BBC S/W Intake Manifold - Oval Port

The WEIAND BBC S/W Intake Manifold - Oval Port is a specialized component designed for big-block Chevrolet engine builders who prioritize reliable mid-range torque and street performance. This single-plane intake is ideal for applications where stock or mildly ported cylinder heads require efficient fuel mixture distribution without the added complexity of dual-plane geometry.

Engineered for optimal performance, the oval port design enhances flow velocity through the intake runner passages, minimizing turbulence and ensuring an even air-fuel charge distribution to all eight cylinders. The single-plane configuration is tailored to favor broader torque curves, making it particularly suitable for street engines where driveability and response are prioritized over peak horsepower.

This manifold is compatible with stock-to-moderately ported BBC cylinder heads and carbureted fuel systems, making it a preferred choice for hot rod builders and restoration enthusiasts. Weighing approximately 19.84 lbs, it maintains structural integrity while being lightweight enough not to impose excessive mass on your BBC block.
