I am in the process of getting an old 1958 f-100 back from the dead and amongst to the wiring disaster that I am dealing with I need a carb. I have a 1960 F-100 that I obtained for free that has terminal cancer and I am using it as a donor truck. It is fixable but I do not feel like doing that much cancer repairs. The 60 came with a 272 (not original) and it had what I believe to be a Ford model 94 2 bbl carburetor with 1 1/16 butterflies which I believe to be the 185 cfm carb. The 58 that I am trying to get going and the carb stolen before I picked it up. I am looking at the Holley 2300 or an autolite 2100 for it but since I have a 3 bolt 2 bbl intake as a spare I was wondering if the old 185 cfm would be too small for a 292. I have a 4 bolt 2 bbl intake which I am thinking about picking up a Holley 2300 for it but I also have a 4 bbl A intake and with an adapter I can put my 4 bbl Holley 450 cfm on it. I am just curious what is the smallest carb a 292 can use? Would the 185 be too small? I am way very thinking this and I am not going for power. I believe the 292 is still stock and I am planning on rebuilding it but not at this time. I want to see how she runs first. It is not the original motor since according to the data plate the truck should have had a 272.
