[@MrHP463]

Im the driver of this car, the owner is standing beside the car in the burnout box. We bring the car out once a year to Tulsa and make 1 or 2 passes. This engine configuration we tried to simulate the Can-Am Boss 494 all aluminum engine. The heads are Factory Ford Experimental Holman/Moody nascar D port. The 2x4 manifold is a very rare Factory Ford and I made spacer plates to turn the big carbs sideways. I shift at about 8000rpm. Thanks for all the great comments!

Has the car ever been dynoed?

[@MrHP463]

Erik Hansen Yes we tried but at 6100rpm the engine nearly destroyed the dyno breaking the pump and blowing the hydraulic lines off. It was making 1060hp when the dyno broke. So we figure it makes around 1100-1200hp. Engine is built by the owner. I help tune the clutch.

When he lost to a 70 440 6pk 4 spd challenger he brought out his 70 boss 429 and beat the dodge by 5 car lengths .Super fast and the idle from a boss 429 would shrivel the nuts of anyone stupid enough to line up alongside THE BEAST .

Impressive time. The Boss 429 was designed for NASCAR to compete with the 426 Hemi, and it did a good job of it; however, the Mustangs and Cyclones and Torinos that got the engine for the street were rather disappointing in stock form. I think because on the street the engine just wasn't up at high rpms enough to take advantage of the big valves. But it was at high rpm about all the time on the NASCAR tracks, so it would really breathe there.

[@GeorgeMcKinley.]

@@gordonipock9385 the heads on the street version are highly restricted , they simply need a good porting job ( or better yet match ported with the intake manifold ) and they really come to life, very easy to get 600+ hp out of these.

There is one thing some people do who really don't know engines, is when you come off high rpms if you suddenly release the throttle and let the engine brake the car you can really damage the internals of the engine, such as bent pushrods, etc. The professional way is to immediately knock the engine into neutral so the the rpms can drop without pressure and stress on the parts, ask any pro, plus by doing it this way you can get a better reading of what's going on inside of the engine when checking the plugs.

Double clutch like Steve McQueen in the movie Bullitt, witch laid the blueprintfor all car chase scenes. The driver was super quick or he had a kill switch on the tranny to engage between shifts. Racing motorcycles use this trick setup.Richard S.

[@Lightning546]

Nascar drivers take it out of gear and then shut the motor off immediately after crossing the start/finish line after their qualifying run, (that was when they were still running qualifying sessions pre-pandemic). Most of them take it out of gear and then let it coast around the track and after entering pit road and they'll usually shut it off once parked and then let their pit crew push it back into their hauler for the ride home. Those engines (if they don't have a dedicated engine shop) cost $100,000 to lease for one race.

There was nobody in NASCAR or NHRA doing anything with Ford that they H/M didn't sell parts to. If you ran a Ford, you BEGGED H/M for parts just to run midpack against their picked driver.... There are alot of people that really boost Mopar's ego about the 60's. But I went back and added it up, and Mopar only got 15 or so more wins than Ford, 200 less top 5's and 500 less top 10's than Ford all said and done, between 1960-1971... Chrysler had their engine tech scientists in a lab. Holman Moody was Holman Moody. Stood all by themselves... People talk shit about the 70-71 season for Mopar beating the hell out of Ford. But in the same breath they want to talk about the 64 season that Petty and the big names had to sit out... Well same can be said for Ford in the 70-71 season. Likely H/M had very little dealings with the 351W or the 351C to really do anything for advancing the performance of those engines... So for Ford it was run the 351 of the 2 configurations and stay home, much like for the Mopars in 64, it was run the older 413's or stay home...

I had a 1968 428 Mustang CJ, and it ran in the 10's With substantially less horsepower than a boss. Hope you aren't taking the stock "horsepower rating" to heart. Of course, the real Boss had 1 carb...and this one has 2...uh.....those aren't Holley carbs, and they look like come faux-carb fuel injection units.
