Quadrajet carburetors were also built under contract by Carter. This was due to the fact that Rochester could not keep up with the demand for carburetors at various points in their production. [citation needed] Carter-built Quadrajets will have the name "Carter" cast into them, but are functionally identical to the Rochester-built equivalent.
The Cobra Jet (429CJ) was fitted with a Rochester Quadrajet 715 cu ft/min (20.2 m 3 /min) Spreadbore 4-bbl carburetor, a larger camshaft; a special set of cylinder heads (DOOE-R) 73.5 CC, combustion chamber and canted valve configuration, with pushrod guide plates (DIOE-6465-AA) Intakes valves were 2.24 and exhaust valves were 1.74, with non ...
In 1953 an advertisement in Life stated: "Rochester builds original equipment carburetors for Chevrolet starting with 1950, Oldsmobile from 1949 and Cadillac from 1951.

They were identical to Rochester's units, except the Carter name was stamped into the body. In Carter's final years in the early 1980s, they also produced Weber carburetors under license, such as the three-barrel Type 40IDA sold as replacements (or fuel injection retrofits) for 1960s and 1970s Porsche 911 S.
This was accomplished by merely disconnecting a single wire from the transmission's "3rd-gear switch", or running it through a switch inside the car for manual override. The 368 was dropped from most Cadillac passenger cars after the 1981 model year, although the V8-6-4 remained the standard engine for Fleetwood Limousines and the carbureted ...
