Get the stock tb ported. Otherwise go the FAST 90 route.

Yes, nicely ported stocker with a LS6 intake or after internal mods(heads/cam) go FAST 90/90. Im still a fan of the ported stock 75mm

I just switched to a PTM, but I will say that the stocker that I got, which was ported by Bo, worked like a champ and looked good to.
