.
Well for a start more valves in head means greater surface area therefore better breathability. Less reciprocating mass means higher revrange. The ability to dail up seperate intake & exhaust timming (really handy with turbos) without having to change cams just use degree wheels. Smoother running (if you care about it) if on the street. I looked at your profile. You should already know these things, Or are you just testing me.
I know its prob a drag engine but drag aint everything.
@blyndrotor It has nothing to do with "fear". It has to do with cost efficiency, mostly. Four times as many camshafts. Twice as many valve springs, valves, cam followers (aka "lifters" in pushrod engines), retainers, valve locks, valve seats, valve guides, valve seals, four times as many cam bearings, you get the picture. All of these components cost money. What are the measly benefits? 12.5% (at maximum) greater surface area of valve heads. Slightly reduced wear and stress on the valve train.
@blyndrotor What are the other minor benefits? Well, you can use a slightly higher compression ratio. But let's say you want to cnc port those heads. Well, that will cost you TWICE as much as it would with a 2-valve engine. And CNC porting is NOT cheap. Even though you may get ~20 psi greater Brake Mean Effective pressure with the same intake/exhaust design and profile, DOHC clearly costs WAY more than it is truly worth.
@mrnewagemotor walmart. they say they've lowered prices....32 cents now, but it will take 6 1/2 hours to check out....400 lanes, 2 open. Guy in front of you will have 213 pkgs of enema product, but will demand a price check, swearing there is a 1 cent price difference....in total.

any one know what one of these costs in estimation im curious cause the guy who builds them is a local and i havent the slightest idea of how to ask him but im curious to know the estimated price of one
people who are saying bigger engines have more horsepower potantial then smaller, are most likely always right, for the people who wanna know why heres a small lesson,
The formula for the power of an engine: combustion pressure x displacement x revolutions per second x number of cylinders x factor for 2-stroke or 4-stroke
or: P = p x 1/4 x pie x d² x s x n x z x a
p = maximum pressure during combustion
d = piston diameter
s = piston stroke
n = number of rev / s
z = number of cylinders
a = 1 for a 2-stroke and 0.5 for 4-stroke. two stroke has a power stroke every revolution, four stroke has a power stroke every 2 revolutions.
Hahaha! You're using a 206D Supercharged 572 and only getting 1400 HP?! That's laughable, and you don't need DOHC to even get twice that power. Pro Mods Get 2500+ HP From 526 Cu in. with the same supercharger. Youo must either be getting very little (+- 20 lbs) boost, which is pitiful for this particular supercharger, or you are running a very shitty valvetrain with low lift and duration. You don't fuckin need a 206D to make 20 lbs boost!
Has it never occurred to you that dragsters don't use the bullshit gasoline that all of us get at the gas station on the corner? I guess not. A username like BugattiFan301 is evidence enough of that. Full on dragsters use high octane gas that contains triethyl lead, to give the fuel the resistance to detonation that is paramount in an engine that creates such extreme cylinder pressure. We all use UNLEADED fuel, that at best, is 94 octane. 87 is the norm 85 theshit Not 110, 112, or 118 race gas.
Haha, pro mods don't use race gas, they use methanol. You don't know shit about drag racing. Admittedly, it is harder to get as much power without ruining your engine when you have low octane fuel. Also, admittedly, methanol does have an octane rating of 110+. But, still, this engine puts form WAY before function. Those cylinder heads have to cost an enormous amount of money, and you will have to pay for 4 camshafts instead of one and twice as many retainers, valve locks, and valve springs.
I never mentioned anything about Pro mod, and the type of fuel they use. My statement was general. To the point of 1400 hp being quite a stellar production for pump gas. I realize you said that Pro Mods use the same blower, and get 2500 hp with it. But then, they use methanol. Not pump gas. Just for the info, methanol carries an octane of about 119.
On top of that, the supercharger costs ten thousand dollars when you could just buy a stage four 14-71 supercharger for four. I also noticed it has a dry sump oil system. This engine is simply impractically expensive and ridiculous. The only person who would even consider buying this is somebody who knows nothing about engines and has more money than sense.
ha, you guys tear me up, you can argue all the facts and figures you like but the proof is on the track. I suggest you both take your high power cars to the nearest drag strip and race! That is what these motors are built for, not powering forums!
Now, folks, true power, it is true, but this recipe is stolen from imports, who else has been using DOHC and fuel injection and computer ignition for decades? Euro/asian cars, not american.
Now, folks, listen to this moron. 2URBO2 thinks that there is an advantage that comes with OHC vs. OHV. Does your dumbass seriously not realize that OHC's and OHV's are just a way of controlling the camshaft, and have almost nothing to do with the engine it's self?
The only difference is, a chain and gear, instead of a pushrod, which OHV engines actually do incorporate, but only as a means of controlling the pushrods.
F.I.? Who cares, there are carbureted engines making 8,000+ HP.
Now, you think OHV is cool because your cars are fitted with it, but it is not. OHV is cheap, and it is reliable because it is as old as it is uneffcient. 2 valves per cylinder is the maximum, while a dohc engine would have 3 times that. Now, in the last few decades the dohc engines have been developed more and more reliable, plus it is efficient. Just compare a 6 liter OHV V8 to a 6 liter DOHC V8. I have been on a engine repair shop, and worked for a month, so i know what im talking about.
OHV's are cool because they are simple, and they work. Why would you want to grind FOUR camshafts, when you could have far less of a parasitic loss by just spinning one camshaft, and using very light pushrods?
Why would you even want MORE valves? That is just simply more mass that has to be moved. The key to efficient power is simplicity. Why have more mass, when you can get the job done with 2 valves?
since when has a timing chain, rocker arms, and 2x.5meter long pushrods been light and simple? i like pushrod engines but saying that an overhead cam engine isnt simpler is just dumb, theres a reason the world uses ohc's and 3,4 and 5 valve heads, its called improvment
Now, there are extremely high revving, high cubic inch engines. Top Fuel dragsters for example, they sometimes rev to 9,000 RPM, and create 8,000 Horsepower.
Do you know what they use? PUSHRODS.
Pushrods may be very light, if made in cast aluminum. OHC engines are typically NOT simple.
How would you figure that a Ferrari V12 with 5 valves per cylinder is SIMPLE? That is 60 very TINY valves.
As far as I'm concerned, the most powerful dragsters use simple old OHV tech. Enough said.
ferraris and bugati 5 vaves are the minority most of europe and asia and the us may i add use 4 valve heads because it allows a central spark pug, a symetrical chamber and 4 slightly smaller valves will allow more flow than 2 bigger ones, and how long do top fuel dragsters last? you cant use something which relies on a $80,000 engine and the most volatile fuel in a car as proof. jst go ask on some forums im sure youll learn something
You're the one that needs to learn something. Any engine under 1,000 C.I.'s is going to tear it's self apart while producing 8,000 BHP.
There are daily driven 800 Horsepower 2 Valve Chevrolet Small Blocks. Just go to Nelson Racing Engine's site, or better yet, talk to someone that runs a twin turbo SBC in any GM car.
Now, 2URBO2, or should I say, kiddo. Let's learn something. 'Advanced' engines that incorporate fuel injection, and OHC designs are more for ease of road use, despite the fact that many are used in racing of many kinds.
How the fuel gets into the engine is not of importance, the factor that counts is IF you're getting the right amount of fuel and air.
Beside the point, Chevrolet has been using various types of fuel injection since the 1950's, dipshit.
Well, DOHC has been in use for a long time, and it is a reason "everyone" is using this technique, and not OHV, as americans do. But it's a reason for that, the OHV is cheap, and it is so simple that it will work dead on.... But there are disadvantages... They have easier valve floating, they cant rev as high as a OHC engine, there is more parts moving from cam to valve, so it can easily break.
Furthermore, to compare these 6.0 Liter OHC and OHV engines that you talk of, they would have to be equal to make it fair.
They would need heads with the same flow rate, the same compression, pistons, rods, and crankshafts of the same weight, they would need equally flowing intake manifolds, everything down to the intake filter would need to be equal.
THEN, maybe, just maybe, your dumbass would see that there is not THAT much of an advantage to OHC.
As mentioned above, there is something called a MULTIVALVE engine. An OHV engine doesnt have that, a OHC engine have that. More valves = better flow = better torque and horsepower ratios.
Just look at Gumpert Apollo, it's direct fuel injected audi V8 engine of only 4.2 liter has up to 800 horses. Thats almost like a F1 engine.
Honestly, who even cares about fuel injection? Fuel injection helps with straightening out A/F ratios, which may yield a whole 5 Horsepower, and 2-3 MPG's depending on the car.
Also, with the OHC vs. OHV debate. OHC's advantage comes in the upper RPM's, which is excellent for small engines, but is not a concern with large engines (6.0+ Liters).
Engines that size have no need to rev high to make power, they have a thing called TORQUE. Which is why, OHV's have been a mainstay in the U.S.
Well, there is something called multivalved engines, which OHV engines dont have. Better injection of air/fuel into the cylinder = better torque and horsepower ratios. Not only good for small engines.
That is a total assumption. So, you're saying that no 2V engine can flow as good as a 4V?
So you're saying that those Hemi engines in Top Fuel drag racing, aren't making the 8,000 BHP that they do, just because they mainly use 2V heads?
What you're not understand is, it's not the amount of valves that you have, it's what each valve flows. Intake/exhaust valves are not a one size fits all deal. You can go out and buy 2V heads that'll outflow any 4V head known to man.
why have a 5000rpm redline and 1000hp when you can have a 7000rpm redline and 1200hp on the same motor?
and fuel injection helps with performance and economy (like it matters) and atmospheric onditions, ever had fuel vaporise in your pipes, or had to use a choke in the cold?
what makes more power.... 400ft lb's at a 5k redline, or 400ft lb's at a 7k redline, the cat 797 makes 2300hp but only revs to maybe 2000rpm, if it could rev to 3000 it would be more powerful, (well ok if the torque was moved further up the rev range which in that scenario isnt useful but still the idea is correct)
400 FT.-LBS. at 7,000 RPM, of course. You're missing the main point though. The powerband characteristics. You cannot just instantly go from producing that amount of Torque at 5,000 RPM, to 7,000 RPM.
It would require massive amounts of boost, a far more radical camshaft, far stronger pistons. Most likely a different manifold, and a different E.F.I. or Carb setup. Just to get the correct flow characteristics.
The idea is correct, but not realistic at all without major improvements.
well noone said powers easy to make, the arguement is wether ohv (with valves) is better than dohc with 4, my view is dohc opens more possibilitys but you should base your engine around its intended use.
when just trying to move a car, not racing, not just barely moving but a purely usable engine a 2.0-2.4 liter 4 with dohc and a turbo making 240 hp is more than adaquate. so why would you ever need a 5.7l ohv gas guzler for the same purpose (other than refinement which is fair enough)
Why would you want only 2 Litres of displacement, or 4.2 Litres of displacement, when you can make more power with a bigger engine, naturally aspirated in most cases?
Do you know what supercharging, or turbocharging an engine does? It essentially increases it's DISPLACEMENT. More air is being displace. That's all it is, more air forced in, to increase displacement.
Now in literal terms, it is not making the engine any bigger, yet, it is actually increasing displacement.

GM LS series of engines are the best pushrod engines ever made. When GM starts producing a V8 427CUI blocks with DOHC design I'm first buyer.
GM engineers are not stupid people, they can, but they wont produce V8 DOHC because of complex valve trains and heavier heads than OHV.
DOHC or OHV, no matter, both designs have advantages and disadvantages, like everything in life.

What's with all the hate for pushrods? SAM built a LSX for the LS shootout that's 7.1L and makes 1000HP all motor. That's 140HP/L at 9000rpm with pushrods. That isn't too bad for something that's supposed to be so primitive and inferior. DOHC is great and all (and expensive for what you gain) but just because an engine has 2 valves/cly and one cam doesn't make it worthless.

@Warblade118
Pushrods are not worthless. Listen buddy, one thing in engineering is rule. No one cares how much you spend money for building engine, people only remembers the winners. Only reason why pushrod engines are cheaper than European V8 DOHC is number of produced and sold engines. GM produce more than 100,000 V8 pushrods per year, while Euros maybe 20,000 max. LS7 cost 20,000 $ in EU, but Mercedes AMG 352CUI 35,000 $. AMG produce more power and torque stock.

@2jzgtejza80 I think you need to read my comment again. I never said pushrod engines were worthless. I just gave an example of what someone did with a pushrod engine, 1000HP 140HP/L at 9000RPM, isn't too bad for any engine. Mush less a pushrod engine. Like I said, DOHC engines are great, they do tend to make more high rpm HP, but for the added cost and complexity I really don't think its worth it unless budget is not a concern. If that's the cause they DOHC may be for you.
Warblade118 10 months ago
@Warblade118
Like I said, every design have advantages and disadvantages. You are right, but tuning of OHV design is more expensive, than stock DOHC. Many DOHC engines today produce huge power and torque (specially racing type). Tuned NA pushrods cost a lot of money, that's why people using SCs or TCs.
2jzgtejza80 10 months ago
@2jzgtejza80 Sorry, but that's wrong. OHV engines are inherently cheaper to buy and modify (or "tune") than DOHC. in order to do a cam upgrade on a OHV I need just one cam, DOHC needs 4 (on a V8) Do a valve upgrade OHV needs 16 valves, DOHC needs 32. And the list goes on.
Many pushrod engines today produce huge power and torque (especially racing) Tuned NA DOHC engines cost a lot of money too, anytime you need to change something related to the heads you've got to spend like 3 times more.

@Warblade118 well worth it...so much more efficient.
2BarEG 8 months ago
@2BarEG more efficient...well more room for valves, yes. significantly worth more HP? not so much. If I thought adding DOHC 4V/Cly on my 400HP 350 was worth the $5000-$8000 expense I'd be all for it. Turns out I could spend half that for a blower and almost double the output so DOHC is totally not worth it in terms of HP/$.

Pushrods are retarded. If you take two identical naturally aspirated big blocks, one with DOHC heads, and one with redneck pushrods, the one with DOHC heads will make more torque, and more power, and will have the ability to rev higher (if needed). Get over it.

This thing will never see rpms past 7500. So why the fuck would you waste so much time and effort on a valve train and cylinder heads like this? On NHRA pro stock engines the needle rips past 10,300 rpm. On top alcohol past 9,500. BOTH are SINGLE CAM, PUSHROD engines. There is absofuckinglutely no way to legitimize this much extra cost and complexity unless you are running a formula one engine. period.
BugattiFan301 1 year ago
@BugattiFan301 Four valve per cyl. engines don't need as high octane of fuel to make equal power, they meet emission regs. easier, they use less fuel to make equal power, a well engineered 4 valver will have much less valve train stress at equal rpm and will ultimately outrev a 2 valve engine of similar geometry. The racing engines you refer to are very highly developed engines and are engineering marvels in their own right, but DOHC 4valve motors are coming, and you can't stop whats coming.

572 CUI engine with DOHC valve train produce at 7500rpm more than 100hp / liter naturally while pushrods are not even close. Ford had DOHC 1100 CUI engine all-aluminum in 1947 designed for tanks.
This engine is capable past 7500rpm with different setup of valve train. NHRA pro stock engines cost much more than this one and it's top of pushrod engineering. 10,300 rpm is useless unless you get 150hp/liter and 100 Ibs / liter

Hey genius tell me how Toyota/Lexus developed their V10 and how Dodge did and you will see why they are vastly different.
Here's a hint, truck motor and and a ground up built motor. Even if the "world" has progressed, why are GM's LSx series motors extremely populars swaps while still using old technology pushrods? They are easy to maintain and build.

GM 4th generation of engines are popular because: They are new design all-aluminum alloy, means lighter, upgraded EFI, ECU electronic control, much higher quality parts (better materials), easy to maintain (if you are in US), easy to buy (if you are in US), and small taxes on displacement (if you are in US). US IS NOT ONLY COUNTRY IN THE FUCKIN' WORLD. Europeans rather buy a V8 Toyota, BMW, or any other swap, because maintaining these engines are cheaper in EU than LS series.

This looks like the Eagle 750 motor..... a clean sheet design that was way ahead of its time. Just checked the site, yep it is that bad boy. Glad to see that it is comming back as it all but disappeared except for those that were digging to find it. As much as it was usually shown with a blower back in the day, I always imagined it with a set of water jacketed turbos.... and in my boat of course. Sweet motor, but it always was.

I remember when Kenny Bernstein ran FunnyCar back in the 90's with an DOHC 4 valve/cyl McGee(?)with screw compressors for blowers. He kept blowing them up for some reason and NHRA put a stop to that experiment. What happened?? I thought DOHC's and screw compressors were more efficient. I guess the "old school" designs(Detroit Diesel blowers(1936) and push rod Hemis(1953)) can take the punishment the Nitro dishes out.

@LiLJankie I’m really surprised that someone who claims to have built a 1000HP+ twin turbo big block refers to roots superchargers as “gay.” I’d expect that from some teenager driving a 120HP Civic with no concept of supercharging but not someone with supposed experience. I guess you’re unaware of the fact that the most powerful automobile racing engine’s in the world use roots superchargers. And roots have certain advantages over turbos. It depends on application.

Now what exactly makes this inefficient in any way?
Because the have probably has a volumetric efficiency somewhere around 98-99% up to 10,000 revs. It's either a twin screw or roots charger, and those are good ways to make power and the twin screw isn't a horrible parasite like some make it out to me.
I'm a turbo guy, but with this set up you don't have to complain about any turbo lag.
I'd like to see what engine you'd call good sounding and efficient.

LiLJankie 1 year ago
@LiLJankie
I get that not all turbo set ups are going to have lag.. But we definitely run into lag with an itty bitty I-4 turning say, a gt-42. A huge turbo that will push 30lbs into a two litre engine past 10,000RPM.. But it won't make the boost til around 4k.. A big block however, will always be pushing enough air to have two of the moving by around 2k, virtually eliminating lag.. I'm in the new era, I don't use the term "no replacement for displacement."
Evancarrick12 1 year ago
@Evancarrick12 lol dude, the “new era” isn’t much different from the old. We’re still using the same basic engine they were using 100 year ago. And in all that time there never has been a replacement for displacement. Another way of putting it is anything you can do to a small engine, I can do to a bigger one and make more power. Simple physics.
Warblade118 1 year ago
@Warblade118
That;s nothing but obvious.. I'm not stupid.

@Evancarrick12 Um...that's a pretty patronizing remark to anyone who races a big block.

I think you'd be the first to say there's a little more to it than that.
Warblade118 1 year ago
@Warblade118
An engine makes power based on how much a/f it can burn. If I can make my dinky ass little 4g63 burn as much, and as reliably, as your big block, then yea, I'd say it's a bit more difficult.
More head pressure, more rod pressure, more crank pressure.Same amount of heat in much less volume.
It's not just about revving the piss out of something, it's about developing a working relationship between all the parts..

Warblade118 1 year ago
@Warblade118
Well you can just bolt up a new carb and replace an air filter for more power.. I don't see what the problem is.. That's simple.
But it's a bit more in depth build to get the same power out of 122ci as compared to 427ci.
I'm done with this conversation. My point is perfectly legitimate.

@Evancarrick12 oh and there still is no replacement for displacement when it comes to drag racing. you say add a turbo, i say put a turbo on the V8 and watch it kick the four bangers ass. the fastest drag cars in the world are big blocks not four bangers. and dont even say "well try to take a corner" cus hardly anyone races around corners on the street plus there are v8s and v10s that can take corners just fine
normanaw 1 year ago
@normanaw
I know, there really isn't a replacement for displacement.. Because all adding a blower does is gets more air.. the plus to a larger engine is that it flows more air, so a blower in a way adds displacement, much as EGR lowers displacement. There will never be any replacement for the big block, they're great. Just that if I see a DSM smoke an F-body, I'll respect the DSM'er a bit more.

Warblade118 1 year ago
@Warblade118
Well for a start more valves in head means greater surface area therefore better breathability. Less reciprocating mass means higher revrange. The ability to dail up seperate intake & exhaust timming (really handy with turbos) without having to change cams just use degree wheels. Smoother running (if you care about it) if on the street. I looked at your profile. You should already know these things, Or are you just testing me.
I know its prob a drag engine but drag aint everything.
blyndrotor 1 year ago
@blyndrotor It has nothing to do with "fear". It has to do with cost efficiency, mostly. Four times as many camshafts. Twice as many valve springs, valves, cam followers (aka "lifters" in pushrod engines), retainers, valve locks, valve seats, valve guides, valve seals, four times as many cam bearings, you get the picture. All of these components cost money. What are the measly benefits? 12.5% (at maximum) greater surface area of valve heads. Slightly reduced wear and stress on the valve train.
BugattiFan301 11 months ago
@blyndrotor What are the other minor benefits? Well, you can use a slightly higher compression ratio. But let's say you want to cnc port those heads. Well, that will cost you TWICE as much as it would with a 2-valve engine. And CNC porting is NOT cheap. Even though you may get ~20 psi greater Brake Mean Effective pressure with the same intake/exhaust design and profile, DOHC clearly costs WAY more than it is truly worth.

@TH3M0N3YM4K3R
The formula for the power of an engine: combustion pressure x displacement x revolutions per second x number of cylinders x factor for 2-stroke or 4-stroke
or: P = p x 1/4 x pie x d² x s x n x z x a
p = maximum pressure during combustion
d = piston diameter
s = piston stroke
n = number of rev / s
z = number of cylinders
a = 1 for a 2-stroke and 0.5 for 4-stroke. two stroke has a power stroke every revolution, four stroke has a power stroke every 2 revolutions.
TH3M0N3YM4K3R 2 years ago
So how do you get more power from an engine?
- Increases the capacity
- Increase the rev / s
- Increase the pressure by a turbo/supercharger for improved cylinder filling

Hahaha! You're using a 206D Supercharged 572 and only getting 1400 HP?! That's laughable, and you don't need DOHC to even get twice that power. Pro Mods Get 2500+ HP From 526 Cu in. with the same supercharger. Youo must either be getting very little (+- 20 lbs) boost, which is pitiful for this particular supercharger, or you are running a very shitty valvetrain with low lift and duration. You don't fuckin need a 206D to make 20 lbs boost!

Has it never occurred to you that dragsters don't use the bullshit gasoline that all of us get at the gas station on the corner? I guess not. A username like BugattiFan301 is evidence enough of that. Full on dragsters use high octane gas that contains triethyl lead, to give the fuel the resistance to detonation that is paramount in an engine that creates such extreme cylinder pressure. We all use UNLEADED fuel, that at best, is 94 octane. 87 is the norm 85 theshit Not 110, 112, or 118 race gas.
madtownmadman 1 year ago
Haha, pro mods don't use race gas, they use methanol. You don't know shit about drag racing. Admittedly, it is harder to get as much power without ruining your engine when you have low octane fuel. Also, admittedly, methanol does have an octane rating of 110+. But, still, this engine puts form WAY before function. Those cylinder heads have to cost an enormous amount of money, and you will have to pay for 4 camshafts instead of one and twice as many retainers, valve locks, and valve springs.
BugattiFan301 1 year ago
I never mentioned anything about Pro mod, and the type of fuel they use. My statement was general. To the point of 1400 hp being quite a stellar production for pump gas. I realize you said that Pro Mods use the same blower, and get 2500 hp with it. But then, they use methanol. Not pump gas. Just for the info, methanol carries an octane of about 119.
madtownmadman 1 year ago
On top of that, the supercharger costs ten thousand dollars when you could just buy a stage four 14-71 supercharger for four. I also noticed it has a dry sump oil system. This engine is simply impractically expensive and ridiculous. The only person who would even consider buying this is somebody who knows nothing about engines and has more money than sense.
BugattiFan301 1 year ago
Any engine that can make over 1400 hp on pump gas, is a stellar performer. With an even more stellar tuner. This engine makes more than 2.6 hp/ci
madtownmadman 1 year ago
ha, you guys tear me up, you can argue all the facts and figures you like but the proof is on the track. I suggest you both take your high power cars to the nearest drag strip and race! That is what these motors are built for, not powering forums!

Now, folks, true power, it is true, but this recipe is stolen from imports, who else has been using DOHC and fuel injection and computer ignition for decades? Euro/asian cars, not american.
2URBO2 2 years ago
Now, folks, listen to this moron. 2URBO2 thinks that there is an advantage that comes with OHC vs. OHV. Does your dumbass seriously not realize that OHC's and OHV's are just a way of controlling the camshaft, and have almost nothing to do with the engine it's self?
The only difference is, a chain and gear, instead of a pushrod, which OHV engines actually do incorporate, but only as a means of controlling the pushrods.
F.I.? Who cares, there are carbureted engines making 8,000+ HP.
kcole939 2 years ago
Now, you think OHV is cool because your cars are fitted with it, but it is not. OHV is cheap, and it is reliable because it is as old as it is uneffcient. 2 valves per cylinder is the maximum, while a dohc engine would have 3 times that. Now, in the last few decades the dohc engines have been developed more and more reliable, plus it is efficient. Just compare a 6 liter OHV V8 to a 6 liter DOHC V8. I have been on a engine repair shop, and worked for a month, so i know what im talking about.
2URBO2 2 years ago
OHV's are cool because they are simple, and they work. Why would you want to grind FOUR camshafts, when you could have far less of a parasitic loss by just spinning one camshaft, and using very light pushrods?
Why would you even want MORE valves? That is just simply more mass that has to be moved. The key to efficient power is simplicity. Why have more mass, when you can get the job done with 2 valves?
kcole939 2 years ago
since when has a timing chain, rocker arms, and 2x.5meter long pushrods been light and simple? i like pushrod engines but saying that an overhead cam engine isnt simpler is just dumb, theres a reason the world uses ohc's and 3,4 and 5 valve heads, its called improvment
racedemon89 2 years ago
Now, there are extremely high revving, high cubic inch engines. Top Fuel dragsters for example, they sometimes rev to 9,000 RPM, and create 8,000 Horsepower.
Do you know what they use? PUSHRODS.
Pushrods may be very light, if made in cast aluminum. OHC engines are typically NOT simple.
How would you figure that a Ferrari V12 with 5 valves per cylinder is SIMPLE? That is 60 very TINY valves.
As far as I'm concerned, the most powerful dragsters use simple old OHV tech. Enough said.
kcole939 2 years ago
ferraris and bugati 5 vaves are the minority most of europe and asia and the us may i add use 4 valve heads because it allows a central spark pug, a symetrical chamber and 4 slightly smaller valves will allow more flow than 2 bigger ones, and how long do top fuel dragsters last? you cant use something which relies on a $80,000 engine and the most volatile fuel in a car as proof. jst go ask on some forums im sure youll learn something
racedemon89 2 years ago
You're the one that needs to learn something. Any engine under 1,000 C.I.'s is going to tear it's self apart while producing 8,000 BHP.
There are daily driven 800 Horsepower 2 Valve Chevrolet Small Blocks. Just go to Nelson Racing Engine's site, or better yet, talk to someone that runs a twin turbo SBC in any GM car.
kcole939 2 years ago
Now, 2URBO2, or should I say, kiddo. Let's learn something. 'Advanced' engines that incorporate fuel injection, and OHC designs are more for ease of road use, despite the fact that many are used in racing of many kinds.
How the fuel gets into the engine is not of importance, the factor that counts is IF you're getting the right amount of fuel and air.
Beside the point, Chevrolet has been using various types of fuel injection since the 1950's, dipshit.
kcole939 2 years ago
Well, DOHC has been in use for a long time, and it is a reason "everyone" is using this technique, and not OHV, as americans do. But it's a reason for that, the OHV is cheap, and it is so simple that it will work dead on.... But there are disadvantages... They have easier valve floating, they cant rev as high as a OHC engine, there is more parts moving from cam to valve, so it can easily break.
2URBO2 2 years ago
Furthermore, to compare these 6.0 Liter OHC and OHV engines that you talk of, they would have to be equal to make it fair.
They would need heads with the same flow rate, the same compression, pistons, rods, and crankshafts of the same weight, they would need equally flowing intake manifolds, everything down to the intake filter would need to be equal.
THEN, maybe, just maybe, your dumbass would see that there is not THAT much of an advantage to OHC.
kcole939 2 years ago
As mentioned above, there is something called a MULTIVALVE engine. An OHV engine doesnt have that, a OHC engine have that. More valves = better flow = better torque and horsepower ratios.
Just look at Gumpert Apollo, it's direct fuel injected audi V8 engine of only 4.2 liter has up to 800 horses. Thats almost like a F1 engine.
2URBO2 2 years ago
As mentioned below, it does not matter how many valves a particular engine has. It matters if you're getting the job done, hence, flowing.
Yeah, look at the Gumpert Apollo, it's a direct injected Audi 4.2 V8 TWIN TURBO that makes up to 800 Horsepower. Is that all?
Listen, go to Nelson Racing Engines' website. They sell a Twin Turbo 5.8 Liter 355, which only uses 14 PSI of boost to create 800 HP, and 790 FT.-LBS.
Oh, you know what? It's a DAILY DRIVER SERIES engine, runs on pump gas.
kcole939 2 years ago
Idiot, Mercedes has indirect fuelinjection in the 50's too.
And the Daimler-Benz DB 601 had DIRECT fuel injection during WW2. Thats in the 1940s.....
2URBO2 2 years ago
Honestly, who even cares about fuel injection? Fuel injection helps with straightening out A/F ratios, which may yield a whole 5 Horsepower, and 2-3 MPG's depending on the car.
Also, with the OHC vs. OHV debate. OHC's advantage comes in the upper RPM's, which is excellent for small engines, but is not a concern with large engines (6.0+ Liters).
Engines that size have no need to rev high to make power, they have a thing called TORQUE. Which is why, OHV's have been a mainstay in the U.S.
kcole939 2 years ago
Well, there is something called multivalved engines, which OHV engines dont have. Better injection of air/fuel into the cylinder = better torque and horsepower ratios. Not only good for small engines.
2URBO2 2 years ago
That is a total assumption. So, you're saying that no 2V engine can flow as good as a 4V?
So you're saying that those Hemi engines in Top Fuel drag racing, aren't making the 8,000 BHP that they do, just because they mainly use 2V heads?
What you're not understand is, it's not the amount of valves that you have, it's what each valve flows. Intake/exhaust valves are not a one size fits all deal. You can go out and buy 2V heads that'll outflow any 4V head known to man.
kcole939 2 years ago
so you dont cae if your car only revs to 1000rpm
why have a 5000rpm redline and 1000hp when you can have a 7000rpm redline and 1200hp on the same motor?
and fuel injection helps with performance and economy (like it matters) and atmospheric onditions, ever had fuel vaporise in your pipes, or had to use a choke in the cold?
your logics so retarded.
racedemon89 2 years ago
Yeah, MY logic is retarded, yet you're a 21 year old kid who cannot even type up a correct sentence.
So you're saying, just raising the redline by 2,000 RPM, it will gain an engine 200 Horsepower? YOUR logic is fucking retarded.
Horsepower is calculated from revolutions, and Torque.
Horsepower = Torque X RPM / 5,252.
What you said is possible, but with most E.F.I. and Carb setups used on dragsters these days, they peak around 6,500, in the case of most BB's.
kcole939 2 years ago
what makes more power.... 400ft lb's at a 5k redline, or 400ft lb's at a 7k redline, the cat 797 makes 2300hp but only revs to maybe 2000rpm, if it could rev to 3000 it would be more powerful, (well ok if the torque was moved further up the rev range which in that scenario isnt useful but still the idea is correct)
racedemon89 2 years ago
400 FT.-LBS. at 7,000 RPM, of course. You're missing the main point though. The powerband characteristics. You cannot just instantly go from producing that amount of Torque at 5,000 RPM, to 7,000 RPM.
It would require massive amounts of boost, a far more radical camshaft, far stronger pistons. Most likely a different manifold, and a different E.F.I. or Carb setup. Just to get the correct flow characteristics.
The idea is correct, but not realistic at all without major improvements.
kcole939 2 years ago
well noone said powers easy to make, the arguement is wether ohv (with valves) is better than dohc with 4, my view is dohc opens more possibilitys but you should base your engine around its intended use.
when just trying to move a car, not racing, not just barely moving but a purely usable engine a 2.0-2.4 liter 4 with dohc and a turbo making 240 hp is more than adaquate. so why would you ever need a 5.7l ohv gas guzler for the same purpose (other than refinement which is fair enough)
racedemon89 2 years ago
Now don't get me wrong. I love forced induction, turbochargers are about the neatest thing around. But, why opt for smaller displacement?
With a 350 Chevrolet Small Block, you can make nearly roughly 800 Horsepower with a mild tune, less than 15 PSI, and pump gas. Perfectly streetable.
How many 800 Horsepower, low boost, pump gas Evo's have you seen? Have you seen any that are even mildly streetable?
I rest my case. More displacement wins, always.
kcole939 2 years ago
"OHC's advantage comes in the upper RPM's, which is excellent for small engines, but is not a concern with large engines (6.0+ Liters).
Engines that size have no need to rev high to make power"
another way to look at it is a dohc high revving engine doesnt need to be that big to make power (great now i sound like a ricer lol)
evo fq 400;DOHC 2l turbo 400+hp
jaguar xk;DOHC4.2l 400+hp v8
lightly tuned chevvy;OHV 5.7l 400+hp
so why would you have an extra 1.7l
racedemon89 2 years ago
Why would you want only 2 Litres of displacement, or 4.2 Litres of displacement, when you can make more power with a bigger engine, naturally aspirated in most cases?
Do you know what supercharging, or turbocharging an engine does? It essentially increases it's DISPLACEMENT. More air is being displace. That's all it is, more air forced in, to increase displacement.
Now in literal terms, it is not making the engine any bigger, yet, it is actually increasing displacement.
