Carb guys, How to decode my 4100?

  • I was digging through my attic today and came across an autolite 4100 I acquired about 10 years ago when building a 61 Thunderbird. As I recall the carb is from a K mustang. The unit has a mechanical choke and still wears the original Ford stamped tag.


    What car did this carburetor come from? A 66 K car?


    Tag reads; C6ZF-C

    A 5HE


    On the side it has the 1.12 indicating venturi size and there is a small number 3 above the 1.12 symbol. The front driver mounting flange has a 6ZC stamped onto it. A number 34 appears on the rear passenger mounting flange. A date of 11-5-63 is cast into the bottom, possibly the date the mold was made?


    This site has been great to check out, the wealth of information is amazing!


    Thanks for the help.

  • Pat,

    You have a 1966 Mustang 4100 HP carb made in the last week of August, 1965, that's the '5HE' date code. The 'A' before the '5HE' is the revision. That carb was also used on 1967 HP cars with an appropiate date code. The rest of the cast in numbers are size - 1.12, original cast date - 11-5-63 and the mold number - 34. The '6ZE' is the short version of the tag part number, C6ZF-C. Naturally, there are more associated part numbers, the full one - C6ZF-9510-C, the service part number - C4OZ-9510-F, the replacement number - C4OZ-9510-G and probably some others less known.
