GM APPLICATIONS:
WARNING: If you are using this carburetor with a GM overdrive transmission TH700R4 or a TH200R4, you must use a
transmission kickdown cable bracket (Holley® P/N 20-95) and stud and kickdown throttle bracket (Holley®
P/N 20-121). Otherwise, SEVERE transmission damage WILL result. This carburetor is not designed to
work with ANY other automatic overdrive transmissions.
1. Remove the throttle cable ball and automatic transmission kickdown stud (if any) from the original carburetor, and mount
these in similar locations on the Holley® throttle lever. If the original throttle cable is too large, a new throttle ball or stud is
needed (Holley® P/N 20-2, 20-38, or 20-40).
INSTALLATION:
1. Install the carburetor-mounting studs in the proper location on the intake manifold carburetor flange.
2. Place the new carburetor flange gasket, provided with the carburetor, in the proper position on the intake manifold.
3. Place the carburetor on top of the flange gasket on the manifold. Install the hold down nuts and snug down progressively in
a “crisscross” pattern (60-80 in./lbs.), as shown in Figure 5.

WARNING: Overtightening may result in warped or cracked carburetor throttle body.
4. Before connecting the linkage, operate the throttle lever to ensure the correct travel (no sticking or binding), by opening to
wide-open throttle and back to closed throttle several times. Correct any sticking or binding conditions before proceeding.
5. Reconnect the throttle and transmission kickdown linkage and throttle return spring (Holley® P/N 20-89). Operate the
carburetor throttle lever by hand to ensure the correct travel (no sticking or binding) by opening to wide-open throttle and
back to closed throttle several times. Correct any sticking or binding conditions before proceeding.
