Ford Autolite 4100 4V carburetor, C5AF-F. (C5AZ-9510-K) The sticker on the float cover states this is a Holley Reman. It does not look like it was used, but I got it without a box, or paperwork. I would kit it before use. The Ford parts book lists this for a 1965 352 V8 engine. The carburetor looks complete. There is no warranty or returns on this. I will refund shipping overage if any.
