Ive been trying to find a answer to this question for the last month but I cant find a decent forum. I have a 55 Buick Special with the 264 and a Dynaflow, as most of you guys know performance parts for a 264 and even a 322 are like non-existent. I want to swap a 364,401, or 425 in there. A friend of mine has a good running 401 I can have for free, is there a way to put this motor in with out monster fabrication? I found out the bell housing from a 57 Buick will bolt to my Dynaflow and give me the later bell style, what I'm wondering is can I use the motor mounts out of a 57 which came with a 364 in my 55 and then bolt them to the 401? I can do motor swaps I'm just not much of a fabricator so that would be the only thing worrying me.
