A lot also depends on the propeller. I don't know much about the Revmaster, but expect that it will perform about the same as the Aerovee which has the same displacement.
I'd expect climb rates around 800fpm with a 200 lb pilot and around 450fpm at gross weight at 75mph. If your propeller spins faster than ~2850rpm at that speed you'll probably climb a bit faster.
True airspeed at wide open throttle will probably be in the range of 125-145mph depending on the propeller.
