Happy Ford/Mercury day! 4/29 ( for Snake)


Recommended Posts

Back when nascar rules about engines /production cars. Auto companies had to produce enough of both to be able to be used in racing. Ford/ Mercury come up with the 429 Which even found there way under the hood of Colony Park wagons!

Well, sort of. The 429 used by NASCAR was the Boss 429 which used the archeology of the 385 series of 429/460 blocks, but used Blue Crescent aluminum heads -a hemi-head version with a giant Holley Dominator on the intake manifold. As far as I know, no competitive teams used the standard, Cobra Jet or Super Cobra Jet 429 engines in competition. The 427 FE and the then the 351 Cleveland was the choice of Ford drivers. Eventually that engine became the Clevor (Windsor block/Cleveland heads) and finally FR series of racing engines.

Yes, and to qualify the Boss 429 engine for racing use Ford put them in the Mustang despite having the 428 engines that made better for everyday use.  If a customer wanted a/c or an automatic the Boss 429 was not going home with them.

Yes it's a bit strange NASCAR allowed the Boss 429 in the Ford Torino and Mercury Cyclone when these cars weren't available with this particular engine.
I mean, Mopar did it fairly right because except for 1964-65 Race Hemi the 426 Hemi was indeed available to get for a customer in the car models used on track in NASCAR racing.
Today it's different because the Ford FR9 they use now developed and built by Roush-Yates is not available in any car, it's not related to any other engine as they started with a clean sheet and designed it from scratch especially for NASCAR use
