Marine Exhaust Manifolds...

I saw some really cool lookin marine exhaust manifolds for a Chrysler big block engine on FeBay awhile back. Got me to thinking. Can they be used on a rod? Could I somehow plumb them into the cooling system? Excuse my ignorance as I have no clue about anything marine. It looked like the manifolds had inlets and outlets for running water through them for cooling. I was thinking it would be a cool addition.

 

i've used em before , haven't plumed em but i've ran them on rods.

 

You'd probably need a second radiator & electric w/p.
