My dad has a 54 buick with a 322 nailhead in it and i guess this has the closed driveline set up...he wants to put a open drive line in it but keep his 322...has alot of goodies on this motor...if i understood him right he wants to know if the bell housing from his dynaflow will fit on a later model dynaflow...he said that the 322 has a different size bolt pattern than a later 401 or 425...he has found a guy that has a 64 wildcat..the guy took the motor but my dad was thinking of trying to get the ****** and rear end to work in his 54
Not sure if an early Dynaflow bell will fit a later transmission, but a '64 Wildcat most likely had the first TH400 in it anyway.
The '64 trans will not fit your '54 nailhead. There are options available, though. I can't tell you all the details, but go to the Buick nailhead groop on Yahoo and you will get all the info there. If you are in SoCal, PM me, I may be able to help with a few parts. Happy wrenching, Doug Cook
