Fleet, the RPM where you reach total advance is going to depend on your cam profile, compression ratio, and a few other factors. The only sure way to determine it is with a dyno, where you can monitor torque and horsepower at different RPM's. Where are you located? I've got the dyno setup in Nashville to give that one a wring-out, if you're anywhere near me. It mounts on a bellhousing, with a standard Chevy clutch, so it's a pretty simple setup. I've had engines of over 700 HP on it so far. Nothing beats a good dyno and a 4-gas exhaust analyzer to get the max performance out of an engine!
