I lost a 87 5.7 omc this summer due to exhaust risers failing and letting good old lake water back in through the exhaust valves. Anyway, I am looking to purchase a 350 4 bolt long block and change freeze plugs and intake gasket and us existing bolt ons, but dont know which cam to have installed. The motor is in a 28' Sea Ray with twin 350's. I am trying to match the other as closely as I can so I dont have a hugh variance in throttle position. Any help would be greatly appreciated.
Thanks. New to thread but been boating and working on motors for 25+ trs.
