BBM 440 Valley Plate Assembly

The Trick Flow BBM 440 Valley Plate Assembly is a crucial component for enthusiasts and engine builders working with the legendary Mopar RB-Series big block. Specifically engineered for the 440 cubic inch platform, this assembly provides a professional sealing solution when utilizing high-performance intake manifolds that do not feature an integrated valley cover. Whether you are looking to buy a replacement for a worn factory part or completing a custom build, this kit ensures your lifter valley remains protected from debris and oil spray. Reviewing your engine's sealing requirements is essential before installation to guarantee optimal performance and long-term durability.

Constructed from high-strength aluminum, this valley cover offers significant advantages over traditional stamped steel alternatives. The natural finish provides a clean, industrial aesthetic that complements any high-performance engine bay while resisting the warping often associated with heat cycles. This assembly is designed to work as a comprehensive kit, providing the necessary rigidity to maintain a consistent seal across the engine block. By utilizing a thicker plate design, the unit minimizes the potential for vacuum leaks and oil seepage in high-stress racing or demanding street applications where specifications for fitment are tight.

This assembly is primarily intended for owners of Mopar RB-Series engines who require a dedicated valley cover that is independent of the intake manifold. It is particularly beneficial for those running aftermarket cylinder heads and intakes where precise fitment is a priority for maintaining oil control. Installation is straightforward for those familiar with Big Block Mopar specifications, making it a staple for professional restoration and performance shops. Integrating this plate into your build ensures long-term reliability and a cleaner internal engine environment for your high-displacement Mopar power plant.
