SBF Performer RPM Dual Quad A/G Manifold - 351W

The SBF Performer RPM Dual Quad A/G Manifold - 351W from Edelbrock is a high-performance intake manifold engineered specifically for small-block Ford 351W engines seeking maximum flow and power across the RPM band. This dual-quad design accommodates two four-barrel carburetors, making it the go-to choice for serious hot rod builders, street machine enthusiasts, and weekend warriors who demand authentic performance from classic Ford platforms. Whether you're building a restomod Mustang, a high-output truck engine, or a competition drag car, this manifold delivers the intake geometry needed to support aggressive carburetor tuning and realistic power gains.

Edelbrock's Performer RPM series is renowned for optimized port matching and velocity management that balances low-end torque with peak horsepower delivery. The dual quad configuration distributes fuel charge evenly across all eight cylinders, eliminating the fuel distribution compromises of single-carb systems and allowing each runner to breathe at full potential. Cast aluminum construction provides excellent heat dissipation while keeping weight down—critical for both street handling and competition applications. The manifold's design supports both air gap and gasket mounting styles, offering flexibility during installation and allowing tuners to optimize cold-start characteristics and underhood temperatures based on their specific build requirements.

This manifold is ideal for 351W engine platforms running carbureted fuel delivery—whether naturally aspirated or moderately boosted on the street. Installation requires compatible dual-quad carburetors (typically 500–650 CFM units), quality fuel lines, and proper jetting and tuning for optimal results. The 351W's increased displacement makes it an excellent platform for this manifold, and experienced builders often pair it with high-flow cylinder heads, a solid roller camshaft, and a performance ignition system to unlock 400+ horsepower reliably. Before purchasing, verify your engine block casting number and ensure your fuel system, cooling capacity, and carburetor selection align with dual-quad induction demands.
