BBC Intake Manifold - 10.200 R/P 4150 Flange

The DART BBC Intake Manifold - 10.200 R/P 4150 Flange is a precision-engineered aluminum intake solution designed for big block Chevy platforms requiring high-flow air delivery and extended port timing windows. Built to OEM specifications and tested in both street and competition environments, this single-plane manifold serves builders who demand reliable fuel distribution and maximum volumetric efficiency across a broad RPM band. Whether you're building a high-performance engine for drag racing, marine duty, or heavy-duty truck applications, this intake manifold provides the foundation for consistent, predictable combustion.

Manufactured from cast aluminum in natural finish, the BBC intake features a square-bore design with rectangle ports optimized for big block Chevy tall deck configurations. The 4150 flange pattern ensures compatibility with standard carbureted and fuel-injected setups, allowing seamless integration into existing fuel systems. At 26.9 lbs, the manifold strikes a balance between structural rigidity and weight savings—critical for applications where unsprung mass affects handling or where fuel economy matters. The single-plane design delivers fuel and air charge sequentially to each cylinder, reducing reversion and improving throttle response across the power band.

This manifold is ideal for experienced engine builders and performance shops specializing in big block Chevy restorations, crate engine assembly, and street/strip applications. Installation requires proper carburetor or fuel-injection adapter selection and careful gasket sealing to prevent vacuum leaks that degrade idle quality and part-throttle response. The tall deck compatibility makes this manifold suitable for modern big block builds using contemporary cylinder heads, while the rectangle port design accommodates both stock and ported cylinder head configurations without flow mismatch.
