I personally have an sn92 on my GTA, so I thought Id intervein. Youll get more from the sn92 than from a set of afr heads. they will work great with stock heads. There are much better superchargers out there but for the money you cant beat a used sn series paxton. Your looking at 6-8 psi on a 305, 5-6 on a 350, and 2-4 on a 383 depending on pulley setup.Only drawback is a 39k rpm max
