How do I adjust the linkage for synchronized operation?

All adjustments should be made with the carburetors at the wide-open throttle position. This ensures that all carburetors are synchronized and opening at the same rate. It's recommended to check that the arms do not become inverted after any adjustment.

What is the difference between progressive and non-progressive linkage?

Non-progressive linkage means all carburetors open at the same time and at the same rate relative to pedal position. Progressive linkage typically has one carburetor opening first, followed by another at a different throttle position.

What components are included in the kit?

The kit includes the linkage itself, a return spring and bracket, a throttle linkage control arm, and a ball end stud. These parts are used to connect the linkage to your vehicle's throttle rod or cable.

About this part

Product Details

Edelbrock is well-known for performance parts, especially their carburetors and manifolds. This X1 Linkage Kit, part number 1031, is designed to work with their X1 manifold and six two-barrel carburetors on a small block Chevy engine. It ensures all six carburetors operate together, opening at the same time and maintaining the same throttle angle. This synchronous operation is key for getting consistent performance from a multi-carb setup.

This is a non-progressive linkage, meaning there's no delay between the opening of different carburetors; they all move as one. The kit includes a throttle linkage control arm and ball end stud, which connect to your vehicle's throttle rod or cable. You'll need to plan where this connection point will be on the linkage operating shaft. It's recommended to install this linkage with the manifold off the vehicle, on a level surface, to make adjustments easier. Pay attention to any valve cover features like breathers or PCV valves that might interfere with the linkage's movement. All adjustments should be made with the carburetors at wide-open throttle to ensure they are synchronized properly. Some trial and error might be needed to get everything perfectly balanced, and it's important to check that the arms don't become inverted after adjustments.

Proper installation is up to the installer, and incorrect setup can lead to poor performance or engine damage. This kit is a bolt-on component, but careful setup is required for optimal results.
