I put a 97 670 Summit together with my step son. What we need is what size jet size should we start with at 2000ft? Would like to keep the HAC but is willing to take it off if someone can tell me how and could help with jetting from 2,000ft to10,000ft. We don't care if the pipes make or lose HP he likes the sound of them. Plus I had them sitting on the shelf. Thanks!!!

Ill see if I can dig up some old numbers. I had a 96 with oil inj delete, bigger carbs, crank shop twins and a milled head. That sled ripped. I wish I wouldnt of sold it. Those pipes work well with that engine
