Can you decode this engine tag to verify what it is?

Guy swears it is the L92. But he also swears it came out of a 2007 silverado Z71. So I don't know which is right. He sent me this picture. Is it possible to decode what it is from the tag? I can barely make out the casting number and google isn't helping me much. Any help would be greatly appreciated.
