427 small-block stroker, crankshaft dyno HP 485, 505 lb. torque, Tremec TKO 5-speed.
Nice car and that's a great motor. I have one in my Mach 1. My car scoots, your's should be a rocket.
Mine runs an Edelbrock Pro-Flow 4 that was a big improvement all the way around over the original carb/manifold combo.
