Does anyone know the model number for a Motorcraft 2150 2-barrell off a 1982 Ford F-250 with a 302 motor and an automatic overdrive trans? The tag was removed by a previous owner and I am looking to get a rebuild kit and they need the number. Thanks

 

Unfortunately due to the vast number of calibrations that were used over the years, you might not be able to get the exact tag back. However, a good parts guy should be able to get you close with the engine and vehicle information.

 

There should be a four digit stamp on the base (number - letter - letter - letter).

The "D" and "F" are constant, and just add in your stamp to the following:

D_ _ F - _ _

For example, if your carb has "4THA" stamped on the base your part number is D4TF-HA. I don't know what the last two letters represent, but the first for can be decoded with this:

The first character indicates the decade of design:

A = 1940s (often omitted)
B = 1950s
C = 1960s
D = 1970s
E = 1980s
F = 1990s

The second character indicates the last digit of year of introduction or revision. The number remains the same until the part goes through a major revision. Example: All '87-'95 Mustang (exc. Cobra) cylinder heads have the same Service Part Number prefix (E7TE) aka Casting Number. Decipher the Date Code to indicate when the part was actually made.
