Olds Performer Manifold - 400-455

The Edelbrock Olds Performer Manifold for 400–455 Oldsmobile V8 engines is a dual-plane aluminum intake manifold engineered to deliver efficient fuel distribution and consistent air velocity across a broad RPM range. Part number 2151, this spread-bore configuration integrates proven Edelbrock tuning to maximize torque production in street and light competition applications while maintaining the durability expected from cast-aluminum construction.

Weighing 26.46 pounds with dimensions of 15.35 × 8.05 × 24.05 inches, this manifold is designed as a direct bolt-on for compatible Oldsmobile big-block engines. The dual-plane design separates cylinders into upper and lower intake runners, reducing heat transfer to the incoming charge and improving volumetric efficiency—a critical factor for operators seeking consistent power delivery across varying load conditions. The spread-bore bore pattern accommodates factory-spec carburetor mounting, simplifying installation and compatibility with existing fuel delivery systems.

This intake manifold serves enthusiasts and restoration specialists working with Oldsmobile 400, 425, and 455 cubic-inch V8 powerplants. Whether applied to classic muscle car restorations, period-correct street machines, or high-torque street performance builds, the Performer series delivers the thermal management and flow characteristics required for reliable operation. The natural aluminum finish resists oxidation and integrates with stock engine bay components without requiring cosmetic modification.

Edelbrock's Performer line represents a proven balance between OEM compatibility and enhanced volumetric efficiency—positioning this manifold as a preferred upgrade for Oldsmobile big-block restoration and performance work. The dual-plane geometry suits low-to-mid RPM torque emphasis, making it ideal for street applications where driveability and throttle response matter more than peak RPM performance.
