How do i tell a 340 crank from a 360 by looking at it? Any numbers on the crank or tell tell signs?

The factory 360 cranks I've seen have "360" cast into one of the counterweights. Most of the 340s used a forged crank, but the late 1972 and 1973 340s used the same crank as the 318 (same casting number). I'm sure they were balanced differently than the 318 crank. What is the casting number on the crank?
Measure the main journal:
340 will be 2.51 and a 360 will be 2.81
