Dont forget that you want both engines to be identical. So you will have to buy another kit. When I ordered my engines (US engine as we spoke of earlier) They sugested the performer intake and a 750 cfm carb. Thats what they used to produce the advertised 420 hp. As for the carbs, Ive always been told don't use a street carb for marine, but I'm sure others have more knowledge in this area.

once you get into them your going to find (if its a salt water boat) a whole bunch of nasty rust! my suggeation is to find a pair of big blocks already done..the 330hp have tiny rods and cast crank the first thing to go will be the rods,your going to end up beating or even braking the pistons apart to get them out..i had the same thing happen to a engine in one of my boats and opted to find a good set of 502's i went through..

check offshoreonly and some other places for full reman engines. you would be surprised... the market sucks so bad that I have seen engines fully built for less than the cost of parts.
