1957 FORD THUNDERBIRD CODE

About the only pieces interchangeable on the Autolite from 1957 to 1958 are the body screws. Also, the Autolite was totally redesigned for 1958. The Autolite also has a secondary diaphragm. The Carter's major issue (I posted this earlier) is the unreliable secondary diaphragm. Others will have differing opinions, but mine is that both the Carters and the Autolites for 1957 have issues although fewer than the 1957 Holley. If you are not hung up on originality (your query asking for modern replacement), then (as noted by others) both Carter and Autolite were used by Ford in 1957 on the passenger cars (other than T-Bird). As noted above, the original carb for your T-Bird would have been a Holley list number 1272 for a standard trans, or a Holley list number 1273 for an automatic trans.

While Carter had a racing only spread-bore in 1969, Carter did not release spread-bores for production until 1971.įord did use the thermoquad on many of their high performance non-smog engines in the mid 1970's and newer. The secondary diaphragms were trouble, period, and Carter refused to continue making them.įord (Lincoln) used Carter though most of the 1960's until the spread-bore carburetor became popular. 1956 was a Great Year!Īctually, it was more like Carter gave up on the design which Ford wanted to use.the unreliable secondary diaphragm!Ĭarter made them for Ford (and a few Chrysler) for a couple of years, instead of the bulletproof airvalve design used for others. I've hadĪt least four '56 Fords, the last of which was a Parklane wagon with O/D. I think Ford gave up on the Carter's after '57. was also used on the '57 Continental MK II. I had an all original, low mileage '57 Ford Skyliner that came with a Carter 4 barrel. Since Jon has a '57 T-Bird, I was trying to focus on what carburetors were available for his particular car, and, yes, in 1957 Ford offered quite an array of carburetors for the Y Block passenger You are correct the Autolite wasn't available on T-Birds in '57 but they were available on 312's with A/T in '57. However, it will adapt to most '57 and later Ford style intake manifolds. The Autolite 4100, which was a FORD designed carburetor, was never used on a '57 T-Bird, but first appeared on Fords in 1958 or 1959.

Shrunken secondary gaskets can also leak fuel into the secondary throat and into the manifold. It's ruptured rubber diaphragm is letting the front fuel bowl empty into the intake manifold, causing the flooding. If its dripping fuel into the front two barrels, your power valve that's located in the primary (front) fuel metering block is shot.

Summit Racing carries them at a reasonable price. linkage and CFM wise would be a Holley 0-1848-1. This 4548 you have is a generic FORD replacement model that adapts to many later Fords and your T-Bird. The 4150 did not have adjustable floats, but it did have a secondary fuel metering block. Your carb is a 4160 that has adjustable float levels and has no secondary fuel metering block. The List #, also on the air horn was 'LIST 1273-1 1A or similar.
