I have a fresh 39-41 Merc block with the factory relief. Stock cam, but bored to 3-5/16 and a Merc 4" crank. Question is what flywheel can be used and can I use the 2 piece 59A style pan? Can I use the 8ba flywheel or will it need to be the one that is the same style but a little thicker. No idea what the motor will be going into. I want the motor as complete as possible before selling. Thanks and Merry Christmas to all. Bill
