Hey everyone I'm new here and could use some some help. I have a 82 cutlass supreme with the buick v6 231 in it. I would like to swap that out and either put in a buick 350 or 455. I know the 350 should swap right in, but I was wondering what has to be done to swap a buick 455 so it will fit correctly. I hope this is the right section to post this in, Thanks in advance.
