Estimated Horsepower and Torque?

I'm building the following motor. What would you guess the horsepower and torque specs will be?

351W bored and stroked to 408"

10:1 compression (based upon dished pistons and 60 cc head chambers)

Edelbrock Performer RPM Alum cylinder heads with the larger 2.02" intake valves, 60 cc chambers, 170cc intake runners

Comp Cams full roller rocker arms

Edelbrock Performer RPM Air Gap intake

Holley 750 CFM carb

Superformance headers and side pipe exhaust

Cam specs as follows: Hydraulic Roller: Lift: 510/534, duration at .050 222/232, 114 LC

MSD Pro Billet Street distributor

Milodon Windage tray and 8 quart pan

What's a wild guess on torque and horsepower?
