CKW could be a base 4-Speed engine from 72, or an L48 4-Speed engine from 76. 76 seems more likely, but you'll want to check for a casting date (I think V1105 is Flint, November 5, but no year).

The 6 before the S in the partial VIN would correspond to 1976 in a standard VIN, but I'm not sure how partial VINs work. Is that an L before the 6S? The VIN of the 1976 car it may have come out of would have been:
1Z37L6S412055

I honestly cant tell what that it before the 6S...It looks like a 1...but a different font than the other 1 ....I have pretty much come to the same conclusion....its nothing important, was the engine in my truck, just have it sitting around
