Not Ranked
Rick,
I feel like I'm stealing rnocobra's thread here, but it has always been a burning question in my mind about the sizing of heads for the small block/large cube engines. As I stated before the biggest small block heads aren't near the same flow as the smallest big block heads. You can't get the big numbers because of the valve size restrictions. So, does that mean that we're not getting the full advantage of 427 cubic inches when we punch out the small blocks? I'd think that a 427 big block would out perform a 427 small block simply because of it's ability to put more fuel/air mix through the cylinders (all other things being the same). I'm no expert here either, but I'd sure like to here an explanation from some one who has experimented under lab conditions. I remember when I built the engine for my Unique a friend was pushing me to build the combustion chamber/piston according to a design by Endyne. This would give me a compression ratio of 11.7/1. I didn't think it would work but I did it anyway and guess what? It runs great on 93 octane pump gas! The things I don't know would fill an encyclopedia!
