BBC Power+Plus PS Manifold - Satin

The BBC Power+Plus PS Manifold - Satin from Professional Products is engineered for serious big-block Chevy builders who demand maximum scavenging efficiency and reliable performance across the RPM band. This cast-iron manifold is designed to replace restrictive factory units, unlocking horsepower that OEM designs leave on the table. Whether you're building a street engine, bracket racer, or high-performance cruiser, this manifold serves as the foundation for effective exhaust management and improved cylinder breathing.

The Power+Plus design incorporates optimized runner geometry that minimizes turbulence and promotes smooth exhaust gas evacuation, reducing backpressure without sacrificing low-end torque. Cast from ductile iron and finished in a heat-resistant satin coating, the manifold resists corrosion while maintaining a clean aesthetic. The satin finish also provides better thermal emissivity than glossy alternatives, helping dissipate heat more effectively in tight engine compartments. At 19.95 lbs, the manifold is substantial enough to handle aggressive tuning while remaining practical for street and competition applications.

Big-block Chevy enthusiasts—from 396 through 454 platforms—benefit most from this upgrade when paired with a quality header or exhaust system. Installation is straightforward for experienced mechanics; standard bolt-on fitment integrates with most BBC engine blocks without modification. The manifold's robust construction handles both naturally aspirated and moderately boosted applications, making it a versatile choice for builders planning future upgrades. Verify exhaust outlet diameter and bolt pattern against your specific BBC variant before purchase to ensure seamless integration.
