D. Disconnect the choke rod or heat tubes (if equipped).

F. Unbolt and remove the carburetor from the manifold.

INSTALLATION NOTES:
CHRYSLER APPLICATIONS:
WARNING: This carburetor is not designed for use with any Chrysler automatic overdrive transmission. SEVERE
transmission damage may result from improper application use.
1. If you are replacing an existing Holley® carburetor, you may need to purchase and install a throttle lever extension (Holley®
P/N 20-7) on the carburetor. Remove the throttle stud and nut from the original carburetor. You can purchase a new stud
from your Holley® dealer (Holley® P/N 20-67). Install the stud in the throttle extension lever (Figure 1).

FORD APPLICATIONS:
NOTE: Unless replacing an existing Holley® Carburetor, you will need to purchase Holley® P/N 20-91, spring and perch kit, for
Ford automatic transmissions.
1. Install the new throttle ball, lockwasher, and retaining nut to the carburetor throttle lever in the same position as the existing
carburetor.
2. Insert the transmission kickdown screw with the black retaining clip on the transmission kickdown lever (Figure 2). This
assembly must be installed according to the detailed drawing (Figure 3).
