Dynosim needed today

Hey guys, i'm in iraq about to start ordering parts for my 383 . Scat 9000 crank,5140 rods(5.7),forged -5cc dishes. Dart pro 1 platinum 215cc heads(2.05/1.60) with an edelbrock air gap rpm intake that i already own. (do i need single plane instead? ) It's gonna be a solid lift cam(290AS-14) with 1.6 roller rockers and a 750dp HP holley. 1 5/8 headers(shorties). I need to find out what kinda power i'm lookin at vs how much i want. Lookin for over 500 at the crank w/out nitrous . I already have a 150 top shot NOS kit if that helps any. It's goin in my blazer but i don't care at all about driveability cause i know there are sacrafices when going for streetable high horsepower in these wonderful SBC's vs the new LSX engines. I'm 24 now but i still prefer old muscle for some reason, maybe cause that's just what i was raised around. Live Long GEN I SBC!!!!!!!

This is what you'll need to get an 'accurate' estimation:

Rod Length
Cylinder head flow, intake and exhaust 0.100" through 0.700" or whatever the mfg gives for range
Intake valve diameter
Exhaust valve diameter
Static compression ratio
CFM, type of induction (2-bbl, 4-bbl, TBI, TPI)
Intake manifold type, mfg (single 4-bbl, two 4-bbl, one 2-bbl, three 2-bbl, individual runner Weber, mechanical fuel injection, low-rise, high-rise, tunnel ram, dual-plane, single-plane, part no. if you have it.
Exhaust system (be specific, primary tube size if long-tube headers)
I have quite a library of CompCams (give me part number, not grind number) in my files, but if you are using another mfg, I'll need type (flat, roller, solid, hyd.), intake valve lift, exhaust valve lift and the following timing info and at what tappet lift the info is valid...(0.006", 0.050") I can calculate from 0.020" if I'm given enough information, but again, that takes my time.
Intake opens ______BTDC
Intake closes ______ABDC
Exhaust opens______BBDC
Exhaust closes______ATDC
