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 aluminum intake manifold accommodates dual four-barrel carburetors, delivering the balanced air-fuel mixture critical for sustained high-RPM performance and reliable throttle response across demanding operational conditions.

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. At 20.9 lbs, the manifold's aluminum construction minimizes parasitic weight while maintaining structural integrity under high boost and sustained combustion loads inherent to performance and law enforcement pursuit vehicles.

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. The compact footprint (15 × 7.5 × 23.75 inches) ensures compatibility with stock and modified engine bay configurations, though hood clearance and fuel line routing should be verified before final assembly.
