Interesting. I had heard that some of the Mastercraft boats had 351Cs, unfortunately, my searches via Wikipedia have not turned up much information regarding specific engine configurations....
Anyway, I may be totally off base, but 1) it’s an interesting concept, 2) the configuration makes sense, and 3) Gary Hall certainly was the kind of guy who would agree that reuse was a good strategy! But I will let the experts (like yourself) guide me!
