Don't get me wrong, the DP intake isn't anything fancy. It' a compromised intake that in basic design, a carb intake.

That being said, I'd only use one on a 426+ CI motor, 240+ @.050 camshaft, 12:1 compression on 93, 2" headers with heads like my eagles. That would be over 550rwhp from a streetable combination, and it would be perfect to run a 250+shot on.

As a matter of fact, that just may be what I build next...but with the shorter intake. It would be way less trouble than the forced induction on my car.
