One's small, one's big. Small blocks went to about 400ci stock, and big blocks started at 393 (I think) and went to 496 stock. Through GMPP you can get a 632 BBC, or perhaps larger now. There's also aftermarket SBCs that go up to a hair over 454ci.

 

 

 

Very few things that fit a SBC fit a BBC. They're really totally different motors.

 

 

But I'm not as brushed up on my GM stuff as I used to be.
