What do you think this combo would make?

496 big block
10:1 comp
850 holley
Weiand Stealth
781 heads with 2.19 and 1.88 valves, bowls blended, garage porting job
.590 lift cam with 242 at .050
Must fit under stock flat hood.
Any ideas on what it might crank out?

525 if a flat tappet cam ; 550 if a roller

Think there'd be any difference if I use a Eddy Performer RPM? I could use either one....doesn't exactly matter.

I have a 496 Stroker in My camaro SS with that Combination EXCEPT the static ratio is 9.75 , and it has a roller cam It made 585 ft lbs of tourqe on the Dyno and 565 With an EDLEBROCK Dual Plane performer RPM manifold. 850 DP holley on 100 Octane. I lost 30 HP when I switced to the Dual plane manifold But I wanted to use the Stock hood.

Re: What do you think this combo would make?

OEM heads do not like single pattern cams. The exhaust ports need help and this comes from more duration on the exhaust lobe. I would feel it should make about 525 or so.
