CATALOG #2921
INSTALLATION INSTRUCTIONS
Please study these instructions carefully before installing your new intake manifold. If you have any questions or problems,
please call our Technical Hotline at: 1-800-416-8628, 7:00 am - 5:00 pm, Monday through Friday, Pacific Standard Time,
or e-mail us at [email protected]
• MANIFOLD: These manifolds are designed for competition vehicles only and are not intended to be used on the street as
they do not have provisions for chokes, emission pieces, etc. The #2921 is designed for use with the Victor Jr. cylinder heads
or early (’69, ’70, & ’71) ported factory cast iron 289, 302, or 351W cylinder heads. Aftermarket aluminum heads are highly
recommended.
NOTE: This manifold has no provision for power brake vacuum. If your application requires manifold vacuum, drill and tap
a 3/8” or 1/4” pipe hole in the passenger side of the plenum as close to the carb flange as possible. This should be done
prior to installing the manifold.
• ACCESSORIES & INSTALLATION ITEMS: Edelbrock recommends the use of Fel-Pro Intake gaskets #1250 or #1262
depending on engine build. Edelbrock continues to expand its line of products, like the new Nitrous Systems, cylinder heads
and Russell line of products. Check the Edelbrock catalog and website for the current list of matching components.
• CARBURETOR RECOMMENDATIONS: Standard square bore carburetors 750 cfm or larger.
• PREP AND TUNING FOR POWER: Optimum cylinder head port opening size should be as close as possible to the size of
the gasket being used. Port-match the manifold exits .020" per side

smaller than either the gasket being used or the cylinder head port
opening, whichever is smaller.
• MANIFOLD TORQUE - WARNING: On early model heads, there is no
support underneath manifold boltholes circled 5, 6, 7, and 8. These
bolts need to be hand-tightened with a short box end wrench being
very careful not to damage the manifold. Torque all other bolts in the
sequence to 15-18 ft-lbs.
• CARBURETOR SPACERS: Some applications may benefit from a oneinch open carburetor spacer such as Edelbrock #8710. This normally
requires slight recalibration of the carburetor since small losses of fuel
signal cause the engine to run somewhat leaner than without the
spacer. A simple jet change is typically all that needs to to be done.
NOTE: With some race distributors, the fins on one side of the
distributor might hit the water jacket or thermostat housing on the
manifold. If necessary, trim the fins on one side of the distributor slightly
to allow clearance.
PLEASE complete and mail your warranty card. Be sure to write the
model number of this product in the “Part #_____” space.
