Generic 1406 Carburetor for Edelbrock Performer 600 CFM 4‑Barrel — Electric Choke, Two‑Step Metering

Generic 1406 is a 600 CFM, 4-barrel Edelbrock Performer-series replacement carburetor with electric choke designed for non-computer-controlled V8 engines.

This carburetor replaces Edelbrock part numbers 1406 and 1406-600, offering a direct-fit option for older performance cars and trucks that do not use computer feedback systems. It’s built with two-step metering rods to help control fuel delivery under changing throttle conditions and reduce backfire risk. Note: Units are shipped randomly from two available carburetor variants; you may receive either one. If you need a specific sub-variant, please contact the seller before purchasing.

Which vehicles will this 1406 carburetor fit?

The Generic 1406 is intended for classic and performance applications that originally used Edelbrock Performer 600 CFM 4-barrel carburetors. It commonly fits older Chevrolet and Ford V8s when used with compatible intake manifolds and linkage. It is not suitable for vehicles that require computer-controlled fuel systems or feedback emissions components.

• Direct replacement for Edelbrock 1406/1406-600 part numbers
• Popular on Corvette, Silverado, Mustang, and GMC pickup platforms with compatible manifolds
• Designed for non-feedback, carbureted engines only

How does the electric choke and two-step metering help performance?

The electric choke simplifies cold starts by adjusting the choke plate automatically as the engine warms, reducing the need for manual choke management. Two-step metering rods alter fuel flow between part-throttle and full-throttle, helping smoother acceleration and reducing the chance of backfire or blown power valves during aggressive throttle changes.

• Electric choke for consistent cold-start behavior
• Two-step metering rods for staged fuel delivery
• Improves throttle transition and anti-backfire control

What should I check before installation?

Confirm your vehicle uses a non-computerized carburetor setup and that the intake manifold bolt pattern and throttle linkage match the 1406. Verify fuel line, vacuum port locations, and throttle/parking choke linkages to avoid fitment issues. If your vehicle has an emissions feedback system or electronic controls, this carburetor is not appropriate.

• Match intake manifold bolt pattern and throttle linkage geometry
• Ensure no electronic feedback/emissions systems are required
• Check fuel inlet, vacuum ports, and accelerator pump compatibility

What performance tuning or maintenance does this carburetor need?

Basic tuning includes adjusting idle mixture screws, float level, and accelerator pump shot for your engine’s displacement and compression. Periodic inspection of the choke heater, gaskets, and linkage will keep performance consistent. If you plan to re-jet or change metering rods, do so incrementally and log changes for repeatable results.

• Adjust idle mixture and float level after installation
• Inspect choke, gaskets, and accelerator pump regularly
• Re-jet or swap metering rods only when necessary for tuning

Who is this for: The Generic 1406 600 CFM Edelbrock Performer-style carburetor suits classic-car owners, hobbyist builders, and performance mechanics restoring or upgrading older V8s that run without electronic fuel control. It’s ideal for street rods, muscle cars, and pickup trucks requiring a direct replacement for Edelbrock 1406/1406-600 carburetors. If your vehicle relies on computer-controlled fuel or emissions feedback, choose a compatible electronic fuel system instead.
