1.14 venturi base plate stamp: CCAE-AC The float and fuel inlet are different than on a C5ZF-B that I have C5 is on the right
The carb on the left is a pipe thread fitting and the one on the right is a flare fitting. The pipe thread carb probability had the screw in filter at the carb. As for the float they with work in either carb. The narrow float was suppose to leave more fuel in the carb. One of Ford crazy ideas. I see no choke pull off diaphragm inside the air horn. so they should both be per 1970 carbs. If you look that the accelerator pump you see that the one on the left has a deeper housing. They both that the same diaphragm but the one oon the left also has a rod (small plug) that goes between the diaphragm and the lever. The 1.14 venturi make them 300 CFM carbs.
