Edelbrock ED1905 AVS2 650 CFM Carburettor

The Edelbrock ED1905 is a 650 CFM AVS2 four-barrel carburettor with a manual choke, mechanical secondaries and Holley 4150 square-bore mounting pattern.

The AVS2 uses annular-flow primary boosters to improve fuel atomisation, throttle response and fuel delivery during the transition from idle into the main circuit. This helps reduce the flat spots commonly experienced with conventional booster designs.

Its adjustable air-valve secondary controls how quickly the secondary airflow comes in, giving the engine the airflow it needs without making the carburettor feel lazy or doughy at lower RPM.

Total Performance rates the Edelbrock ED1905 as one of the best 650 CFM carburettors for a street-driven Small Block Chevy 350. It is also an excellent choice for Ford 302 Windsor, 351 Windsor, 351 Cleveland, Holden V8 and other mild small-block and big-block combinations.

The carburettor comes with a single fuel inlet. It can also accept the Edelbrock #8132 dual-feed fuel line, sold separately.

The ED1905 includes timed and full-manifold vacuum ports for distributor advance. It suits dual-plane and single-plane intake manifolds with a Holley 4150 square-bore mounting pattern.
