Hmm, I would have expected more from a combo like that. Wide ports, a dominator, and a much larger camshaft than dad uses, not to mention it's a bigger engine.
Dad is using standard Edelbrock round port heads, the old style with bathtub chambers, his solid roller was smaller on duration at 269/279 @ .050 but with .436/.441 lobes, and an old 950cfm 4150 HP carb that I set up years ago. He made 724hp and 764tq and we never actually found the high peak tq numbers, Tony wasn't starting the pulls until 4500 where peak torque was already falling.
