First of all I want to say thank you everyone in this forum for the solid advice iv got in the past from here. Shoutout to Scotty if he's still on here! Right now I'm looking at getting a cam for my 02 Gtp that's on a 3.2 gen 3 with an ssic headers etc.. and I'm looking at going with maybe an XP cam from zzp and was wondering what kind of modifications are really needed to run one valvetrain wise. I'm still rocking stock heads completely. Any advice it's greatly appreciated. My goal is a 2.9 pulley with adding on e85 if It came to that.
