OK here is what the Gonkulator is getting for this torque monster (cam is 7 degrees advanced so I'm calling it a torque monster)
I'm also assuming the same 2" headers your dyno usually runs? Torq is sensitive to the whole exhaust setup, power not so much.
SAE GROSS, 60F 29.92 dry air
Torq 496 at 4800
Powr 574 at 6900
Same except retarded 4 degrees to 114 LSA, 111 ICL
Torq 501 at 4900 +5
Powr 593 at 7000 +19
I don't know how to "uncorrect" SAE gross numbers without guessing the weather - I have your altitude at 750 ft, so will guess a "winter" correction factor of say 1.04. So using that 107 ICL cam, knocking 4% off these numbers gives:
Torq 477 at 4800
Powr 552 at 6900
So these last numbers are my guess per the rules. If I win those rockers I'll need a lot bigger cam, and then heads that can use that extra lift, and then rods that will handle the rpm, and bigger exhaust, and electric cutouts, and, oh, too much to handle right now.
Will those rockers work on the Model A Ford? (that was a joke for you young folk out there!)
