The Shocking Truth behind Ford’s Banned BOSS 429 Engine!

[@turbo32coupe]

The problem with all the hemi engines is that the camber volume is too high. To get high compression, it requires a domed piston. This impedes flame front travel and reduces power. Don Garlits used to run 50 degrees advance on the 426 to compensate for this. All the hemis came into there own when boosted as this allowed a flat top piston. With the spark plug in the middle of the chamber, this was a great improvement over wedge heads.

[@rarecarstorys]

@turbo32coupe Ah, the hemi engines-where the camber volume is like that one friend who always shows up uninvited to the party! But hey, at least we can count on Don Garlits to bring the spark with 50 degrees of advance!

[@donbrutcher4501]

The street 429 also had smaller and heavier intake valves.

[@BubbaSmurft]

@rarecarstorys Camber is the tilt of the wheels and is a suspension setting, CHAMBER is a place where combustion takes place. Y'all'd think that someone that called the sock a camera 4 times would take a sec' to assure they spelled something correctly and didn't repeat a mistake... again!

But the Forfd Boss 429 is a crescent Hemi, which is a better street design. Ford choked the engine down as it was only concerned about NASCAR performance. Had emmisions regs had not hit, the Boss 429 would have conquered the street as well

[@jamesmcknight6440]

When engine masters ran a contest, anyone who could make an engine with the highest torque with the lowest hp would win the contest, the 429 engine took the prize everytime

[@rarecarstorys]

[@TheReal1953]

In HS, the 428s beat the 429....we didn't see the point of the 429. Nice to understand now why Ford let that happen.

[@robertkerr4199]

Cammer.. not camera

[@bigb4894]

With huge intake ports, the speed of the air/fuel going through is too slow at street speeds and the fuel falls out of suspension and also the air doesn't really have a "running" start to fill the chamber as soon as the intake valve opens. A good street engine doesn't work well on the track and a good track engine doesn't work well on the street.

[@JesusServant-Z]

351 Clevelands also have issues on the street. the 4v or "4 barrell" heads have BIG ports and don't work well on the street, the 2V or "2 barrell" heads are better for a street car.

Same old story, FORD brings the Heat and Sanctioning Bodies take $$$ from the competition who can’t compete then the BANS ensue. AI Narrations Suck dirty ass.

[@2011metalmaniac]

I only learned yesterday that Ford in 1964 launched a 4.2 quad cam 32V motor with fuel injection. I believe that if they had been aloud to run the cammers. We would have had a coyote type engine in the early seventies.

[@chrisredfern1882]

Every manufacturer had a product to compete, NASCAR as usual slowed engineering.

[@buildingracingvideos4714]

This is why the hemi is the benchmark. It won in nascar and drag racing. At 426 cubes and 500 cubes. On the street, traction was the issue not being sluggish. The only winning engine with no excuses.

[@frankjohnson6342]

@@mikeabney1214 You get the same 1000 hp (but not the torque) from a 358” R5 P7 Dodge NASCAR engine but with a cam with specs for drag racing to give it a peak higher hp over the circle track wide flat hp plane from 7000 rpm to 9500 rpm. Amazing what time and technology has changed how much more power can be pulled out of a much smaller naturally aspirated engine than was possible in 1970.

@donbrutcher4501 From the factory they were so badly detuned and fact is Ford produced only about 500 of these cars . It wasn't until John Kaase got busy improving these engines that they took off.

This was the engine that forced the '69 Hemi Daytona Dodge Charger and the '70 Plymouth Hemi Superbird into existence. The street version was kinda mediocre (mismatched combo: huge port cylinder heads, tiny cam, waaaaay too small intake manifold and carburetor), but it didn't take a lot to wake it up.

[@rarecarstorys]

@wesleyperson3402 You're absolutely right! The BOSS 429 certainly had a significant impact on the muscle car wars, and it’s fascinating how it pushed competitors to innovate.

[@anthonytumbarello9940]

@wesleyperson3402 that is an incorrect statement. The wing cars were dominant on the super Speedways and NASCAR again did not want specialized vehicles with big blocks. The wing cars did race in 1971 but could not have an engine bigger than 305 then in 1972 NASCAR ruled out all areo cars.

[@wesleyperson3402]

@anthonytumbarello9940 Actually it's not, because the Talladega Torino came before the Daytona Charger and the Plymouth Superbird. The '68 HEMI Charger 500 kinda sorta solved the front end aerodynamics challenge, but the flush grill and headlight design created so much down force out front that the rear end would actually start to lift at high speeds. Enter the '69 Torino Talladega, which solved the rear down force problem, plus the track version of the Boss 429 had a slight horsepower advantage due to the Boss's slightly larger ports and valves than the Race Hemi, ok plus the Holley Dominator that was designed especially for the Boss didn't hurt either. That sent Chrysler back to the drawing board in the aerodynamics department, thus the '69 Daytona Charger and '70 Plymouth Superbird were born.

@rarecarstorys Ask around; there are plenty of unemployed actors who will likely do your narration for free, just for the exposure, just be sure to give them credit at the end of your video, or even at the beginning as used to be done many years ago. Using AI narration which stinks only makes your product, and you, seem unprofessional and unworthy of ever becoming a producer of decent video production or editing. Far too many 'influencers' are shooting themselves in the foot, by uploading poorly edited videos, because no one who sees stuff of this quality, will never hire you to do any work for them.
