Autolite 4100 Tag Decode

  • Hello,


    I have a complete Autolite 4100 carburetor that is said to be off of a k-code Mustang. Can I determine this to be correct given the following tag number?


    Ford

    C GF AT

    B 4FD


    Cheers!

  • Okay, more information. First after some cleaning of the tag I can read the top of a "4" between the "c" and "G".

    Stamped on flange is c4GFAE.

    Venturi size of 1.08 is cast into side with a 13 or 18 cast about 3/8" above that.

  • Seems to me the G should be an O, as in C4OF...


    4100 carbs with 1.08" venturi's are correct for standard 4 barrel engines, and HiPo carbs have 1.12" venturi's.

  • Did the automatic equiped cars have 1.12" venturis as well? Thanks for all of the responses so far. I'm not sure if this carb is off of a Mustang, Fairlane, Comet or whatever.

    The C4GF-AE carb is for a regular fuel 289 non Hipo 64 1/2 Mustang and 64 Comet.
