• DESCRIPTION:
Edelbrock Performer intake manifolds are designed for 396-502 c.i.d. big-block Chevy engines operating in the idle to 5500 rpm range.
Performer RPM and RPM Air-Gap intake manifolds are designed for 396-502 c.i.d. big-block Chevy engines operating in the 1500-6500 rpm
range. In most cases, these manifolds accept late model water necks, air conditioning, alternator and H.E.I. ignition systems. Any exceptions
are listed in the “Applications” section below. Match Performer or Performer RPM intake manifolds with recommended carburetors and
additional equipment for even greater performance increases.
APPLICATIONS:
INTAKE MANIFOLD REFERENCE APPLICATION
2161, 3761 B, C, E Performer 2-O: Designed for street 396-502 c.i.d. big-block Chevy V8s using general
duty oval-port cylinder heads. Will fit 1965-1990 oval-port heads. Not for “tall block”
V8s. Use #8028 waterneck adapter for 1986 and later. Choke plate #8961 included.
7161, 7163 A, C, D, E Performer RPM 2-O and 2-R: 7161 is designed for 396-502 c.i.d. Chevy V8s with large
oval-port cylinder heads (1975 and earlier). No provisions for exhaust heated chokes.
Not for “tall block” V8s. 7163 is similar to 7161, but is designed to fit high performance
rectangular-port cylinder heads. Will not fit oval port heads.
7164 A, C, D, E Performer RPM Q-Jet: Designed for street 396-502 c.i.d. Chevy V8s with large oval-port
cylinder heads (1975 and earlier) using spread-bore carburetors. Also accepts Edelbrock
square-bore carburetors without requiring an adapter. Will accept divorced choke. Not
for “tall block” V8s.
7561, 7562, 75613 A, C, D, E RPM Air-Gap 2-O and 2-R: 7561 is designed for 396-502 c.i.d. Chevy V8s with large
oval-port cylinder heads (1975 and earlier). Air-Gap designs separate the runners from
the hot engine oil resulting in a cooler, denser charge for more power. Features rear
water outlets, two distributor clamp locations, and nitrous bosses. No provisions for
exhaust heated chokes or exhaust crossover. 7562 is similar to 7561, but is designed
to fit high performance rectangular-port cylinder heads. Will not fit oval port heads.
A- Not legal for sale or use on pollution controlled motor vehicles.
B- Stock replacement/street legal in some applications. See “Stock Replacement Parts List for Intake Manifolds” insert, or Catalog for details.
C- Will not fit under stock Corvette hood.
D- Will not fit under stock 1965-1967 Chevelle or 1967-1981 Camaro hood.
E- Available in additional finishes, such as polished, PermaStar, or EnduraShine. See Catalog for details.
• EGR SYSTEMS: Edelbrock EGR-equipped
Performer
manifolds are intended as a direct functionally identical replacement for their O.E.M.
counterparts. All exhaust emissions or emissions related stock components are intended to be retained and functional. Non-EGR equipped
manifolds will not accept stock EGR (Exhaust Gas Recirculation) equipment. EGR systems are used on most 1972 and later. Check local laws
for requirements.
• ACCESSORIES & INSTALLATION ITEMS: Major recommendations are listed below. See our catalog for details. To order a catalog, call

• CARBURETOR RECOMMENDATIONS:
Manifold 2161, 3761 (Emissions Controlled Applications):
Manifold 2161 (Non-Emissions):
Manifold 7161, 7163, 7561, 7562, 75613 (Non-Emissions):
• THROTTLE BRACKETS: Due to the design of Performer manifolds, the throttle and kickdown bracket on some vehicles may require
modification to fit. See figure 1 for guidelines or purchase our #8031, 8030 or 8036 throttle, cruise, and kickdown linkage brackets
• GASKETS: Do not use competition style intake gaskets for this street manifold. Due to material deterioration over time, internal leakage of
vacuum, oil, and coolant may occur.
A-Carburetor will work with non-EGR or pre-emission control systems.
B-Carburetor will work with EGR system.
H-Carburetor has provision for evaporative canister.
I-Carburetor has no provisions for evaporative canister.
K-Carburetor requires #8008 or #8024 stud, washer and nut kit. Determine proper length based on gasket thickness and your accessory
mounting requirements.
N-Carburetor accepts factory cruise control
O-Carburetor comes with manual choke. It can be converted to electric choke using kit #1478.
P-Carburetor is not a stock replacement part
