SBF Performer RPM A/G Manifold - 351C

The EDELBROCK SBF Performer RPM A/G Manifold for 351C is a high-performance dual-plane intake manifold engineered for Ford Cleveland and modified engines requiring optimized air-gap architecture. This aluminum manifold delivers improved volumetric efficiency and thermal management compared to conventional designs, making it a preferred choice for serious engine builders targeting increased horsepower and torque output in both street and competition applications.

Built from lightweight aluminum construction with natural finish, the RPM Air-Gap design features a square-bore configuration that maximizes airflow characteristics across the intake runners while reducing heat transfer from the engine block. The dual-plane intake design optimizes low-to-mid-range torque delivery, a critical consideration for engine packages requiring broad powerband response. At 22.1 pounds, this manifold provides a significant weight reduction compared to cast-iron alternatives, contributing to overall vehicle performance and handling dynamics.

This manifold addresses the requirements of engine enthusiasts and professional builders working with 351C platforms—whether building a street machine, weekend cruiser, or competition-oriented powerplant. The RPM Air-Gap architecture is particularly suited for applications where consistent mid-range power matters more than peak high-rpm horsepower, making it ideal for vehicles prioritizing drivability and responsiveness. The square-bore design ensures compatibility with properly-matched carburetors and fuel injection systems common to 351C engine conversions and restorations.

EDELBROCK's RPM series represents decades of intake manifold engineering focused on real-world performance gains verified through dyno testing and road validation. The air-gap principle—an air space between the plenum and the mounting surface—reduces heat soak into incoming charge air, supporting cooler, denser fuel mixtures that contribute to measurable performance improvements across the operating rpm range.
