The only carburetors ever available from the factory on M-block (351M/400) engines were the Autolite 2100 and Autolite/Motorcraft 2150 2V carburetors.

The Motorcraft 2150 2V carburetor was used from 1973 to 1979 on M-blocks in cars, and from 1977 to 1982 on M-blocks in light-duty trucks. The Motorcraft 2150 is an evolution of the original Autolite 2100 2V carburetor that was introduced in 1957.
