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
