I don't get anything out of that. Are there any numbers stamped on the engine ID pad on the passenger's side at the front that would be just behind the alternator? It's part of the head deck surface on the passenger's side at the front.

Maybe take some close up pictures of the block. That's where the answers are.

No casting number on the driver side of the block? Should be 7 digits.
