Street Avenger Carburetor Installation, Tuning and Adjustment Manual
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 (Holley P/N 20-2, 20-38, or 20-40). Otherwise, SEVERE transmission damage WILL result. This carburetor is not designed to work with ANY other automatic overdrive transmissions.
These carburetors have been designed and calibrated as a universal replacement carburetor for passenger cars and light truck applications equipped with V-6 and V-8 engines. It is designed for use on “square” flange intake manifolds. Carburetor adapters are not recommended to adapt to “spread” bore intake manifolds, since adapters may have an adverse affect on cylinder-to-cylinder distribution and ultimately, total engine performance. However, some manifolds may be universal (such as Weiand 8004). Please check with Holley’s Avenger Technical Service Department if you have any questions.
REMOVAL:
1. Remove the air cleaner, exercising care to carefully detach any vacuum lines to the air cleaner and marking them so they can be reassembled to the air cleaner in the same manner.
2. Remove the existing carburetor by the following procedure:
A. Carefully disconnect the fuel line.
WARNING: Carefully protect the open end of the fuel lines, so that no foreign particles can enter. Wrap the end of the fuel line with a clean lint-free cloth.
B. Disconnect and mark all the vacuum lines to the carburetor.
C. Disconnect the PCV hose.
D. Disconnect the choke rod or heat tubes (if equipped).
E. Disconnect and remove the throttle linkage and automatic kickdown linkage. SAVE ALL RETAINING CLIPS.
F. Unbolt and remove the carburetor from the manifold.
3. If the intake manifold is being changed at this time, install the new manifold according to the manifold’s manufacturer’s directions. Since we are not familiar with all manifold instructions, Holley cannot accept responsibility for their validity. We recommend that you only use Holley Street Avenger manifolds, which you can find in the Street Avenger catalog included with your kit.
