Visible difference between 2.2 and 2.4/2.7 crankshaft
 

I have a 930/52 motor apart that has been a mix and match of various parts, including a 6 bolt crank. I'm trying to confirm what the crankshaft is though, 2.2 or 2.4/2.7.
Is there a way for a layman to confirm which crank is which by just looking at the crank?

2.2 cranks are 66mm stroke whilst 2.4/2.7 are 70.4mm

The easiest way to tell the difference between a 2.0/2.2 crank and a 2.4/2.7 crank is by looking at the flywheel flange. They all have six flywheel bolt holes but the 2.0/2.2 flange has two oil galley holes and the 2.4/2.7 crank only has one.
This makes identifying the crank easy even when the crank is in the case.
Just remove the flywheel.

2.0/2.2

On the 2.4 and 2.2 sitting together, the drill holes for the rod oiling on the 2.4 are more than twice the size of the 2.2.

That's easy enough. Thanks fellas!
