I have an 01 quad cab that I restored, yep, restored for a daily driver. It has a decent running 360 and an auto. I have already put a cold air intake and exhaust on it and ported and polished the throttle body. I'm not terribly familiar with these engines so I was wondering if anyone could give me some tips on where to look for a few more hp without hurting drivability. I have about 2k to blow on it and dont really want to go the header route so any tips would be greatly appreciated.
