Default 1969 Corvette 427 Big Block
Found a block from what appears to be a 427 Big block Corvette. Stamped TI103LM. It does not have a VIN on it though. Instead it is stamped B1504. Any ideas what this is?

LM indicates the 390hp engine. My guess is that B1504 is a rebuilder's code.

You sure it is not T1103LM? Which would indicate a 390hp MT 427 built Nov 3rd 1968

TI103LM works. Alpha Is were often substituted for numeric 1s. Keep in mind, there were two Novembers during the 69 production run.
