Camshafts, idle quality, driveability and LSA-REAL WORLD EXP and OPINION

RAMM said

Your camshaft choice will be very satisfying. Put them in straight up, your static comp maybe a touch high for a boat and the available fuel on the water. I'd bet your idle vacuum to be somewhere around 16-17" without much difficulty, idling around the docks and outdrive shifting should be a non-issue with a low RPM idle speed you will use. Keep us updated when you dyno them. J.Rob

The GM Vortec marine engines run 9.4 to 1 compression, so that is what I aimed for, making sure I had good .040 quench. Would I be better off going up to a .050 quench and lowering the compression to 9.2? At the fuel docks it's usually 93 and sometimes 89 Octane. I plan on keeping some good Octane boost on board in case it's an issue at unknown docks. I'm running Volvo drives and they use a cone clutch so that should also help with shifting around the docks.
