The old engine made 807 under conditions that were close to optimum, when I redynoed it under similar conditions (hot weather and humidity it made about 760 peak and 640 lb/ft.
Head flow is 380 at .800 don't know about .600, ex about 265 the engine is still 498 cid. The big difference is it pulls all the way out the back door where the old one fell off dramatically above 7600. I won't do this but Kinetics said an 8500 shift point would be about right. We took 5 pounds out of the crank and lightened the intake valves (titanium in and ex) along with much better valve springs. I wanted 400 cfm but we could not get there with out sliding the heads over ala Barry R. and I did not want too redo headers and intake so we stopped here. It should be a real animal in the car, the old one was scary on 7 cylinders.
