I have a 460 Bored .06 with a mild cam, D0VE heads, Cast Iron SCJ intake. Bought the boat and it had a nice Pro Systems 780 cfm custom carb with 73 Pri 73 Sec jets. Only problem is the Pro System is an automotive carb and I have an engine hatch. I picked up a Quick Fuel 850 Marine and am wondering how much should I bump up jets to make up for the CFM gain?
