how rare is a 3738072 crankshaft in a 1962 409

[409forever]

I have a 62 QB 409 that was assembled in Feb 62 the crankshaft has the casting # 3738072 which appears to be 61 don't see stamping from machine work done
Was there some crossover between 61 and 62 in parts that may have been used in the manufacture at the Tonawawda Plant
Thanks

Ive seen 072 crankshafts in both 61 and 62 409 motors, I dont think this is too unusual

I kinda figured that may be the case just carryover stock from 61
I have checked every other part matches the build date
Thanks

Yep, I bet I’ve had more 072’s than any others.
