DESCRIPTION:
The Edelbrock Performer RPM Air-Gap manifold is a carbureted intake manifold that has been designed specifically for 5.2L & 5.9L
Chrysler Magnum engines. The manifold accepts carburetors only, and will not function with the factory fuel injection system. It is intended for use
in engine swap applications in which a Magnum engine is being used in an early vehicle application. The Performer RPM Air-Gap 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:
Intake manifold will not accept stock EGR (Exhaust Gas Recirculation) equipment. EGR systems are used on most 1972 and later
model vehicles. Check local laws for requirements.
•
CARBURETOR RECOMMENDATIONS:
NOTES:
Carburetor size (CFM) should be selected based on your specific engine combination. Consult your engine builder or contact our Technical
Hotline at: 1-800-416-8628 for assistance. Carburetors require a #8008 or #8024 stud, washer and nut kit; determine proper length based on
gasket thickness and your accessory mounting requirements (See catalog for details). If a manual choke Performer Series Carburetor is used and
electric choke is desired later on, Performer Series carburetors can be converted to electric choke using Electric Choke Kit #1478. Manual choke
Thunder Series carburetors CAN NOT be converted to manual choke.
