I have a 98 GT that is stock. I just purchased a 2004 2v 4.6 w/ 6000 miles that i am going to drop in my 98. before I do the swap i am going to p&p the heads and change the cams (don't know to what yet). Not sure what exhaust, or other bolt ons I should buy yet, still doing my homework... Any suggestions would be appriciated. Thinking about a supercharger as well in the future. My question is how much gain should I see from the heads and cams? i know it will depend on what other bolt ons I go with, but i just want a ballpark. Thanks for your help!
