Desktop Dyno Help
Hey all you guys/gals with a desktop dyno, could you help me out? Just wanting a guess at this simple street combo:
Ford 460 With 9.1:1 C/R, D3VE heads (stock valves, mild porting), dual exhaust, no headers, cam specs(Comp Cams 34-226-4): .484/.510 gross lift, with 211/233 duration @.05", Lobe Sep 110. Has Holley 750, with Edelbrock Performer RPM intake, Stock Duraspark II ignition. Anything I forgot?
Thanks,
Rad

Lookes like a solid build except for the headers.
DD prediction with factory exhaust manifolds
372 HP @ 5000
442 lb-ft torque @ 3500
DD prediction after swapping to headers (1-3/4 primaries, 2.5" collectors)
444 HP @ 5500
493 lb-ft torque @ 4000
That's a gain of 72 HP and 51 lb-ft torque just by bolting on a set of headers. In terms of HP per dollar, it doesn't get much cheaper than that.
