Hey guys, my friend has a 99 GT 5spd, 373's CAI, plenum throttle body, underdrive pulleys. I have basically stock, just a PI intake and K&N filter. I just got some heads i will be porting out, with hopefully some comp cams 262s. Oh I will try to do Long Tubes while i have the motor apart also. Is this enough that wipe that grin off his uptight a$$? He is always putting down NPI cars. If this isnt enough, what other mods should i get? Thanks
