[RUSTYNTABATHA]

Your going to have to be very carful when building engines that out of the norm for a boat. your cooling capacity is reduced on boats due to engine enclosure and open or closed water systems. The hot rod motors you put in a car are not the same as the hot rod marine engines. My father-in-law built a 383 stroker for a searay and i tryed to tell him to call in for outside help, but son-in-laws opinions arn't much good apparently...... he should of asked for help.. you can't use standerd rv cams in marine aplications. Ask for as much imput as you can get from marine mechanics. Remember no is always free.
