This is just a FYI and forgive me if I'm just repeating something you already know, but the vaunted "small-block Chevy" underwent a total redesign a few years back and what emerged was still a a small-block in size (it had the same bore-center spacing, 4 4",) but NO interchangeable parts with the original small-block motor. NONE. It was a BIG improvement is a lot of ways and has amassed a cult-following in just a few short years, to the extent that the hot rod-based magazines have fallen all over themselves featuring article after article about the engine and how to hop it up. It really does make the original small-block engine look weak, by comparison. A supercharged version of it is being sold in the new Corvettes and Cadillac CTS-V models. I think they're something like 558 horsepower...
