Guess the horsepower and torque!

How much horsepower and torque do you guys think my engine builder will be able to pull out of my 408 build with the following:

- 4 inch stroke
- Forged dish piston (around 10.5:1 compression ratio)
- A cam around the mid .550 lift range
- An Edelbrock RPM Air Gap intake manifold that is port matched
- A set of Edelbrock 63 cc closed chambered heads
- An Edelbrock Thunder AVS 800 CFM carb
- And a set of TTI 1 5/8" to 1 3/4" step headers and 3 inch exhaust all the way out

Any guesses guys?!
