4500 Single Plane Intake Manifold BBF Bullitt

The 4500 Single Plane Intake Manifold BBF Bullitt (Part #4993) is a purpose-built aluminum intake assembly engineered for Big Block Ford applications requiring maximum airflow and performance. This single-plane design uses a Dominator flange configuration, allowing direct bolt-on compatibility with standard BBF cylinder heads while delivering the velocity and scavenging characteristics that serious engine builders demand.

Single-plane intake manifolds prioritize high-RPM performance by equalizing fuel distribution and air charge across all cylinders. The aluminum construction keeps weight to a verified 27.42 lbs, reducing overall engine bay mass while maintaining structural rigidity under boost or naturally aspirated operation. The natural (uncoated) finish allows builders to customize appearance or apply their own thermal coating without interference, and the compact footprint (14.45 × 9.85 × 25.55 inches) ensures clearance in tight engine compartments without sacrificing runner design.

This intake is favored by Big Block Ford engine builders working on street performance, racing, or restoration builds where peak horsepower and torque delivery matter. The single-plane configuration excels in applications above 5,000 RPM where manifold velocity and cylinder-to-cylinder fuel distribution consistency directly impact power output and driveability. Builders integrating forced induction or targeting maximum displacement from 460 or 429 cubic inch blocks find this design balances responsiveness with broad powerband support.

The Dominator flange standard simplifies carburetor and fuel injection mounting options, accommodating both traditional and modern fuel delivery systems. Proper gasket selection and torque sequence during installation ensure long-term sealing integrity under thermal cycling and pressure loads typical of performance applications.
