Those will work, but due to the 550 lift they won't be optimal, and might require certain modifications. The 268's would be a better choice.

RyanK

could you link me to the 268's? how would they sound and preform what gains am i looking at

you would need to get offset spring retainers and new springs to use .55 lift cams. npi cams bind at about .53 lift. there was a guy on here earlier (i almost bought em) that was selling a pair of brand new 268 comp cams. these are a npi cam and will have that great cammy sound. look in the for sale section.

I already did. Check out post #10 again.

They will have a light chop at idle if you have a decent exhaust system, and will probably give you 20-30 hp.

Why not just look for a used PI upgrade package.. Someone's gotta be selling the heads/cams/intake...

MRT!!! I CANT BELIEVE YOU!!! You get the opportune time to talk up Bullet racing cams for the NPI motor and you didnt take it!!! lol just thought i'd bust your ***** since every cams thread you usually say something about bullet racing cams and they are one of the few that actually do offer NPI specific cams. Linky for OP:
