The Edelbrock AVS2 Series #1906 650 CFM Thunder carburetor is a satin-finished four-barrel unit with electric choke for street use on small-block and some big-block engines. It uses annular flow primary boosters with eight evenly spaced orifices to improve fuel atomization and reduce flat spots during throttle transitions. The #1906 includes timed and full vacuum ports and arrives with metering jets, metering rods and step-up spring for common Edelbrock manifolds.
