Burt, Are you a ski racer? I am seriously considering putting together a low compression (8.0:1) 572 short block and putting a V-drive oil pan on it. I have been very impressed by the performance claims of the V-drive ski racer type boats and if the claims are true I want one!!! I really like the 21 Schiada River Cruiser with full pleasure boat interior. I know 1100 HP on pump gas is attainable with a blown 572 if it is done right. Turbos are real cool too, but as you stated these motors are high dollar to build and from what I have heard require race fuel???? Anyway what can you tell me about the 21 Schiada? How will it run with 1100 HP? Will it do 100 on radar? I love the idea of getting away from the Bravo outdrive and getting into something that has a "bullett proof driveline" so some serious torque, power, and RPM can be run without any worries. Any info would be appreciated.
