Good luck
I heard about the marine engine application - and yesterday found that the well-sorted top oiler that I earlier referred to was previously used in a V-drive boat and its a casting number is C5AE-A. The current owner believed the engine sat backwards in the boat and was crank drive.

Not sure exactly what that means, other than it was suitable enough for him to build up for his car.
