I just recently purchased a 02gt. Its my first stang with a 4.6 and dont know much about them. I know everything there is to know about a 5.0, but the 4.6 is a whole diff game. i was wondering what N/A mods i would have to do to run 12's on motor. I have 373's, x-pipe, and flowmasters. feels slow as hell. I hear things about PI heads and cams....does my car have those stock? any help would be appreciated. thanks
