I am in the process of putting the engine back together for my 77 hallett mini day cruiser jet boat. It had a 460 Hardin marine/Gale banks turbo package. It was the typical all iron 460 with the Cobra jet style intake with regular port d3ve heads like most were. I want to upgrade to an aluminum intake. New engine is a 9to1 with slightly worked d3ve heads, comp cams jet boat cam. That's about it for the engine. I just don't want to put that heavy intake back on, and want to build a little extra power if I can. The banks turbo kit is the stage 1 with single carb, small intercooler, and only about 5lbs of boost. What are your guys recommendations?
