I gotta go with around 800 hp max. I have a very similar setup and I made 765 hp at 5500 with 8lbs boost. You will not be able to run that much boost due to your higher base compression ratio. I am at 8-1 comp. I did make one pull to 6000 rpm and it made 825 hp, but I would never run it that way so we backed down the limiter. My intake is all stock. I modified the stock fuel rail and have 1200 cfm Whipple throttle bodies.
