Hey guys help me answer a question I have.........is a Pontiac 400 block any wider than a Chevy 350?? I'm thinking no but my buddy swears up and down that it is. And also, would a 400 out of a 70' GTO bolt up to say a Chevy TH400?

Thanks guys :thumbup:

Question #1: Definitely wider.

Question #2: The lower 4 bellhousing bolts will line up but not the top 2 but there are adapters available.
