How to tell a 289 And 259 cranks apart

[transtarken]

I would like to know how you can tell the differnce between a 289 crankshaft and a 259. I have been offerd by telephone a new 289 crankshaft but he donesnt know if it is a 289 for shure. I have a new 259 crankshaft. If he was located near me we could compare them. Is there numbers or marking to tell them apart. Thank Ken

There must be an easier way to identify, but one can measure from the center of the crankshaft axis to the center of the crank journal axis. The 259 has a 3.25" stroke and the 289 has a 3.625" stroke.

Per John's excellent suggestion, here is info from that website for the 'forging' numbers:
259 1955-1964 (3 1/4" Stroke)
#526831
#526832
#536452
#530081
#1556997

289 1955-64 (3 5/8" Stroke)
#1556444
#180590
#526956 (Same # as Packard)
#537424 (Same # as Packard)
