AMC Performer Manifold - 290-401

The Edelbrock AMC Performer Manifold 290-401 is a dual-plane aluminum intake manifold designed specifically for AMC V8 engines ranging from 290 to 401 cubic inches. This manifold is ideal for automotive enthusiasts seeking enhanced throttle response and improved mid-range torque while maintaining street drivability. It serves as an excellent upgrade for classic models like the Javelin, Rebel, or Hornet, making it a popular choice for restoration and performance modification projects.

The dual-plane design of the manifold optimizes cylinder charge distribution across the RPM range, ensuring strong low-end response and stability at highway speeds. This is particularly important for street-driven AMCs that require consistent throttle modulation. Constructed from lightweight aluminum, this manifold reduces engine bay heat and enhances overall cooling efficiency compared to traditional cast-iron units.

The AMC Performer Manifold fits AMC 290, 304, 343, and 401 V8 engines and is compatible with both single-plane and dual-plane carburetors via standard two-inch throttle body mounts. Installation is straightforward, requiring no welding or extensive modifications, as the gasket surfaces align directly with factory cylinder heads. This makes it suitable for stock to mildly modified engine combinations, ensuring optimal fuel atomization and air velocity.
