How are you going to cool it? Lake water or contained coolant and RAD?

Kind of a combination of both. I am going to be making a heat exchanger. So it will be closed loop cooling for the engine then use lake water off the jet to cool the exchanger. I will be starting on it this afternoon so i will be posting pics up hopefully tomorrow.

Looking awsome. I wish I had the time for a project like this. Can't wait to see it under its own power

Interesting heat exchanger, are the upper outlets for the coolant, and the lowers for water?
if so, what is the side port for?

You are exactly right. The uppers are the in and out for the engine coolant. Lake water will pump in the bottom and out the top port. The second bottom port is for drain or garden hose hookup.
