INSTALLATION INSTRUCTIONS
APPLICATIONS:
The P/N 701-1BD BLACK DIAMOND® intake manifold is designed for square-bore carburetor applications on 1957-86
262-400cid Small Block Chevrolet engines and SBC engines equipped with 1987-91 L98 aluminum Corvette cylinder heads
(non-EGR applications). Also, this manifold will work with any SBC engine equipped with aftermarket cylinder heads, as long as
they have a standard port flange opening and bolt hole locations.
This 180° dual plane intake manifold is designed to provide the best performance for stock to street-performance engine
applications to a maximum engine speed of 5500 RPM. The carburetor-mounting pad is designed to accept all stock or
aftermarket square-bore carburetors with manual or electric chokes. BLACK DIAMOND® intake manifolds are designed to
accept most stock hardware, such as coolant and vacuum lines, coils, HEI distributors, and brackets. Few alterations, if any,
should be required.
EMISSIONS EQUIPMENT:
P/N 701-1BD does not accept an EGR valve, hot-air, or divorced chokes. This part is not legal for sale or use for motor
vehicles with pollution-controlled equipment.

PRELIMINARY CHECKLIST:
Carefully read and understand these installation instructions.
Check that this intake manifold is the correct choice for your engine application, desired performance level, and local
emissions laws. This intake manifold will require a manual or electric carburetor choke.
Inspect the manifold for any damage that may have occurred during shipping. If damaged, contact your dealer immediately.
Check that all of the parts listed in the Kit Contents list in these instructions have been included with your intake manifold.
Inspect all threaded holes.
Inspect all internal passages with a light and a stiff wire to be sure that the passages are not obstructed and have
been properly cleaned to be free of any debris.
Check for sufficient hood clearance with this intake manifold and intended carburetor/air cleaner combination to be used.
Check that you have all of the parts required for the installation. These include the intake manifold gasket set, gasket
adhesive, RTV silicone sealant, and pipe thread sealant as shown in the Parts Required list in these installation instructions.
Check that you have all the tools you will need to perform the intake manifold installation. A recommended but not
exhaustive list is located in these installation instructions.
Check that you have the proper intake manifold fasteners for this application.
If using your old carburetor, before you remove it from the engine make sure it is working properly and that the carburetor is
tuned properly. Consult the shop manual or installation instructions for that carburetor to determine if the carburetor is in
proper tune.

If you are using a new carburetor, make sure you have read and understand the installation instructions for that carburetor
and that the initial adjustments are within the manufacturer’s specifications.
Before removing your old intake manifold, make sure that your ignition system is in good working order; check and note the
current ignition timing. Make sure that the timing marker is legible and understandable. With the engine at top dead center
on the #1 cylinder, note and mark the orientation of the distributor body to the engine and the orientation of the rotor to the
distributor body. This will aid in the re-installation of the distributor. Consult these installation instructions and your vehicles
shop manual for specific instructions.
Before removing your old intake manifold check the adjustment of your automatic transmission kick-down linkage to make
sure it is adjusted properly. Consult your shop manual and make sure that you understand the kick-down linkage
adjustment and how to properly adjust it when you install your new intake manifold.
Before removing your old intake manifold check all of your fuel, water, and vacuum hoses and their connections. Make
sure that there are no leaks and that the hoses are in good condition. Mark the locations of your hoses making sure that
there is a corresponding location on your new intake manifold for all of the hose fittings and gauge sensors. Fitting and
hoses that are not in good condition should be replaced.
