66 Holley 3367 decode help

[George D. 31849]

Can anyone help me decode the date on a Holley 3367 I have. The date code is 0037. It also has these numbers: 3884505 and metering block number 4743. Thanks

The #3367 carb is a non-original, service replacement if that is what you're wondering.

3367 1966 327 corvette 300HP,3884505 is the GM part number and the 4743 is the correct metering body,0037 is strange but my guess is the 3rd day of 1967,77,87 etc.

An original carb and some replacements would have a DA after the GM part number. If it has slotted fuel bowl screws its probably a 1977 carb. If they are hex its probably 1987, although these items can be changed. With slotted choke plate and throttle plate screws, it's probably an earlier replacement, with phillips the later. 4743 is the correct metering block. Later replacements used a different number.
