13.5:1 compression, long stroke, big heads, solid roller cam, Dominator carb...well north of 750HP and probably the torque to match.

It would be a waste to build it on a 4" bore block... 4.125 or 4.155 bore.

750hp @ 7400
595ft/lbs @ 6000

Too many variables.

What's the bore? What's the cam specs? What do the heads flow? Has intake been prepped? Whose dyno?

Your question can't be answered as is.

North of 600, maybe close to 7. Don't know how they get 750hp out of those heads, suspect afr225 or similar.
