Willys Carbs 44120A Details

Willy's two-barrel carbs make much more power than stock, and now feature aluminum construction for major weight-saving benefits.

This all-new Willy's 500 CFM 2-barrel 4412 carburetor is an all-new replacement for discontinued P#800-44120. It has a 1-3/8" venturi and a 1-11/16" throttle plate. It uses an all-aluminum body, metering block, and fuel bowl - meaning it sits on the scale at half the weight of the previous version. Internally everything is the same, so these 2 barrel carbs will pass tech gauges and produce great torque and horsepower. They are popular on NASCAR late models and are IMCA approved. This two-barrel carburetor has "4412" stamped on it, and has a natural aluminum finish.
