If not a 455 - maybe a 427 or 454?
#1
I have a post asking what I need to do to drop a 455 into a 73 cutlass supreme. If the guy building the motor can't find a 455 core can I bolt in a 427 or 454? same questions as the other. I know I need to change the trans but do I need to weld different motor mounts or will this motor just drop in?
thanks

Yes you can just drop in a 454. The only thing that I had to change so far was the motor brakets on the frame. they are from year one for a 1970 chevelle. I was lucky my transmission was a unibell turbo 350. so far every thing is working out great.
