Edelbrock 1905 is the AVS2 650 CFM four-barrel carburetor with a manual choke, satin finish and square-flange mounting pattern. It is the non-EGR configuration.
This part number has a manual choke; electric-choke AVS2 versions use different part numbers. Confirm the intake flange, throttle and transmission linkage, choke controls, fuel-system requirements and hood clearance for the engine build.
The source calibration lists .101-inch primary jets, .098-inch secondary jets, .070 x .037-inch metering rods and the orange 5-inch-Hg step-up spring. Final calibration depends on the installed engine and operating conditions.
