Im just saying I agree that 99.9% people should start with a 360, but as to the naysayers that say you can't make power or get E.T's with a 273 I'm sure this will go a long way to prove that wrong, I hate the miss use of the phrase no replacement for displacement. This is with 2 major corks on this engine you probably could add 20hp to every results with a better intake and imagine fully ported heads or notched block and a set of RHS.
