holley carb ID help

[Joe T.]

I have an early 66 327/300hp no A/C, I'm trying to date my carb and verify it is correct, on the air horn top number is 3884505-DA, next row down list 3367, last row 0304, I can't figure out that date, the number on the metering body is 4743, I believe that the 3367 on the air horn and the 4743 on the metering body are correct, car build date is oct 6, 65. Any help is appreciated.

The carb model is correct but the date code 0304 is for a service replacement. The original would have a 3 letter code like 591, 1965, September, 1st week.

'Corvette by the Numbers' byAlan Colvin is a good source for Corvette dating codes.

Joe -

That date is January 30, 1974 (or '84 or '94).
