Edelbrock's AVS2 500 CFM Carburetor #1903, featuring Annular Flow Booster technology, revolutionizes dual-quad applications with superior fuel atomization. Specially calibrated for engines running two four-barrels, this carburetor delivers EFI-like drivability with a noticeable response the moment you press the gas pedal.
The Annular Flow Boosters ensure refined fuel distribution through eight equally spaced orifices in the booster rings, replacing traditional down-leg boosters. This innovation eliminates flat spots, significantly improves throttle response in the low- to mid-RPM range, and preserves Edelbrock's renowned top-end power. The AVS2 is resilient to engine backfires, thanks to the absence of power valves susceptible to blowouts.
Tuning the carburetor is made swift and straightforward—metering rods and springs can be changed in seconds without carburetor removal or fuel draining. AVS2 carbs maintain a consistent tune, offering stability in performance. Updated primary and secondary booster clusters provide precise calibration for modern fuels and octane levels. The Qwik-Tune Secondary Air Valve allows easy calibration adjustments, adapting to your specific application with simple hand tools.
The two-piece ease-of-tuning design facilitates float level adjustments or internal component replacement without fuel draining or carburetor removal. The AVS2 500 CFM carburetor is available with electric choke (#1903) or manual choke (#1904) in satin or EnduraShine finish. For small-cubic-inch single carburetor engines, opt for the specially calibrated AVS2 500 CFM #1901 (electric choke) or #1902 (manual choke). As with all Edelbrock carburetors, the AVS2 Series is meticulously designed, manufactured, assembled, and calibrated in the USA.
