Hemi block stamp 2

Guys, recently I posted about a stamp on my Hemi engine bottom pad and mentioned the letters "RM" and unfortunately I was wrong. The pad actually starts with "MN" instead. The question is the same, i.e., what do they mean?

As I stated before, it stands for the marysville engine plant, it has nothing to do with the car it came in. The 426 is obvious, the next four digits are the 10,000 day calendar date, and the next four are a daily sequence number.
