A lot depends on your cam choice. My buddy just let me know they finally dyno'd a 512 they were building which was very similar to mine. It had edelbrock rpm heads and intake and one step smaller comp hydraulic roller 230/236. It made 550 HP and 660 torque, and was already over 600 ft/lbs at 2500 rpm. Don't have any more details yet, but that is some serious torque.
