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.
Street-smart tuning: Compared to the older AVS model, the AVS2 shines in real-world driving conditions—offering better fuel economy, smoother cold starts, and superior low-RPM cruising.
Adaptable configurations: Available in 500-, 650-, and 800-CFM options, with choices in choke (manual or electric) and finish (satin, black, or chrome).

This avs2 carburetor is a standout for anyone seeking a refined, all-around performance upgrade. If you’re installing an avs carb, you're gaining smoother throttle response, better fuel control, and street-ready flexibility. And if you're upgrading your ride with an avs2 carb, you’ll appreciate the combination of tunability, reliability, and drivability packed into these carbs.

Experience a carburetor engineered not just for power, but for polished performance—every drive.
