Nope!!
68 to 72 all the same.
73 to 76 some with, some without provision for clutch pivot hole.
455 in a boat are just engines from the assembly line.
boat company's bought them by the hundreds at a time.

There were apparently some "L" casting blocks used in marine applications. I've never personally seen one and frankly I don't know how they differ from the FA blocks. Gene is correct, however. Nearly all marine motors were virtually identical to car motors.
