Show original supplier description
The Edelbrock CH-6B Six-Pack intake manifold is a high-performance, dual-plane aluminum component specifically designed for Chrysler RB series (Wedge) engines, including 413, 426, and 440 cubic inch displacements. Engineered for optimal performance between 2500-6500 RPM, this manifold accepts three 2-barrel carburetors, mirroring the original equipment found on Chrysler 440 Six-Pack engines. It is a direct fit and street-legal replacement for 1968-1971 Chrysler 440 V8 models utilizing OEM 3x2-barrel carburetors. Installation requires attention to specific details. It is recommended to use Edelbrock intake gasket #7225. The manifold measures 4.875" (A) and 5.63" (B) in height, with a carburetor pad height of 5.25". The port exit dimensions are 1.10" x 2.12". For sealing end seals, use RTV sealant such as Edelbrock High Temp Silicone sealant #1076, and avoid end seal gaskets. Additionally, hardened washers must be used with intake bolts to ensure proper torque and prevent galling of the aluminum. Important fitment notes: This manifold will not fit 1962-1964 Max Wedge cylinder heads.
