I’m trying to identify an early Carter AFB. only stamped numbers I can find are 37208 B And another stamped number is: 0-1552. I tried a cross reference chart but couldn’t find and exact match. 37208 plus an addition 3 numbers come back to a 1968 Chevrolet with a 327 pg. would like to know the cam and the proper number so I can revuild it. Thanks for any help or info. Jerry
If it comes back as a Chevrolet, it's probably a Rochester, not a Carter AFB. Pictures would help. I will let the experts comment on your carburetor.
maybe a dumb question but the carb has “Carter AFB “ sand cast in the body. Would it still be a Rochester........are they the same as Carter. I agree, I think it’s an early 60s carb for a 327 but how would I order a rebuild kit. I have an A rpu with a 57 283 and a dual range hydro. It has a Rochester on it now. Just thought I’d try the Carter just for grins.
Application 1964 - 327/300HP Standard Transmission Specs CARB: Carter AFB Carburetor #3721s DATE CODE: ? AIR CLEANER: 4.5" GM #: 3851761 AIR HORN #: 6-1518 CASTING #: 0-1552 CFM 500
The number is probably 3720SB. Carter AFB for 1965 327 A/T. Rochester 4 jet is a whole different animal.
As Bchctybob stated, 3720SB From my website: Carter numbering systems. Three different types of numbering systems are found on Carter produced carburetors. (1) On carburetors built for Chrysler Corporation, a series of 3, 4, or 5 letters and numbers; i.e. EV1 or D6H2. (2) On carburetors built for Ford Motor Company, the “Ford” numbering system which is “lnll – l(l)(l)” or letter, number, letter, letter dash letter (possible letter) (possible letter) i.e C5VF-A. This system is codified in that the first letter is the decade (B=1950’s, C=1960’s, etc.); the number is the last digit in the year; the 3rd and 4th letters (before the dash) represent the vehicle model (VF=Lincoln); and the letter or letters after the dash are a modifier which distinguishes the exact application. Thus in the example C5VF-A, the carburetor would have been the first application for Lincoln in the year 1965. (3) The traditional Carter numbering system which consisted of 1, 2, 3, or 4 digits; followed by the letter “S”, possibly followed by another letter. It is extremely doubtful that any of the single, double, or early triple digit tags will appear; as they were produced before 1930 and were constructed of red cardboard. The metal tag appeared about 1930 with tag numbers of about 300s. The 4 digit tag appeared in 1952, and was continued on until the end. The letter S and following letters, when present, have caused much speculation (mostly incorrect). In Carter’s terminology, an individual part such as an idle mixture screw was a single part; whereas two or more individual parts sold together such as a needle, seat, and gasket were sold as an “assembly”. Carter used the suffix letter S to denote assembly. Since all carburetors are composed of multiple parts, the letter S was appended to all carburetors using the traditional numbering system i.e. 938s. If a significant engineering change was made to the carburetor, the letter “A” would be appended to the S (i.e. 938sa). A second change would have the letter A replaced by the letter B (i.,e. 938sb). The highest engineering change of which I am aware is 4 i.e.938sd. Contrary to popular belief, the S DID NOT mean standard transmission, nor the SA automatic transmission. Hope this helps. Jon.
Air horn # matches 6-1518. Casting number matches 0-1552. 37208 B with a B7 below still no match but I think it’s narrowed down to the following posts. Sincerely appreciate all, the information provided Jerry
