Description

Get big-time performance with Quick Fuel Q-Series 4-barrel carburetors with high-flow main bodies, which include either down-leg or annular boosters, screw-in idle and high-speed air bleeds, accelerator pump discharge nozzles, and a blended venturi area. These carburetors have CNC-machined billet metering blocks with 4-stage emulsion to provide more precise fuel metering, improve throttle response, and give a more uniform fuel performance curve. With so many great benefits and their blend of performance and drivability, it's no wonder that these Quick Fuel Q-Series carburetors are the popular choice. So, go ahead--throttle it up with Quick Fuel!
