AVS2 650 CFM Four-Barrel Carburetor

Manual Choke with Satin Aluminum Finish

Annular Flow Boosters for Better Fuel Atomization

1.44 in. Primary and 1.75 in. Secondary Bores

Adjustable Float Level

Non-EGR Design

650 CFM is the size most street small-blocks actually want, where an 800 would be too much carburetor for the displacement and airflow on tap. The AVS2 uses annular flow boosters to atomize fuel more finely at low airflow, which is exactly the condition a smaller engine spends its life in, and the float level can be set without draining the bowls.

Manual choke, satin aluminum finish.
1.44 in. primary bores and 1.75 in. secondary bores, 3.25 in. body height.

AVS2 Series, The Next Generation Of Edelbrock Carburetors

Edelbrock AVS2 carburetors feature annular flow primary boosters with enhanced calibration for improved off-idle and cruising performance. This design features eight equally spaced holes to improve fuel metering and atomization to eliminate any flat spots when transitioning from idle to throttle. Ideal for use with a wide variety of small-block and big-block engines with either dual-plane or single-plane intake manifolds. The AVS2 includes both timed and full vacuum ports for ignition advance.

The elbrock AVS2 carburetors represent a refined evolution in fuel-delivery technology, engineered to eliminate flat spots and deliver smooth, efficient throttle response. These carbs feature annular-flow primary boosters—a design that utilizes eight uniformly spaced orifices to enhance fuel atomization and metering, resulting in seamless performance from idle through acceleration.

Whether you're running a small-block or a big-block engine—paired with a dual-plane or single-plane intake—the AVS2 is calibrated for versatility and precision. It includes both timed and full vacuum ports to accommodate modern ignition systems.

Why Choose AVS2?

Improved drivability: Annular boosters smooth out throttle transitions and offer crisp off-idle control.
