Without running it on my simulator.... 500+gross I would guess.
Buddy with a 383 and similar parts... mid 10's in a stripped out 70 Nova.
I also think that carb is too small.

What would you recommend for a carb?

Intake/Carb=Edelbrock #2970 (Super-Victor) / Holley 8896-1(4500 CFM)
Compression ratio is "dead-on" @ 10.95 and runs with no problems on 93 Octane @ 34 Degrees total timing. I will add here however, we did the initial test using 110 because it was in the fuel cell. We ran it out and tested on 93. Unit has a .070" quench, .032" P/D, and .038" Head Gasket.
Final numbers=580 HP @ 6400 RPM and 523 Ft.Lbs. @ 5500 RPM. You have to remember this is numbers we delivered the unit at on the weekend. We do have them slightly higher from some more of our own tests, but gave it to the customer at the posted numbers. This one will be returned in 6/7 months to be converted to a "Blown" alcohol unit with only a cam change, the C.R. will remain constant with the blower. (This info is from post a few weeks back). Thanks, Gary in N.Y.
P.S. The photo of the unit installed in the El Camino has the headers in place temporarily, these were his original ones from the 383" unit he removed, but he has ordered 2.000" pipes from "Stahl" I believe.
