Brand New Holley Quick Fuel Q-Series Carburetor, Red Billet & Shiny Finish, 850 CFM, Drag Racing, Annular Booster, 4150 Model (Part #Q-850-AN).

Q-Series carburetors are purpose-built for the dragstrip. Equipped with notched floats & secondary jet extensions. High-flow aluminum main body is lightweight & features recessed air bleed cavities for improved air flow. Die-cast venturi are machined to exacting tolerances for outstanding throttle response. Billet metering blocks ensure a uniform fuel curve, while throttle-bodies enhance durability. QFT QuickLink system makes adjusting the secondaries easy on models equipped with mechanical secondaries.


NOTE: This carburetor has the square bore flange bolt pattern. It replaces Holley, Edelbrock, Carter AFB & Autolite style carburetors with 5 3/16" x 5 5/8" bolt pattern. If you have a spreadbore style intake manifold, an adapter is needed to install this carburetor, similar to Mr. Gasket #1932.
