Mike, my motor (from memory) turned 436 hp at 5500 and was still climbing...torque was 501 @ about 3700 (I'll verify), but that was with std rockers, exhaust vented into the dyno room (they couldn't hook the exhaust onto the sidepipes), a set of truck pulleys, and the carb was out of whack a bit. I'm guessing that with the underdrive pulleys and roller rockers, and reworking my carb, it's putting out an easy 450+ HP, 500+ lb-ft of torque, under 6000 rpm, and very streetable.
Good luck
