Hi I'm new this this site. So I'm about to jump into a complete build of a 2002 GTP. I'm not going to get completely wild. I'm thinking of a cam, lifters. springs and retainers, pushrods, timing set, CAI, 3.25 pulley, headers, u-bend delete, improving flow in and out with mild port work, PCM up grade. Now I have looked at a few different suppliers. For the people that have done this, whom is the best and the worst, I have seen prices vary for the same products, also what about balance shaft removal, also is there a different MAF for modified engines. Any info would greatly be accepted, Mike.
