SBC Power+Plus PS Manifold - Satin

The SBC Power+Plus PS Manifold in satin finish is a dual-plane intake manifold engineered for Small Block Chevy engines, designed to optimize mid-range torque and throttle response in both street and performance applications. Built by Professional Products, this aluminum component replaces restrictive factory manifolds and serves as the foundation for improved airflow distribution across all eight cylinders. Whether you're upgrading a daily driver or refining a weekend warrior build, this manifold delivers measurable gains in drivability and power delivery without requiring extensive engine modifications.

Constructed from lightweight aluminum with a professional satin finish, the Power+Plus design incorporates a dual-plane runner architecture that separates firing pulses and maximizes volumetric efficiency across a broad RPM band. The spread-bore configuration accommodates both square-bore and spread-bore carburetors, offering compatibility flexibility for different fuel delivery systems. Precision casting and port matching minimize turbulence and dead zones, allowing cooler, denser charge air to enter each cylinder chamber with minimal restriction—a critical factor in extracting consistent power from naturally aspirated small-block platforms.

This manifold is ideal for Small Block Chevy builds ranging from 265 to 400-cubic-inch displacements, making it suitable for Chevrolet and General Motors vehicles from the 1950s through early 2000s. Installation requires basic mechanical competency and standard hand tools; ensure proper gasket sealing and torque specifications are followed for leak-free operation. The satin aluminum finish resists oxidation while maintaining a professional appearance under the hood, and its 16.1-pound weight contributes minimal parasitic mass compared to factory iron alternatives.
