Holley Carb 3367

[John F.]

I'm looking at a Holley 3367 for a 66 Coupe 300 HP. The date stamp on the carb is 0586. All the other original carbs I've seen have 3 digit stamps. Additionally, the last digit should represent the week of the month manufactured? Try as I may I don't see how you have a carb built in the 6th week of any month. Am I missing something here?

Any idea how this would be treated in judging?

As a service replacement with a deduction for an incorrect date.

John -

After 1972, Holley changed to a 4-digit Julian date format; the first three are the Julian date, and the fourth is the year. 0586 is the 58th day of 1976 (or 86) on a service replacement carburetor.
