3.8 head swap
have a 97 gtp, my question is can you swap naturally aspirated 3.8 heads to a supercharged 3.8 and would it help or hurt it. im told the supercharged has lower compression. and if it would help would it be enough for the swap?
Changing heads is a big project. If the only reason you're doing it is to improve performance forget it. There are lots of other easier and more effective ways to gain performance. Cold air intake, supercharger pulleys and exhaust all come to mind. Visit ZZ Performance if you need ideas.
