How much HP will it deliver?

Yeah, I'm thinking along the lines with Wild&Crazy here......except I don't know if the valve-to-piston clearance would allow over .500 lift.....better be sure about that one. But that cam you've got doesn't sound too bad......I'm thinking 375 HP......hell, if it's going to be a 371 now, that's only 1 HP per cube!......with 2.02's and some porting? Come on, that really shouldn't be too hard, to me. Oh yeah, make sure you get the Air Gap Performer.

Hell, you might hit 410!!

Is this the intake you are refering to?

that seems to have a higher range of rpm than my performer intake. It`s probably not a bad idea changing it.
This will not be a street driven vehicle (formula offroad like this):

so it doesn`t have to be "streetable"
what camshaft would you recomend for a high rpm engine without worrying about valve piston clearence?
