How too find Crank #s/what is it?
How would I find out what crank I have. I have these #s off the crank 3932442 /NF /6M70 /70 /F277 Them are all the #s that where on the crank. I need to find out what it came out of. I need to buy harmonic balancer. The one I have is the wrong one, TDC don't line up.

This is what i found in the Catalog of V-8 Chevy casting numbers. 3932442 decodes to quite a few vehicles:
1 - '68-81 passenger car, camaro, chevelle or nova with a 350. 2 - '69-85 truck with a 350 3 - '76-85 truck with a 305 4 - '79-82 with a 267 All cranks with that code are cast iron and large journal I think the rest are date codes when it was made.

3932442 is a '69 - '85 cast crankshaft used in 305s and 350s. I would think that is the same crank used in pretty much every two piece rear seal truck 350. There were two different positions used for the timing tabs on the cam covers. Older engines like what came in the '67 - '72 trucks had the tab at about the 2:00 position, and the later model ones had the tab straight up at 12:00. You just need to have the balancer to go with the tab position that you are using. The crankshaft is the same either way.

OK
So if it came in a 305 and 350, a 305 and 350 have the same stroke? So I just need a blancer to match my timing chain cover?
