Holley carb date codes ???

**sixtyeight** · 11-26-2003, 08:35 PM

My brother has a holley carb. that has a C3AF part # with a date code 6B2. My question is how to decode holley date codes? To me it would decode as 6=1966 B=feburary 2=feburary 2nd. Is this right or does holley have some strange style of code?

Me thinks 6-1966, B-Feb, 2-second of the month. Feb 2nd, 1966. Probably wrong though.

A guy on the ford carbureter forum told my brother that 6B2 was 1966 december 2nd week and I just cant see how he could decode it that way. Anyone else have a clue?

The guy on the carb. forum explained the code like this- year-month-week. the year part is easy the month part is where it gets tricky. Jan.to Oct. is 1 thru 0 and Nov.-Dec. is A and B . A date code of 6B2 would be 1966-Dec.-2nd week. The complete # for this carb. is C3AF-9510-BJ List-2805 he thinks this could be from A 67 GT500 with 427 ,also it's one of two the mate having a BK in place of the BJ. Anyone have A clue what this carb. might be valued at?
