Autolite 2100
Equipped from 1957 to 1969 on a wide variety of engines, from the 221 Windsor to the 390 FE Big Block. The 2100’s are popular more for their low maintenance than performance, though in reality they have great potential for pulling the most Horsepower out of an engine while maintaining excellent fuel mileage, especially for a 40+ year old carburetor. The 2100’s, like the 4100’s, use annular discharge boosters that atomize the fuel. This results in performance and fuel efficiency more akin to a throttle body injection system than a carburetor. Atomizing the fuel allows it to burn more evenly, creating more power with less fuel, and therefore, more efficiency.
