01 3.1 underdrive/super

[sweetgp07]

Alright, i've got a 2001 grand prix 3.1L. Ive been looking into underdrive pullies to get a bit more power out of it, but I havent found anyone who makes them. If anyone knows who would have them, that would be wonderful because I'm confident we can do the work, I just need the parts

Also, I may have the oppertunity to get a l67 s/c very soon, and I know it's made for the 3.8L, but is it possible to make it fit the 3.1? and how much work would it be? my guess is new pullies all together, intake manifold, plus a bolt on but that seems way too simple...
