Stovebold6, looking at your cam sheet, I'd say that's a pretty good cam for pulling at around 2600-2800 RPM. My Crower has split timing advanced 4 deg and 220deg duration at 0.050 and the fire starts to die below about 2600. If I had it to do over again I'd cut the intake duration about 10deg and retard the exhaust timing a little to keep the exhaust manifold and pipes a little cooler, also less noise.
