Well aint no way n hell imma rev my shit past 9.5 anyway. Shit i dont wanna rev it past 8 I make good power with this motor down low. But the cam that with on came with are gay. And if i buy soem stage 2 or 3 cams and the kit u need to handle them. I might as well spend a lil more and go v-tec. Thanks for the info guys im hearing so many different things im losing my mind... I just wanna rev to 8 maybe a lil higher i dont even wanna touch 9...
