Never did dyno that engine, I would imagine it was in the 400 hp range, probably around 430 torque. With the Edelbrock Victor Jr. heads on a 501 stroker with a Dominator carb, friend of mine has 500 hp, 570 torque. Runs 10.90's in the car. Has some bugs to work out of it yet, when it's tuned right, should go 10.50's
