Default Block Identification help

Distant relative had a death in the family, and they have some C1 parts. There is a 519 block that I didn't get a chance to see casting date. Pad stamp has 1107103 (VIN) and F0323CU. Any ideas on what this came out of?

You don't need the casting date to determine the year the engine came from, the VIN tells you the year. The first "1" in the VIN stamp identifies it as coming out of a 1961 Corvette. "1". is the year "107103" the sequence number meaning the engine was originally installed in the 7103rd 1961 Corvette built.

Not in C-1 registry, no NMVTIS record found. But at least we know what it used to be.
