What do all the numbers mean on this tag?

It seems as though each year-car has different part numbers - this one, from 1969 R/T AC car:

I can tell you that its an early '69 4640 Carter carb.   The "S" is the first series....."SA"would be the next revision to the carb  (I think it was the addition of the 2 idle mixture screws as opposed to the single one on the "S" model)

The 4640SA carb is correct for a '69 440 with A/C and auto trans (which is what I am running...see pics of mine)

the "2928" on the tag could be the Julian date code.....possibly the 292nd week of 1968?

Great pics! Great info!  Any ideas on the large # 92 on the tag?  What about the letters ahead of 4640S or on yours, 4640SA?

  The carb I pictured is original, from an early 1969 Charger R/T

While we're on the subject, I have a '69 440 automatic car with a 4618S carb, which I'm assuming is the original carb (?)  In the picture below, note the single mixture screw in the center of the carb just above the pvc hose, which is threaded left hand. Can anyone tell me what the deal is with that? You'll also notice that a previous owner had removed the lead covers to gain access to the traditional mixture screws. Thanks in advance.

It is the assembly date code and I'm pretty sure you meant DAY not week. 292 = Oct 18th.
Large 92 = last two digits of carb part number. Also , these are the numbers you find on the BS.
K8 = date code of October 1968.

The carb I pictured is original, from an early 1969 Charger R/T

The dating on the carb would make it for an engine assembled, probably, in late OCT and probably in a car with a late OCT or early NOV scheduled production date.

Yes, the 4618 is the correct carb for a 69 440 HP with automatic and no A/C. Here's the tag off my car.

The screw is the idle mixture screw.

Whoops yes I did mean day Doug!   As usual, a spot on explanation from you!

What does the 81 mean again? If it a part #, I must have a misprint in my book 


On the pic I posted, 92 is the last two digits in Chrysler part # 2946592 which does correspond to Model # 4640S

The other carb pictured, 4618S has that same part # (2946592) so maybe the book got it wrong?? Wouldn't be the first time

I don't know what the original part number is. If you are looking at a 69 parts book in section 14-30-1 with January 1971 update, notice the heading states Service number. The original factory installed part number may or may not be listed. Many parts were superceeded after they came off the line. The 81 carb was superceeded by the 92 carb meaning if an 81 carb needed to be replaced several years later, a 92 could be used in place of the original. If you look in the right hand column, you'll see similar original carbs ( look at the 340 carb and a 383 carb) superceeded by a different part number.

the "2928" on the tag could be the Julian date code.....possibly the 292nd week of 1968?

The "SA" suffix usually represents a "replacement carb" & the "F0" stamped on the foot would confirm this carb to being built June of '70.

So the K8 stamping on the pic I posted, means November 1968, correct?

The "SA" suffix usually represents a "replacement carb" & the "F0" stamped on the foot would confirm this carb to being built June of '70.

In this instance, the carb can be identified as a replacement part only by it's date code.  A part made in June '70 could not have been OE on a '69 model car, and the SA designation simply refers to the fact it is the later version of the carb itself (e.g. two mixture screws, etc. as Chris mentioned).  At least for 440 Carter 4bbl carburetors, the changeover from S to SA happened right around January or February of '69, so all late L-engined 1969 model cars will have an SA carb with two mixture screws straight from the factory... as would any replacement parts made after the revision changeover, such as the carb in Chris' picture.

Incidentally, the assembly-line part number for the 4618S (and SA too, for that matter) was 2946581, with the last two digits showing up on the Broadcast Sheet as already mentioned.  All 1969 carburetor assembly line part numbers from 1bbl's through 4bbl's had the same "prefix" of 29465 - plus the broadcast sheet designator.  Hemi carbs didn't technically have a broadcast sheet part number though, so I suppose that's the exception which proves the rule.

Here is the build sheet to match the carb above - note: 24 is in the box marked CARB. I cannot find any carb with the ending of 24    

My guess, is someone fat fingered when typing and maybe the 92 is there, just misaligned - the 9 from ENGINE and 2 from CARB would be the 92 needed

As stated above...October of 68

[XS29L9Bxxxxxx]

MYSTERY SOLVED!!!

Check out the "double stamp" on the one character in the VAC FIT block  

...that messed up the alignment for the rest of that line of codes

If F = June (for the sixth letter, wouldn't K = November for the eleventh month?

Yep, you nailed it.  The track printers occasionally did get off a bit, and yours is a classic example.

They skipped "I" because of its similarity to the number "1".  K=10th month if you skip "I"...  Strange but true.

Cool link. Thanks!

...looks like the whole line below that (as a result of double-typing another box on that line) is misaligned...
