318 marine motors?

My grandpa had a 1966 house boat with one old style (1965) 318 (bought it back in '70-'71).......it always ran great but one of the heads cracked. Got another head for it. It definitely had that boat moving pretty dam fast8) I wish he still had it but he had to sell it 6 or 7 years ago because the price of gas was getting ridiculous. He loved that boat, my father loved that boat and I loved that boat. He sold it to Sea Tow (they work along the Hudson River) and I heard that there using it as an office. At least they didn't scrap it:cheers:

*heads didn't crack, they corroded away from the salt water*
