These Quick Fuel Q-Series carburetors are ideal for drag racing applications. They feature the Proform high-flow main body, which includes 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. Q-Series carbs have a CNC-machined billet throttle body base plate assembly to provide an exceptional blend of strength and perfection. The base plates feature slabbed throttle shafts, used in conjunction with low-profile button-head screws, to maximize airflow and performance. Other benefits are an adjustable secondary pump cam bracket, except for the Pro Vac series, allowing fine tuning of the secondary system. On Pro Vac models, the vacuum secondary is adjustable and includes a billet cover. Standard fuel bowls include notched floats and jet extensions for drag race specific applications.
