The Boss 429 engine was a NASCAR engine detuned in an attempt to work in a street car. With the proper camshaft and carburetor, the were designed to run at 7500+ rpm for hours on end. Most mass produced big block V8s at the time were lucky if their power curve lasted up until 5000 rpm. The Boss 429 was a superspeedway engine, not a drag racing engine.
Boss 302 was not its predecessor. It ran alongside for a different purpose. From the factory the Boss 351 was faster. Most drag racers of the time preferred the FE 427s over this 429 hemi, until they figured out how to tune them to run.
@smirkinatu5512. Its a bait title, lol. Chevy guy reads that and it's 🤨 WTF you say ? So we click on it and he gets views. But ya the smaller engined '67 396 Camaro ate the Boss '9's lunch daily and if we called in the dealer 427 swapped camaros they'd be staying for supper too. Not gonna lie though those '69 and 70 429 mustangs are gorgeous cars.
I have some of the original road tests of the Boss 429 and, without digging them all out of the collection, I recall one test (High Performance Cars), expressed some reservation about the car's performance. Another test I have in front of me, from July 69 Car Life, recorded 14.09 at 103 mph. Top speed was 118 mph with a 3.91 gear. Also, there was a batch of the 69s produced with the wrong valve springs. I was a Ford nut back then and big into the street racing scene in 69-70. I lived in a relatively muscle car intense area (far west suburban Chicago). I saw a grand total of two Boss nines on the street in those days.
I was born in 1962 by the early seventies this particular Mustang was my favorite. Long before it was ever an icon. I want you people to know this I hate your guts for your appreciation of this car because it has forever taking me out of the price range of ever being able to own one of these. You copied me I didn't copy you😂😂😂
Actual HP was significantly higher than 375. Remember, this was the time of Detroit posting lower HP ratings to satisfy insurance companies, and an ever increasing involvement of the government. It might have put out 375 at say 5,000 rpm. But at 6,200, it was more like 475. The real drawback for this monster power house was that Ford designed it for NASCAR, and used porting, camshaft, carburetion, etc. to achieve best results at steady, high speed track conditions. That did not translate to ideal dead start acceleration figures. With some relatively minor work, this engine would destroy most anything else on the street!
The horsepower and torque produced for the same volume of hydrogen fuel would be significantly higher than gasoline in the same internal combustion engine. This is because hydrogen has a much higher energy density than gasoline, so it will produce more power per unit of volume. Overall, hydrogen-powered engines have the potential to produce significantly more power than gasoline engines. For example: If the Boss 429 was powered by hydrogen, it would likely produce around 1500 horsepower and 1200 lb-ft of torque. This would make it one of the most powerful engines ever produced.
No rivals? 1969 Camaro SS/396 could beat these all day long and the GM 396 L78 engine had better low to midrange power than the Boss 429. You could even step it up from there and spend a little bit more money for the COPO or Yenko with a 427 and they will lay out Mustangs all day long.
I got to drive a convertible GT. It was one of the first years of production I wish I could remember which year. That thing was a death trap. Sure it was fun at first but the tires and brakes were awful. Full resto.

All you bow tie bozos and mo po fans, fact# Boss 429 is one of the most powerful capable engines ever designed along with surprise the 427 soch which put out over 600hp back in 1964. Currently an engine builder, Jon Kassie builds an 800+ cu in Boss motor that puts out 2000hp naturaly asperated. Put that in your tailpipes 😂
The exhaust choked the engine, the cam was way too small, the intake and carb was incorrect and too small. On the dyno it was lucky to make 350hp. A good sbc could out run a boss 429 from the factory. But the potential was there to make good power.@@sergeantmasson3669
Ford won more races with the BOSS 429 and the Torino Talladega in 69 and 70 than anyone else in NASCAR. Ford purposely rated the Boss 429 at 375 HP but many independent dyno testing had it at 550. Ford lied about the hp to decrease insurance costs, from factory they made nearly 500hp.

A BOSS 429 with dual quads and slicks did a quarter in 10 seconds.
My dream car.
Its just a shame it came with a wimpy 735 cfm carb and a grocery.cart cam shaft. It was capable of so much more performance.

Wasn't the Mach 1 with 428 SCJ with super drag pack faster?
@@garysarnowski3113 Much depends on rear gear ratios and tuning.
BOSS 429 baby !!!.....oh my lord i drool
My dad had one. It was yellow and black.
Lmao
There’s a list of cars that would rock this boat anchor.
Give me the list with facts. Not your B.S
Actually, the Hemi beat it in a straight line.
Boss 351 kicked all their
uhh no..
It was actually quicker thru the 1/4 mile but definitely not as desired as the 69/70 Boss 429
Feels like AI generated content
hillarious..the 67-corvette -327..had 375 h.powers!!!...week...
I never like the wire hood hold downs but everything else about that car was the best car from Ford 69 was the year
Evidently no one here has ever heard of the 70 Hemicuda
Please dude. This isn’t the fiat channel

Only 375hp but still my fave Mustang.
Yes because it was vastly restricted from the factory. The 429 scj had the same rating stock

@@Loulovesspeed the crank hp rating was correct but the engines where basically restricted from the factory ( intake, exhaust, carb, cam and timing)
