The Quick Fuel Technology Q-850-BAN is a 4-barrel carburetor engineered for the demands of drag racing and performance applications. Purpose-built for the dragstrip, this carburetor is ideally suited for bracket racers and weekend warriors. It features a lightweight aluminum main body with recessed air bleed cavities and die-cast venturi machined to exacting tolerances for outstanding throttle response. Key components include billet metering blocks for a uniform fuel curve and a billet aluminum throttle body for enhanced durability and precision. The Q-850-BAN is equipped with notched floats and secondary jet extensions to combat the forces experienced during hard launches. It also features aluminum fuel bowls with dual sight glass windows for easy fuel level monitoring and PTFE coated and sealed shafts for smooth operation. With mechanical secondaries and a dual inlet, this carburetor offers robust performance tuning capabilities. This carburetor has a square bore flange bolt pattern and can replace Holley, Edelbrock, Carter AFB, and Autolite style carburetors with a 5 3/16" x 5 5/8" bolt pattern. An adapter is required for installation on spreadbore intake manifolds. The Q-850-BAN is compatible with gasoline and is designed for forced induction and supercharged blow-thru systems. It is legal for sale and use on uncontrolled (non-emissions controlled) vehicles, including 1965 and older U.S. manufactured California certified vehicles, 1967 and older U.S. manufactured federally certified vehicles, and 1967 and older foreign manufactured vehicles.
