Holley 2300 series 2-bbl carb. I had it on a 302 then a 289 in my '69 Bronco and it made them both run like an old Singer. Eventually swapped the V8 for an L6 and have had this on the shelf every since. Always stored inside. It's set up for a manual choke. I have the dash pot for it. I don't think it has even a years use on it and everything on it seems to move smoothly still. Time for it to move on. Price reduced.
