71 Dart / 5.9 Magnum / Procharger

Looking good! What is the upper power potential on one of those pro chargers?
Are you still running the same converter as the n/a setup?
I'm running the P-1SC Procharger. On 10 lbs of boost I hope to make 630 crank HP. One of these days I'll put in forged rotating assembly the. Turn up the boost with a smaller pulley.

Still running the same 904 transmission and torque converter.
