415HP from 318ci IS POSSABLE!!

Imagine this with 1.78 intake valves and 1.50 exh. valves. High velocity and a well designed port makes it work very well. With the engine making 501 HP on gas the head flow shows 243.2 cfm's, but the heads actually flow 230 cfm's. On alcohol the HP go's to 535 HP and the head cfm's would be 259.7 so even though the heads really flow 230 the heads or should I say the engine can be tricked to thinking that the heads actually flow 12% better. The lighter the parts and the better the engine is machined the more you can trick the numbers, roller cams have a big influence on this also.

You can trick a engine up to 30% more than the heads actually flow. This is where the science and the art of building engines comes into play. This just happeneds to be something that I really like to do. Along with tuning them to perfection.
