Big block Chevy. Looks like a forged crank needs a good clean up and turning. Probably worth $300-400

 

Bump being told this maybe a mopar 440 crank. Anyone help confirm?

 

Maybe measure the journals as that should help ID it.

 

Can't find my micrometer unfortunately

 

Snout is not bbchevy. Maybe bbchrysler

 

So wrap a string around a journal, measure the length with a ruler, and calculate the diameter.
It's really not so hard, and if you really want to know what it is, you need to post some data that helps people identify it.

 

Rods are 2.38 and mains are 2.70 if this helps anyone I'd this crank. This is with tape and a tape measure and divide by π
