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.
