58mm turbos on a ADM built 427 with ported
LS3 Heads and small Ls9 cam.
At a modest 14 psi they layed a tire frying
870 rwhp in a 1967 Camaro (yes 67)
Ill post the graph up soon as I'm not near the Dyno.
Wow. That's pretty darn impressive for a stock cam. It would probably gain 75-100hp at the same boost with just a cam swap.
