We do a lot of different combo's based on the goals and setup. But for a NA car that does want to maintain a good amount of drivability we have a great setup and even on our junk 91 octane will crack 500 rwhp. We use our defibrillator cam, AI ported stock heads, and follow it up w/ either our ported LS3 manifold and TB combo or do a fast 102/102 setup or take it a bit further and have us port the fast too. Here are some idle clips of the cam btw.
