Is a Chrysler Marine 318 block the same as an automotive 318 block?

I ask because I just bought a 66 owens 30' cabin cruiser with twin 318's (obviously). The previous owner said that her port motor had a blown head gasket, and when I fired that motor this weekend I heard a rod knocking HARD! (big surprise) I have paid through the teeth a few times for rebuilds before and have decided I'll just do a swap considering it fired right up and the valves were seating nicely on both banks.

The 318 out of an RV is the same setup as the boat motor/ except for the head gaskets. It may have the coolant running under the carb for carb heat-not the cross flow exhaust and blocker valve. Otherwise you will need the marine heads and intake manifold. The rotation would be a concern, but your marine cam will slip right into the RV engine as well as the reverse rotation ignition. You will -as noted- need the brass freeze plugs. If none of this shows up, you may have an engine that was replaced with a car engine. The car engine was physically lighter. So wouldn't hold up to salt as long as the RV/truck/marine block. Also it may have had nylon covered timing gears- which should be tossed in favor of double row chain.
