Well, I'll throw in a pennys worth of thoughts. You left out a couple things such as intake, carb, and headers which are pretty important when taking a guess. But, with a dualplane intake like a Edelbrock RPM, open headers, and a 750-850 carb. I'd throw my money down somewhere around 500hp, and maybe 525-550 ft.lbs. Granted thats assuming alot.
