These throttle brackets are designed to work with the popular Performer RPM Manifolds from Edelbrock. One bracket is for RB engines (413, 426W and 440) while the other is for the smaller 383 and 400 engines. These throttle brackets are the correct height to work with the factory 3 piece kickdown linkage.

The throttle bracket and the kickdown linkage should be installed as shown in the picture above. Notice that the hairpin cotter pin goes into the inner hole in the KD pivot, not the outer hole. The vertical rod in the kickdown linkage will need to be adjusted almost to the end of its range in order for it to be tall enough to work, but it will fit.

If you are not using a factory carburetor then you will need to get the proper extension onto the throttle linkage in order to operate the kickdown linkage. Holley and Edelbrock both sell kickdown extensions for their respective carburetors.

We highly recommend a factory style throttle return spring installed in the OEM location. As shown above, we sell a tall version of the factory bracket complete with a dual throttle spring. It is available from the same vendor where you purchased the throttle bracket.

Adjust the kickdown linkage according to the factory service manual instructions. This throttle bracket is just a taller version of the factory one; it does not change the adjustment procedure or the operation of the factory linkage.
