  • Beautiful car!

  • Ok, so within 5 mins, not 6 but 5 mins, I have got a dozen folks telling me i"m full of shit....next weekend I will take a video of the same license plate and the car in the garage. Will post. 6 days and counting. STFU. It's my pop's car. And has more NOS than in this vid. Fuck the haters.

  • That's my Dad's car ! He's got that same TX plate hangin in the garage.

    And, for all the shit talkers and naysayers, the original poster of this video knows whom he sold it to.

    I love riding in it.

  • Dahmn NICE.

  • The '71 Skyline had 160 hp from the S20 2L twincam six, and 250hp in race form - it would've made a good race back in the day, very nice Stang by the way! The '71-'73 were my favourites since the original Gone in 60 seconds movie

  • With alittle more compression(12-1 or better),alittle more camshaft then stock and headers this car was deadly on the steet in its day. I won alot of $ in the day street racing against big block chevys. stock heads with alittle port clean up would pull right to 7000 rpm with those big valves and ports.. Nice car...

  • @BOSSMACH351 Lmao, lol when I get a 71 mach1 for my 17th bday, you gotta tell me all this shit involving the tweaking

  • No the BOSS 351 was not a Hemi , but it did have canted valves , it was rated at 33o brake HP@ 5400 RPM , 370 lbs-ft torque @ 4000 RPM. The BOSS 351 had forged Aluminum alloy pistons, balanced crankshaft , 4 bolt main bearings caps,HD magnafluxed & shot peened connecting rods , high lift cam, & solid machanical lifters .

  • did the boss 351 have a hemi engine?

  • REV IT FOR FUCK SAKE

  • I just bought the same car. hopefully it turns out as nice as yours! by the way it is from texas

  • texas god damnit

  • 12:1 ???????

    Get out!!

  • cleveland block = big heads made in cleveland,ohio.....windsor block small heads,made in windsor ,canada.....

  • Hey Spywell, why are you so FOS? A 133mph at only 11.3? You got a stock turbo or supercharger? Take an EXLAX and get some relief.

  • One comment I need to make since someone mentioned abiut the carburetor. The original carburetor is an Autolite 4300D which was only used on the 1806 Boss 351s. I have one of these carbs in mint condition, however I run a 780 cfm vacuum secondary Holley with Proform main body for better performance. I previously used a 750 cfm double pumper, but the car likes the 780 cfm vacuum secondary better.

  • LOL, listen to that door close!!!! SOLID!

  • they dont make em like they used to : /

  • AH! finally someone stands some ground. 1 discrepancy I'm aware of is production #'s 1805-1806. At least that was an issue when I worked at Mstngs Unl. Some auto's were installed "at the dealership" only, Never the factory. Also the rear spoilers were faced opposite of Mach's. Rear valance no cut-out's. solid lifter, etc, etc., only thing close to the boss was the even rarer, under 400 produced, '72 351 R-code H.O. I bet everyone had one of them too. I suppose everyone means well though.

  • If some Boss cars got Automatics at the dealership, what did Ford use for a torque converter to work with the solid lifter longer duration cam and be streetable? How about a trans cooler for the higher converter temp? I have owned my B351 for 30 years now and am the 2nd owner. My car never had the exhaust tip cutout vallance either. later outersun

  • Not sure what torque conv. were installed, I'm sure some stall, which wouldn't be that difficult since other manufacturers were capable of doing so. The (2) I've seen did have trans coolers however. Both were certifiably dealer installed auto's with one having the clutch pedal still hanging. Back in '83 I met a guy in Maryland who "claims" his was "factory" installed with 4.30 detroit locker and he had documents to prove. I too have owned a 351 boss but sold out and went mopar. Cheer's to you.

  • you seem like you know allot about these old 351s. What is the difference between cleveland and windsor? How many variants of these are around?  How does this compare to 302 is it the same block? What is needed to get this kinda rpms and power out of a 70's windsor engine out of a bronco?

  • I have a '72 Special Edition Mustang Fastback Sportsroof 351 Cleveland R-code H.O. 4v V8

    It has 2 First place trophies and a second place trophy for doing 11.3 # 133MPH Stock.

    (It is not a BOSS, it is much Lighter and much Faster)

    Among the Rarest and Fastest Mustangs ever produced.

  • It didn't come from the factory lighter or much faster.

  • Is there no one out there that knows what a Boss 351 is? ONLY the BOSS 351 received the BOSS 351 engine! NO Mach 1 or other Mustang, understand? There were only 1806 cars made but the way people talk like everyone had one. They did NOT come from the factory with a Holley carb, but a 750cfm Autolite. All were 4 speeds. I can't believe after all these years, people are still clueless.

  • Comment removed

  • Had a 71 Mach1 myself. I love how nice this one looks and sounds.

    somebody yanked the 351 Boss before I got it for a stock car. They left the C6 tranny and I dropped a 69 351 Windsor that had factory 10 1/2 to 1 pistons. Not as bad as a Boss but it ran great and still burned the tires anytime and anywhere.

  • This horsepower is made naturally aspirated with no power adders and through a restrictive 2.25 inch diameter exhaust and factory mufflers. This setup seriously hampers power with this cam. Headers into a 2.5 inch exhaust with Flowmasters or similar is worth another 50 horsepower for sure. Add a some tuning and 500 horsepower is within reach. I ran this car against a Kawasaki Ninja and gave him the run of his life. 3.91 gear, factory Hurst shifter, wide ratio toploader transmission & 750 Holley.

  • I have owned my Boss for 30 years now and am the second owner, Mine was originally light pewter metallic like yours. I bet you get all sorts of flakes calling it a Mach i. The 351 was the king of the Bosses for sure. I have put over 100k miles on it since i bought it and still plan on driving and enjoying it like you are, Bravo! Make sure you keep all Boss specific parts cuz they are rare.

  • Thanks, boss351dude ! Glad that there are others out there that appreciate these cars. This car is basically a nuts-and-bolts restoration, with some internal engine mods. Externally, I only changed the carb from the Autolite 4300D (safely stored away) to the 750 Holley Double Pumper using a factory Ford over the counter Holley flange intake manifold. This manifold looks identical to the stock Boss manifold but in the part number suffix. The Holley carb really woke up this engine combination.

  • I'm the owner of this car and it now makes 425 horsepower at 6800 rpm. Revs easily to 7500 rpm and I've shifted frequently at 7200 rpm. I run CAM2 110 ocatane leaded racing fuel. As for a boat anchor engine, the 351 Cleaveland in Boss form was one of the most powerful small block made before 1990 or so. It have HUGE ports and the 1971 Boss 351 was the fastetst Boss out od the factory, even faster than the Boss 429. How about 351 cubes revving to 7500 rpm you Honda guys !

  • I had a 1970 Mach 1 with a 351 Cleveland 4 Barrel back in the 1970's. Only mod was full length Crager Hot Pipe headers. I always wanted to drop a Boss 351 engine into my 70. How much lighter was the 1970 Mach1 Cleveland then your 1971 Boss 351?

  • @Longlakedreaming It's my dream to do the same thing to my 70 302. Great minds think alike!

  • obviously georgenfla has no idea what hes talking about but beautiful car none the less

  • Kartfag, Im smoking Signature Lights. I am very not stupid. If you can't deal with honesty, integrity, and near genius, then you should not sign on the internet. You are in denial.

  • Tabulus, I guess since you are just a little girlie-fag living in New Jersey, thats the best way you can justify liking your sugar daddy's broken down old mustang.

  • stfu asshole, im guessin ure some cali-fag or something???

  • Jersey? No way man! Dude i'm beginning think you're putting us all on.

  • Very nice, very rare! Also quite unknown...

  • Insane amounts of ignorance in these comments places. It's crazy!

    That's an awesome car though. I used to like the 302's as my favorite Boss, but things have changed the more and more I learn about the '71 351.

  • dude youre fuckin stupid... "cant develop any horesepower" wtf??? man what are you smokin???

  • So what kind of gas do you put in this?

  • 12 to 1 compression. if u dont want misfiring or detonation/ pre ignition you gotta run it on premium. i mean you can have fun in other cars but nothing compares to a big throbbin rediculously loud torquey badass v8

  • I think he meant pump gas or race gas. If this is an all aluminum engine, pump gas is a possibility, though I've heard people say they've run 12:1 on an all iron engine (block and heads), they just used a big cam. I'd be interested to know which one he runs myself....

  • @crezzyman my bro's hi-po 351c has super high compression, solid roller cam, etc., etc... it will run on 93, but detonates and generally runs like poo. It really loves 114 octane.. runs like a dream on that stuff.

  • Such big mouths for such little sissy-boys. You girls wouldn't know horsepower if it hit you in your ovaries!!!

  • Nothing moves like a Mustang!

  • 427 Roush is the only good one today besides Saleen Extreme!

  • I owned a 71 , red on black, but not as viscous as yours.....NICE

  • Hey GeorgenFag

    When you give up on your 4-cylinders, because you keep getting beat by our "boat anchors", and get a real car, THEN post a legitimate comment.

  • And...guys that drive Honda Civis are the "Gangsta's" of the Universe? 1 question...How does a fart can + Wing (For a FWD car none the less) make your car go faster?

  • My question is how high does your civic and your S2000 rev? I think the S2000 revs to over 8,000 RPM. So how does that work on the street? You have no low power, so you can't smoke the tires from a stop, and you can't get into the fun without winding that little engine up sky high. So, it's more prone to breakage too. So why is this better than an American V8?

  • better mileage. fun to dog the living fuck out of it till it blows. and they need the extra 3000rpm just to keep up with american cars. if they raced and shifted at 62 or 65 like some muscle does theyd be fucked. america. FUCK YEA

  • What the fuck is a mary like you commenting on this video. This car was made in 1971. I laugh at what passed for performance in Japan in 1971, when Skylines had a bone-chilling 89 horsepower. Sad that this 37 year old, SUV-sized car with a "boat anchor" engine can still crush a 2007 Civic Si in the quarter mile. In 37 years, no one is even going to remember what a Civic was because they'll all have been sent to the scrapheap and melted into sets of plastic spoons.

  • right on man!!

    "plastic spoons" lmao!

  • @tubulus3 Those ricers just can't last man, I'd much rather have quailty over cheap price.

  • JAJAJAJA what an idiot... its not only bout the horses, its more about the torque, this boat anchor as you call it can beat the hell out of those japanese cars that sound like my girlfriends hair dryer

  • spoken like a true fan boy. I dont think you even understand what horsepower is. You prbably drive a fiesta.

  • u need to fuckin grow a set a balls and learn not to say to us " commy' americans. will kick jap shit off the road. and hp per litre is fuckin stupid. especially when u have only 1.6 or 1.8 litres u new age pos car driven nigger

  • Its something called efficiency. I doubt you've heard of the word. I LOVE my muscle, but you cant down on good engineering. To say you cant have good fun on a track in something like a 2L s2000 is just ignorant. When i see a V8 put less than 200 horses down, thats just sorry.

  • wow. no comment.

  • The ONLY decent foreign engie I have seen, was in a Toyota Supra..oh but that was a German Made Engine at the time..

  • the biggest mustang ever made ( size )

  • I dunno, the new Shelby 500's are porkers too.

  • The only Jap cars that put out 100 hp per "liter" are Turbo/or/supercharged. The Ford GT is supercharged. Now read a list of Jap cars that can stay with that? Short list, huh. John Force's "mustang" has 500 cubic inches (I'm not French) and 8500 hp. With pushrods and 2 valves per cyl. What Jap car competes with that? Sounds like you've been pulling someone's "lil pecker".

  • Uhh, Georgenfla, there is a bid difference between a 4 cylinder putting out 90 horsepower and ANY engine putting out 500... Lets try to be a little more realistic.

  • What's the difference between BOSS and MACH?

  • There are only 3 different 351s, and they are all considered boat anchors.

  • i have a 351 what u called boat anchor.way stronger than any thing ull ever have.but your comparing them to japanese motors,ur sad enjoy ur rice

  • BAMF

  • awesome... the dude that said that it should have been replace with a honda civic is sick!! this is the second best ford.. nr 1 is ealenor:)

  • VERY nice, i have a 351bigblock and would love to convert it to a boss... whats the difference besides obvious horsepower?

  • Dude, there's no such thing as a "351 big block." All 351's are considered small blocks. There are 3 types, the 351-Cleveland, 351-Windsor, and 351-M (which most people call the 351-Modified). All 3 have different blocks and heads. The Boss 351 is a 351-Cleveland with 4-barrel heads, forged pistons, aluminum intake, mechanical cam, and a Holley carb, all factory.

    Get some engine books and car magazines and read. That's the best way to learn this shit.

  • That car is huge, it looks like an SUV. Whats up with the washing machine drum where the fuel injection runners should be? What a hunk of crap! Trade that thing in on something new and fast like a Honda Civic Si or a used Supra turbo.

  • yea im not one to start stuff on the internet usually but im a huge ford fan and i love classic mustangs and unless your kidding i dont know why your even commenting this vid...sorry we all dont drive Rice Burner piles of garbage

  • o yea and i forgot to say the car looks awesome and the engine sounds mean

  • Georgenfla, if you were 18 I would believe that you're serious, but since you're 49, I know that you're just pulling our dicks to get a rise out of us. Get a hobby.

  • lol, you cant smoke a joint and listen to classic rock in a japanese machine.

  • Sounds very healthy. It would be nice to hear the engine reved up and maybe see it run on the street.

  • So what quarter mile times does it run?

  • it would be about 14-15 seconds per quarter

  • Bit faster than that....

  • Hello from Australia Monster of a Boss fantastic resto did you end up selling it I was watching it on E-bay let me Know ??

    Cheers

  • What brand are those Magnum 500 wheels?

  • What a beautiful car. My friend's dad has a Boss 351, but it has the metallic green paint. Hopefully I'll be able to buy it someday if I get some money!

  • ya man im always lookn up pick of the 71,72,73 im teying to find a sweet paint job for mine im 18 i got it when i was 15 for $400 no motor iv been workn on it sins , iv got better i got a sweet job at a body shop with some sweet guys im tryin to put a vid to getter ill tell you when its ready to see what you think of my car

  • Hey guys, many thanks for the kind words! I love '72s and '73s, too. Love the big mustangs (drove a '71 coupe in HS 20 years ago). since then, the B1 was/is at the top of my want list.

  • Super nice car, factory tach, four speed, clock, tape deck, etc... I have a 73, but not as nice as yours. Beautiful Mustang man!

  • hey thats a nice car i have one like it but a 72
