Autolite 4100
A Ford design that looks similar to a Holley, this carb is a very underrated choice. Coming in sizes useful for a Y, the 4100 uses Holley jets and power valves. The annular discharge booster venturis are very efficient. A great choice for an all-Ford ride, the 4100 is simple and reliable. 3 sizes were made: a 480 cfm unit uses 1.08”venturis, a 600 cfm unit uses 1.12” venturies, and a rare, 1958-only version came with 1.19” venturis for 650 to 670 cfm. Check the carb base for venturi size numbers.
