4500 Single Plane Intake Manifold BBF Bullitt

The 4500 Single Plane Intake Manifold BBF Bullitt (Part #4993) is a purpose-built aluminum intake assembly designed specifically for Big Block Ford applications that demand maximum airflow and performance. Engineered for serious engine builders, this intake manifold is ideal for high-RPM performance, making it suitable for street performance, racing, or restoration builds.

This single-plane design features a Dominator flange configuration, ensuring direct bolt-on compatibility with standard BBF cylinder heads. The aluminum construction provides a verified weight of 27.42 lbs, which helps reduce overall engine bay mass while maintaining structural integrity under various operating conditions. The natural (uncoated) finish allows builders to customize the appearance or apply thermal coatings as needed.

Builders targeting maximum displacement from 460 or 429 cubic inch blocks will find this intake manifold particularly beneficial, as it excels in applications above 5,000 RPM. The design prioritizes equal fuel distribution and air charge across all cylinders, which directly impacts power output and driveability. While the compact footprint (14.45 × 9.85 × 25.55 inches) is designed to fit in tighter engine compartments, it is essential to verify compatibility with specific engine setups.
