The Edelbrock Thunder Series AVS2 800 CFM carburetor (#1912) uses Annular Flow Booster technology for improved fuel atomization and near-EFI drivability on high-horsepower small- and big-block engines. It delivers refined throttle response, reduced flat spots and easy part-throttle tuning via changeable metering rods and springs. The two-piece design allows float and component access without draining fuel; available in manual choke with EnduraShine or satin finish, assembled and calibrated in the USA.
