    saltwater 5.0 weak points

    Even the dry joint manifolds fail in salt water taking out the motor. Intake manifold and heads can rot thru Having twins, my guess this was a moored boat? If you got it cheap enough, throw two 350 short blocks in there and add heat exhangers

    1985 4.3l v6 mercruiser piston rings

    measure the bores with a bore gauge. you will need more than just the rings unless the block was brand new sitting on a shelf in a time capsule. if it has any hours on it, the bores are no longer round and will be tapered. this means that you will require a minimum of a 0.010 oversized...
