Chevy 348-409 Performer RPM Intake Manifold

The Chevy 348-409 Performer RPM Intake Manifold by Edelbrock is purpose-built for big-block Chevrolet enthusiasts seeking maximum engine efficiency and power gains. Designed specifically for the legendary 348 and 409 cubic-inch engines, this intake manifold addresses the breathing limitations of stock castings that restrict airflow to the combustion chambers.

Edelbrock engineered this manifold with dual-plane runner geometry and optimized port matching to maximize velocity and scavenging efficiency across the RPM band. The Performer RPM design leverages Edelbrock's racing heritage, featuring superior casting quality and precise machining to ensure consistent fuel distribution and reduced turbulence. The 23-pound aluminum construction provides a weight savings advantage over cast-iron alternatives while maintaining thermal stability under sustained boost conditions.

Serious big-block builders and restorers will appreciate the manifold's geometry, which is specifically calibrated for the unique port locations and combustion chamber designs of 348 and 409 blocks, ensuring proper alignment and gasket sealing. Whether you're building a high-performance street engine or restoring a classic Chevrolet muscle car, the Performer RPM delivers the airflow optimization needed to unlock your big-block's full potential.
