Smallblock efficiency or How to have your cake and eat it too

The heads should be something like an EQ Magnum with no more than a 2.02 intake valve size. The heads don't have have to be iron but I happen to believe the iron head CAN be more efficient than aluminum because of thermal efficiency. You have less energy in BTU's escaping the combustion chamber where you want them to expand the Nitrogen in the air/fuel charge. Polish the chambers and port them to get whatever flow is required to hit your HP goal. If I wanted 500HP I would shoot for 240-250 cfm. Keep the port small and fast. Make sure your static comp ratio is somewhere around 10.5-10.7 and target 190-200 cranking compression<<<This is important. Yes it will be important to be on your tune but that comes later and is the fun part. J.Rob
