i know its not a svt question but it is an sn95 question lol. im thinking about buying a 98 gt and i want to do a pi head and intake swap on it. i was thinking about comp cams stage II XE270AH cams instead of the pi cams, is there a serial number i could look at to make sure im buying the right heads and not npi? could u of those who know or have done the swap please tell me what else i would need to complete the swap correctly. thanks guys! oh also what would the rwhp/rwtq be with that set up? thanks again look forward to getting into the 4.6 mod game.
