Here's the question guys and gals- is a 350 chevy engine block and heads from a car the same as a boat 350 except for the add ons like exhaust manifolds, etc? I have asked many people and so far it's at 50/50....somebody has to be wrong....The reason I ask....I can get a rebuilt 350 from the shop for less than a grand and put all the add ons from my existing engine, i think.....OR does a marine 350 have different compression, cams or ? if you know(and not think you know) shoot me an email...Im an engine away from putting this boat in the water in June....Thanks for your advice, gary
