BBC Intake Manifold - 9.800 R/P 4150 Flange

The BBC Intake Manifold 9.800 R/P 4150 Flange is a single-plane aluminum intake manifold engineered for big block Chevy applications requiring precise port alignment and high-flow efficiency. Designed with a square bore configuration and rectangle port geometry, this naturally finished aluminum casting delivers the foundation for optimized fuel-air mixture distribution across the cylinder heads. At 23.55 lbs, the manifold's weight-to-rigidity ratio supports both carbureted and fuel-injected big block builds without compromising structural integrity or thermal stability.

The single-plane design concentrates runner lengths for peak volumetric efficiency at higher RPM ranges, making this intake manifold a preferred choice for street performance and competition engines targeting sustained power delivery above 5,000 RPM. The 4150 flange pattern ensures compatibility with standard carburetor mounting and adapter systems. Rectangle ports maximize flow characteristics compared to siamesed runner designs, reducing restriction and supporting larger displacement combinations. The aluminum construction resists corrosion better than cast iron while managing heat transfer effectively during extended operation. Dimensions of 13.05 x 8.25 x 23.25 inches accommodate tight engine bay installations while maintaining adequate plenum volume for cylinder scavenging.

This intake manifold suits builders developing naturally aspirated big block Chevy engines for street, bracket racing, and off-road applications where mid-to-high RPM power bands demand superior intake velocity and distribution. The part number 41114000 (UPC 807051025637) represents a verified OEM or OEM-equivalent specification. Buyers should confirm carburetor size, fuel delivery method, and engine displacement compatibility before installation. The natural aluminum finish can be painted or powder-coated to match engine bay aesthetics or thermal management requirements.
