3.4.1.3 Assemble and Install the Ratio Arm
Find the Ratio Arm from your COMPUSHIFT II Kit. It's the small oval piece of metal (shown here) with a
protruding stud on its smaller end.
For Edelbrock AFB or Holley carburetors, remove the inset washer. For Rochester Quadrajet, leave
the washer in place.
Install the Ratio Arm onto the carburetor linkage as shown, using the ¼-20" x 5/8" pan head Phillips screw,
washer, and nylon insert lock nut.
The Ratio Arm is designed to mount in the linkage where a kick-down cable normally attaches.
The washer sits between the carburetor linkage and the nylon insert lock nut.
Gently snug the screw and nut, but do
not
completely tighten.
3.4.1.4 Align the Ratio Arm
Edelbrock AFB & Holley
Set the Ratio Arm so that the center of its pin is aligned with the edge of the carburetor linkage, as shown.
Tighten the screw and nut in this position.
Rochester Quadrajet
Set the Ratio Arm so that its pin is vertical.
Tighten the screw and nut in this position.
