+ ∞. 375 rwhp from nothing but heads and cams? Pa-leeze. That's more than a stock Terminator makes. And it's got 4 valve heads and a blower. Maybe a car did make 375 (or 350, or whatever) on a particular day on a particular dyno with a particular correction factor, but I bet it won't run much (if any) faster at the track than a ported PI/cammed/full bolt on 2 valve (making 325) does.
