BBC Intake Manifold - 9.800 R/P 4500 Flange

The DART BBC Intake Manifold – 9.800 R/P 4500 Flange is a high-performance single-plane aluminum intake designed for big block Chevy engines demanding peak volumetric efficiency at elevated RPM. Built from natural aluminum with a Dominator flange pattern and rectangle port design, this manifold channels air and fuel mixture directly into the combustion chambers with minimal turbulence, optimizing scavenging efficiency for engines wound tight to 4500 RPM and beyond.

Single-plane intake manifolds like this one excel in high-RPM, high-load scenarios where ram-air effect and intake velocity dominate fuel atomization. The 9.800-inch measurement references the critical port opening dimension—a specification that controls the transition from manifold to cylinder head and directly impacts the engine's breathing characteristics across the RPM band. The rectangle port configuration matches the standard big block Chevy head layout, ensuring precise port alignment and zero restriction at the fuel-air interface. At 23.3 pounds, this manifold adds minimal mass while providing the structural rigidity required for consistent performance under sustained full-throttle operation.

This manifold serves engine builders and experienced tuners running naturally aspirated big block Chevy platforms—from vintage muscle cars to custom truck engines—where every cubic foot of air per minute matters. Whether on the dyno, at the drag strip, or on the street, single-plane intake design delivers a sharp throttle response and builds power aggressively in the upper RPM range where most of the engine's work occurs. The natural aluminum finish allows for custom finishing to match engine compartment aesthetics without affecting thermal or operational characteristics.

DART is recognized in the performance engine community for precision casting and port work quality. This intake represents the type of component selection that separates a properly tuned engine from one left on the table. The Dominator flange standard ensures compatibility with aftermarket carburetors and fuel injection systems engineered for single-plane manifold mounting.
