I don't know if this is the appropriate place to ask this, what with it being a Turbo V6 site mostly, but I was wondering if anyone knew.

I know that with the Oldsmobile V8s, the difference between small block and big block is only in the deck height, everything else is identical.

But what about the Buick 350 versus the Buick 430 and 455. I understand that the 430 and 455 have the same outer dimensions, but how is the 350 related to them?
