Removing paint from my base 327/210 air cleaner and found on the inside of the air cleaner near the carb opening, is the following aqua colored stampings 335 7 2 . I assume 335th day of 1967 but not sure what the 2 is. Has anyone else observed the same stampings?

2nd shift? I will look at mine.

Usually a A/B or 1/2 is day shift or night shift. cool find.
