Too many small block chevy guys would cheap out on the heads reusing springs & values etc. to save a buck, & wonder why they didn't get a screaming little engine! Now that size engine gets twice the power per cubic inch! Who woulda thunk it back in the days of '57 Chevy's! What was that Ford secretaries' car they put on a Falcon frame in '65? I can't remember what that was called! A horsey or pony or something? Some guy name Shelby came along & saved it from the secretaries!
