Hello, all. I've bought a 1970 F100 with a 302 and am trying to find out what carb I have on it, as it needs rebuilt. A small sticker on it said reman holley, but the numbers on it were smudged out. I cleaned up the outside with some gasoline since holley should have it stamped on, but to no avail. I was hoping someone on here would have an idea.
Thank you in advance.
It is a typical Ford/Autolite/Motorcraft 2100 2 barrel carb. For a stock size with a 302, the airhorn should have a number stamped on it of 1.08. This is the venturi size. You can google for the cubic-feet-per-minute rating. That was the size of my 72 F-100 302.
Thanks a million. I knew something was off. Just started working on this one. It's my daily, since the '86 is tore apart at the moment. Straight six is all I've ever messed with before now. Again thanks for the help.

Holleys have a stamp on the air horn.
On an Autolite 2100/4100, look on the driver side of the main body and there is a cast "clock face" with numbers in the middle. The numbers can be 1.08, 1.12, 1.18, 1.21, 1.23, etc.
Per Rich above, it is likely a 1.08 but who knows after 40+ years what carb CFM is actually installed.
Look up the numbers on the web for a CFM equivalent.
