WOWZERZ!!! Over 450 Lb/ft of torque from 1000 to 5000 RPM.
I know it's a bit of an "optimistic" program, but holy cow, what a torque bow (can't really call it much of a curve).........
I wonder what a 390, with 9.5 CR and a genuine GT/CJ cam would have with an edelbrock performer intake, edelbrock 600, and flowtech headers.

any one have the specs off a stock cam for 390 4v or 2v ?
i want to run a 100% stock simulation to see what numbers come up , that should give me an idea of how off the program is .

Man I wish it was accurate. 480hp-605ft/lbs would be awesome! Unfortunately real world numbers are more like 450/515. And the peak hp occures at 5100rpm also instead of 4500. The tq bow is pretty accurate just at a higher number. Seems like the dyno reads pretty high on the tq being that the stock 390 shows 450 where as it was rated at 427. It's not too far from stock hp/tq and rpm peaks but most likely gets less accurate the further from stock the specs go.
CR for mine is 9.86:1 btw.
