BBM 440 Intake Manifold 4150 Flange

The BBM 440 Intake Manifold 4150 Flange is a high-performance aluminum intake manifold designed specifically for big-block Mopar engines, particularly the 440 cubic-inch platform. This manifold is ideal for builders and enthusiasts aiming to enhance airflow, fuel atomization, and power output in carbureted or fuel-injected setups using a 4150-pattern carburetor flange.

Constructed from aluminum, the BBM 440 manifold balances weight savings with durability while promoting even distribution across all eight cylinders. Its runner geometry is optimized for 440 displacement, which improves scavenging and reduces heat retention compared to stock iron manifolds. The aluminum material also aids in maintaining cooler intake charge temperatures, crucial for consistent combustion in high-output applications.

This manifold is perfect for Mopar enthusiasts, restorers, and performance shops building 440-powered engines for street, strip, or show applications. The compatibility with the 4150 flange format ensures seamless integration with standard four-barrel carburetor adapters and modern fuel-injection systems, eliminating the need for costly modifications.
