By I/H/E I meant Intake, Header, and Exhaust. They are a good platform to mod, hell if I had the money I'd buy one and build it. I'm just commenting on if you don't really break into the motor (such as heads/cam/bottom end) they aren't that great and everyone that I have seen around here (KC) could not break out of 14's and the fastest stock cam/head/bottom end 5.0 Fox I saw threw down low 13's on the bottle and DR's. Hope I didn't hit a soft spot with you just saying my opinion about them...
