I'm pretty sure the shotgun ford pic I posted is an old Lavey, I thought Uncle would enjoy seeing THAT combo since he is a Lavey guy PLUS the earlier questions/comments about "FERDS in marine applications"...
You want to start with the exhaust, and then move on to all the front mount accessories like water pump, power steering, hyd pump for the O/D, bell housing to O/D, drive hub, and drive system for the accessories, etc etc. Its not the engine itself that makes a marine engine, its all the shit you have to hook to it.
A lot of Buicks & Caddys were used in the 60s. Ever seen a set of offshore type manifolds for an outdrive for them. They were "marine" engines.

Stop the goof ball shit Bruce. Show me you are smarter than this.
