Somewhere in the early 70s (I think 1972) Holley carbs went from a 3 digit date to a 4 digit date. For a 4 digit date code, the first 3 characters represented the Julian date (1 through 366) and the last character represented the year of the decade.
3 digit date codes were prior to about 1972, and I believe the digits were for year, month, week.
