best intake/cams on npi motor w/ stock internals

Like the title says, what's the best intake and cams one can run on an npi motor w/ stock internals. I know there's the PI stuff, but I see guys going with comp cams and the works on some npi motors. Oh and remember this is on the npi heads, prolly ported, to leave room for a blower.

If you're adding a blower, I'd worry less about the cams and more about the hypercraptic pistons. First detonation will leave you with a lesson in the fine art of motor rebuilding...

Having said that, blower cams are different from NA cams. Less overlap will help prevent blowing boost out the exhaust valve. So if you're going to run a blower, get a blower specific cam for best power. On the other hand, the blower cam's minimal overlap will hurt power on an NA engine.

The stock hypereutectic pistons are prone to broken ring lands when experiencing detonation...thus a lesson in rebuilding a short block!!!
