I have a 18' jet boat with a 455 olds, HEI, Torker intake, 750 cfm Holley vac. secondarys,O.T. headers, and a stock cam!!! Could use some advice on which cam I should be running in this boat. I use the boat for general fun, water skiing, and the ocasional freindly race. The motor has very few hours on it, comp. ratio is probobly 9:1. Thanks for any advice.
