output
Desktop dyno estimates about 415 ft-lbs @ 4500rpm and 398 HP at 5500rpm. Torque curve is very flat, 368 ft-lb @ 2000rpm. Exactly what I want for a 4x4...a stump puller!
Side note, my dad ran a desktop dyno on his 502 and it was very close to what GM advertised.

Desktop Dyno 2000, its computer software for estimating the horsepower and torque curves based on the specs of the engine components you enter.
Had to do some rework. Found out that you shouldn't use the stock exhaust valve rotators due the added lift of my cam. I'm having to replace them a "anti-rotator" kit. luckily we can do that with out having to take the intake and heads back off. Any of you guys want to keep 'Murphy' at you house for a while?
