Re: Carburetor Date Code

What is the build date of your engine ? I would look for 30-90 days from build date of the engine. You can go back as much a 6 months but that's not typical.

Yes of course engine build date. Thanks for that info Micheal.

Engine build date A19 6
Carb date code 5B 4

Would that be to soon, or acceptable for judging?

Typically, 3 digit Holley codes are Year / Month / Week (Link Below)

Are you sure your "B" is not an "8"?

or 1965 / August / 4th week

What is the "List" number on your carburetor? (Holley Part Number)

3882835 (or 3892341 for cars with air injection reactor)

Paul,

That A 19 6 must be a casting date of the block which is Jan 19th 1966. What is the date on the engine stamp pad ? So you want a carb dated in Nov. or Dec. of 1965 would be ideal.
The 5 B 4 is really close Dec 4th week, but it should work OK. I would like to see 5 B 1 or 5 B 2.

Just my .02

Re: Carburetor Date Code

Engine build date has nothing to do with the carb date...........as engines were all built and test fired without the carb in place. Butane or similar was used for test firing. Carb was first installed at St Louis.

Ideally I would like the carb dated about 2-6 weeks prior to the CAR build date, based upon the car's VIN. NCRS allows six months prior to car build date, but that is excessive.

Looks like you are good to go re part number and date.

The date code "5B4" translates to 1965, December, 4th week of December. This is a perfect match for a car built in mid February 1966. You are "golden".
