DESCRIPTION: The Edelbrock RPM Air-Gap #7116 intake manifold has been designed for 262-400 c.i.d. small-block
Chevy engines equipped with Vortec style (L31) cylinder heads. The manifold accepts late model water neck, air
conditioning, alternator and H.E.I. ignition systems. Use electric or manual type choke square bore carburetors only. This
intake manifold is recommended for street high performance, marine and race vehicles (where dual plane manifolds are
required). The RPM manifold provides good low rpm response for street performance vehicles while providing increases
in horsepower and torque up to 6500 RPM. When used with any mix of aftermarket equipment designed for this
operating range, the performance increases will be even greater.
EGR SYSTEMS: This manifold will not accept stock EGR (Exhaust Gas Recirculation) equipment or exhaust-heated
chokes. EGR systems are used on some 1972 and later model vehicles and only in some states. Check local laws for
requirements. This manifold is not legal for use on any emissions controlled vehicle where such equipment is required.
ACCESSORIES & INSTALLATION ITEMS: Major recommendations are listed below. However, due to the variety of
years, makes and models to be covered, please review each part listed in the Installation Items section of the Edelbrock
catalog to decide whether more items are required for your specific vehicle than are mentioned in these instructions. See
our catalog for details. To order a catalog, call (800) FUN-TEAM.
CARBURETOR RECOMMENDATIONS:
CARBURETOR REFERENCE PARTS REQUIRED FOR INSTALLATION
Performer #1407 (750 cfm)
A, I, K, O
Performer #1411 (750 cfm)
A, I, K
Performer #1412 (800 cfm)
A, I, K, O
Performer #1409 (600 cfm)
or #1410 (750 cfm) marine
A,I,K
A – Carburetor will work with non-EGR or pre-emission control system.
I – Carburetor has no provisions for evaporative canister.
K – Carburetor requires #8008 or #8024 stud, washer and nut kit. Determine proper length for your carb to
manifold gasket thickness and your accessory mounting requirements.
O – Carburetor comes with manual choke. It can be converted to electric choke using kit #1478.
THROTTLE BRACKETS: Due to the design of Vortec style intake manifolds, throttle brackets designed to fit at the intake
manifold bolt bosses on a standard small block Chevy will not work. A throttle bracket that attaches to the carburetor or
carb flange will need to be used. This type of bracket is available from some aftermarket suppliers.
GASKETS: Use only an original equipment intake gasket set GM #12529094 when installing an Edelbrock 7116
intake manifold.
INSTALLATION INSTRUCTIONS
1) Use only a GM #12529094 intake gasket set when installing this intake manifold.
2) Fully clean the cylinder head intake flanges and the engine block end seal surfaces.
3) Install the intake gaskets to the cylinder head intake flanges. Two dowels on the intake manifold gasket will locate
into dowel holes in the cylinder head. Do not use any type of gasket sealer on the intake gaskets. The O-rings are
designed to seal without chemical sealers.
4) Do not use cork or rubber end seals. Use RTV silicone sealer instead. Apply a ¼” high bead across each block
end seal surface, overlapping the intake gasket at the four corners. This method will eliminate end seal slippage
and deterioration.
