Heads heavily ported on gt500, it would lose a lot of power at 2000rpm then ramp up higher numbers than before by 2750rpm (much like a voodoo mill needs to come on cam then jumps up 50-75whp/wtq at 3500). It’d probably be a loss of 50wtq down low and a gain of 100whp uptop repullied for 15psi again. I was way off and knew it while I typed that. I saw a picture on your profile of some soldiers, thanks for yours and your family’s/squads sacrifices. I assumed you were a troll and was wrong. Half the stuff I threw out was semi sarcastic mouth foaming.
