BBM Dual Quad Manifold - 413-426-440

The Edelbrock BBM Dual Quad Manifold for 413-426-440 engines is a purpose-built intake solution designed for enthusiasts and professionals who demand maximum fuel distribution and cylinder charging efficiency in Chrysler RB-series big-block applications. This manifold is ideal for those looking to enhance performance in vintage muscle cars or high-performance builds.

Constructed from lightweight aluminum in a natural finish, the BBM dual quad manifold features a square-bore design optimized for Mopar RB-series engines including the 413, 426, and 440 cubic inch variants. The dual-quad configuration distributes intake charge independently to each carburetor stack, reducing fuel pooling and ensuring more uniform cylinder filling compared to single four-barrel setups.

This manifold serves engine builders, restoration shops, and vintage muscle car operators seeking authentic or enhanced carburetor induction for Chrysler RB blocks. Installation requires proper gasket sealing and verification of carburetor synchronization to achieve optimal idle quality and transition response.
