BBM 440 Intake Manifold 4150 Flange

The BBM 440 Intake Manifold 4150 Flange by TRICK FLOW is a high-performance aluminum intake manifold engineered for big-block Mopar engines, specifically the legendary 440 cubic-inch platform. This manifold is essential for builders and enthusiasts looking to maximize airflow, fuel atomization, and power output on vehicles running carbureted or fuel-injected setups with a 4150-pattern carburetor flange. Whether you're building a vintage muscle car, a street rod, or a serious drag racing engine, the BBM 440 delivers the intake velocity and distribution characteristics needed to unlock significant horsepower gains.

TRICK FLOW's 440 manifold features precision-cast aluminum construction that balances weight savings with durability while promoting even distribution across all eight cylinders. The 4150 flange format ensures compatibility with standard four-barrel carburetor adapters and modern fuel-injection systems designed for this platform, eliminating costly modifications or adapter rings. The manifold's runner geometry is optimized for 440 displacement, delivering improved scavenging and reduced heat retention compared to stock iron manifolds. Aluminum construction also helps maintain cooler intake charge temperatures—critical for density and consistent combustion in high-output applications.

This manifold is ideal for Mopar enthusiasts, restorers, and performance shops building 440-powered engines for street, strip, or show applications. The 4150 flange compatibility makes installation straightforward on both classic carbureted platforms and modern EFI conversions, provided you use appropriate gasket sets and fasteners rated for aluminum-to-block interfaces. Proper manifold gaskets, ARP fasteners, and sealant application are essential to prevent coolant or vacuum leaks common with aluminum manifolds. At 19 lbs, the weight savings over cast-iron equivalents contributes to improved front-end weight distribution and reduced overall vehicle mass—meaningful advantages in both acceleration and handling.
