Do you have the full cam specs? Assuming you will have a good exhaust system, I bet you will be around 575hp and 600 ftlbs. That is assuming a hydraulic flat tappet cam with mid .500 lift. If you got a cam with .600+ lift, I think as much as ~650 hp may be possible. I think the motor below is a good one to compare to.

I am pretty sure I found the cam for the engine below:
236 246 @.050 .553 .571 lift

540 hp 509:

Ill bet The cam is very close to yours. This engine has a little less compression and the heads are not ported.
