Edelbrock Performer RPM intake manifold for 1965-up Oldsmobile 400-425-455.







This high-flow manifold produces broad torque and peak horsepower in the 1500 to 6500 RPM range and features an Air-Gap design. This award-winning design incorporates the same race-winning technology that's been used on Edelbrock Victor Series competition intake manifolds. The Air-Gap design features an open air space that separates the runners from the hot engine oil, resulting in a cooler, denser charge for more power. Not compatible with EGR or spread-bore carburetors.

SPECIAL INSTRUCTIONS FOR MARINE AND COMPETITION APPLICATIONS - PLEASE NOTE: Any implied or expressed warranty is void unless the “Special Exhaust Plugs” are used with your engine. These steel plugs are furnished with each Performer 455 manifold and must be installed in the exhaust crossover port in each head. These plugs prevent cracking of the manifold caused by extreme heat of the exhaust during extended periods of Wide Open Throttle. Use a file to finish and fit the plugs until they are a light drive fit. With a small hammer, tap them into each head until they are flush (to prevent vacuum leaks). Additional plugs may be purchased under Edelbrock #2733. For Heavy Vehicles (RVs, etc.) - Use the Special Exhaust Plugs supplied. However, drill a 1/4"-5/16" hole through each plug before installation. This step is highly recommended for all applications!
