I saw this listed on eBay. This is a forged steel crank and I mistakenly wondered IF it was a re-worked little y-block 292 HD truck piece. It's not!
Here's the info. that Dale sent me that may help someone who is working on one of this species.
Here's a link to the listing...

It is most likely from a truck.
According to my spec's this is for a 332 "Y" block.
The stock sizes are:
332 "Y" block rod journal size is 2.248 and mains are 2.623, engine bore of 3.800.
292 "Y" block rod journal size is 2.188 and mains are 2.4980, engine bore of 3.7500
312 "Y" block has rod journals 2.188 mains 2.623, engine bore of 3.800
332 "FE" style has rod journals 2.438 mains 2.748, engine bore 4.00
Hope this helps
