which version of carb is correct

    • Official Post

    If your Kar has a PCV valve it will be the C5OF-J. If it has a road draft tube it will be a C5OF-L.

  • Hi Fred, thanks for the info.


    Right now I have an original 6CZF-C Autolite 4100 with 6CZF-C, but it appears I have the wrong one as I thought. That's why posted interest in the C5OF-J.

  • There have been C5OF tagged carbs that were stamped on the base with C4OF-AL. Nothing was wasted at Ford, so some C4OF carbs went into 1965 cars. Other than the tag date code preceeding the engine assembly date, almost anything could happen. Hard to argue with a C5OF carb, but C4OF could be correct as well.
