Product Description

The Edelbrock 1906 AVS2 is a 650 CFM 4-barrel carburetor designed for gasoline V8 engines with square-bore intake manifolds. Its electric choke allows reliable cold starts and smooth drivability, while annular-flow primary boosters enhance fuel atomization and throttle response. Mechanical secondary operation ensures simplicity and reliability, and the all-aluminum body provides durability and resistance to corrosion.

Factory jets and rods offer ready-to-run street performance, while the vacuum ports allow integration with vacuum-advance distributors or other vacuum-driven systems. As a universal-fit carburetor, proper installation depends on verifying intake manifold flange type, fuel system, and ensuring the engine does not rely on EFI or emissions/EGR controls. Adjustments to fuel pressure, float levels, and ignition timing are recommended for optimal performance and longevity.
