Ok I have done some research and I think I have most of the mods planned out but not quite.

I was thinkin speed daddy headers with no cat no rear 02 and a cutout with stock catback.

auto lite 104s and 160 tstat

I already have a homemade intake

A PCM(not sure exactly which one)

Would this be enuf to run a 3.3 or even a 3.25 pulley?

About how much power would this setup make on the motor?

This is an 04 impala ss btw
