Bore and stroke will be different.
Crankcases for the 93 are bored larger for the 3 5/8" bore cylinders, past that, they are the same.
Flywheels are different stroke but they both share the same shafts, crank pins, bearings and rods.

the main differences are flywheels, pistons, rings and cylinders.
