Edelbrock AVS2 Series™ Carburetors


650 CFM, MANUAL OR ELECTRIC CHOKE
(THE ULTIMATE PERFORMANCE CARBURETOR)
The AVS2 Series is the next generation in Edelbrock carburetors. The AVS2 features annular flow primary boosters with a new calibration for improved off idle and cruising performance. The annular flow booster design delivers improved fuel atomization to eliminate flat spots that may be encountered when the carburetor transitions from idle to full throttle. Each annular booster features eight, equally spaced orifices to improve fuel metering from idle to the main. The improved flow metering makes this carburetor ideal for use with a wide variety of small-block and big-block engines with either dual- or single-plane intake manifolds. The AVS2 includes both timed and full vacuum ports for ignition advance. It comes with: Metering Jets - Primary .101, Secondary .098; Metering Rods - .070 x .037; Step-Up Spring - orange (5" Hg). Use carb Studs #8008 or #8024 if needed. Match with an Edelbrock intake manifold for the ultimate induction upgrade.

WHY IS AN ANNUAL BOOSTER BETTER?
AVS2 Series 600 cfm Electric Choke Carburetors by Edelbrock
The typical downleg boosters (on the left), are located in the carburetor primaries and simply provide fuel down the center of the venturi. Annular boosters (on the right), feature eight equally spaced smaller holes for better fuel atomization. The improved fuel atomization eliminates flat spots when the carburetor transitions from idle to part throttle for better low rpm performance. The annular boosters can also potentially offer improved mileage in some applications.

WHAT OUR CUSTOMERS THINK!
"Last weekend, I took a cruise from Arlington to Spokane. This was about a 350 mile trip one way, plus I drove through the Snoqualmie Pass at an elevation of 3,000 feet. On last year's trip I got around 16 mpg, this year it was closer to 18 mpg. Throttle response off idle is phenomenal! When compared to the Holley, it's not even in the same league - the AVS2 out performs it easily. Aggressively opening the throttle gave a very crisp response and excellent power."

- Brian Hosenfeld, 1966 Chevy Nova

"The smooth throttle response is the largest comparable change in this new carb. It just seems like the restriction has been removed on my car."

- Mark Taylor, 1968 Chevy Chevelle

"Super responsive, made traffic cruising much more enjoyable."

- Michael Volkmann, 1971 Plymouth Duster
