How about a marine/industrial Slant?
Shot peened crank, loose bottom end with high flow oil pump, forged slugs, copper coated rods and glyptal coated block interior. Not to mention stellite valves, rotacaps, and factory double roller timing chain.
That's not quite how it worked.
There was no "Marine/Industrial" slant-6. There were several different versions of the engine for marine service. And there were several different versions of the engine for industrial service. Depending on the exact type of service for which they were intended, they got different pieces and treatments.
The only slant-6 to get Stellite exhaust valves and Rotocaps was the 225-3, which was the heaviest-duty truck/bus engine, not an industrial power unit. The industrial engines all used ordinary passenger car type components. The 225-2 was where the shotpeened crank, double-roller timing chain and sprocket set and polyacrylic valve stem seals started (the 225-3 had these, too.)
Glyptal-coated block? Not according to any piece of factory literature I've seen on the matter, and I've seen a *LOT* of such material. Where'd this info come from? Glyptal block coating is primarily an aftermarket trick.
Forged pistons: Nope, never from the factory.
Copper-coated rods? Think you're thinking of the bronze external water pump that was used in the marine versions. There were no such rods.
"Loose bottom end" you're making up.
"High flow oil pump" was really a high-
volume oil pump.
