My source is George Anderson, owner Gessford Machine Shop. Recent award winner for the best machine shop in the Nation and FE expert.

HOWEVER, I don't think it's as simple as it may sound. For MY 427 FE at 100% volumetric efficiency and 12.5 to 1 C.R. the "math" indicates 600 plus horse at 6000 rpm. The dyno came up with 667 horse. Dropping THAT engines C.R. "mathmatically" reduced the horses by about 150.

Does that relation hold true for small blocks and engines under 400-500 horse? I don't know, perhaps not. BIG engines moving a LOT of air (intake/exhaust cfm ) are more sensitive to just about anything. My sidepipes drop a 100 horses off for instance. You couldn't say every Cobra looses a 100 horse from their sidepipes.
