Estimated Power?

I started this project a while ago and put it on hold when I came across a cheap 468 for my IROC. The time has come to get back to my project.

400 bored out to a 409? (.040)


I plan on running:
10.5:1 CR
200cc intake, 2.02/1.6 valves
.594/.594 lift 305/314 duration

Think I can break 520 horses on pump fuel? I'm going to be buying a nice z28/iroc or monte carlo ss roller for the motor when I'm done.
