INTRODUCTION:
CONGRATULATIONS on your purchase of the Street HP™ Carburetor! We feel that you have purchased the finest street
performance carburetor manufactured today. Should you need information or parts assistance, please contact our HP Technical
Service Department at 1-866-GOHOLLEY (1-866-464-6553). Please have the part number and sales receipt ready when
calling.
IMPORTANT: The STREET HP™ carburetor has been factory wet-flowed and calibrated. The “out of the box” settings
should be very close for all adjustments.
To preserve warranty, these instructions must be read and followed thoroughly before and during installation.
NOTE: The Street HP Carburetor kit has not been submitted for emissions testing and therefore, has not received an Executive
Order Exemption from the California Resources Board. This means that your vehicle will NOT be “Smog Legal” in all 50
states with this kit installed.
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 geometry corrector (Holley® P/N 20-121).
Otherwise, SEVERE transmission damage WILL result. Depending on your accelerator bracket, you will
need one of the following throttle studs: Holley® P/N 20-2, 20-38, or 20-40. This carburetor is not
designed to work with ANY other automatic overdrive transmissions.
These carburetors have been designed and calibrated as a street performance carburetor for passenger cars and light truck
applications equipped with 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 HP 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.
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).
