What size headers??

Hey all, I've just ordered a set of 2" ARH headers, and am now wondering if perhaps those are to big for my application and I'd be better off with 1 7/8's instead.

My setup is a forged 347 with 14lbs of boost, when it was last on the dyno it made 720rwhp, with an ill suited cam. As a part of this build up, I'll be swapping in one of the ECS blower cams and hoping to land North of 800rwhp.

Thoughts??

at that power level, you'll be fine. if you were stock with low boost, i'd recommend 1 3/4

Thanks... engine is out for a rebuild already so hopefully it will make things go smoothly.

Anyone installed these that has any pointers? Any wiring need to be extended or rerouted?

Just hope you dont have to pull your A/C pipe and have it redone. I did on my KOOKS headers. Some said they had to also on the these and others have said didnt have too... You will like them anyway...
