415 HP@ 6000RPM = 405 TRQ@4500RPM
It holds steady over 400HP from 5500rpm to 6500rpm.

I put in the flow specs for Iron Eagle heads, 2.02/1.6, 9.5 comp.
Lingenfelter Hyd. FT cam, 212/224, .488/.496 with 1.6 roller tip rockers
Dual plane intake, 600cfm carb (Edelbrocks)
Small tube headers with mufflers

Since its a computer simulation, Id guess the actual might be around 25hp and torque less? Seem about right for those components? I'm also gonna be using a 100shot of nitrous.

 

Actually since you have flow numbers, it should be pretty close. The more accurate information you can enter, the more accurate the results are.

Oh course real world is always different. Putting an engine on a dyno is only good for tuning. What it actually does on the street or strip once it's in a car isn't usually what you expect.

 

Not sure what specs you plugged in but I got just over 350HP attempting to duplicate your simulation.

I assumed a 355ci engine and used the Chevy Hi Performance head flow test numbers for the Iron Eagles. The cam I did per the specs you listed and assumed a 110* LSA on a 106* ICL.

That's an awful small cam to be getting well over 1 HP/ci with.

 

I might go with a bigger cam. I want to make the most power with out having to rev past 6000rpm though
