BBM Aluminum Motor Plate

The Chassis Engineering BBM Aluminum Motor Plate (Part Number C/E3702) is a precision-engineered front motor plate designed specifically for Mopar B-Series, RB-Series, and 426 Hemi engines. Constructed from natural aluminum, this 36 x 12 x 0.25-inch plate provides the rigid structural foundation required for high-performance engine installations, custom builds, and restoration projects. The aluminum construction delivers the optimal balance of strength and weight savings essential for serious engine swap work and vintage muscle car restorations.

At 9.35 lbs, the BBM plate's substantial mass and precise dimensions ensure proper engine-to-chassis alignment while maintaining minimal additional weight. The 0.25-inch aluminum thickness provides sufficient structural rigidity for motor mounts, while the full 36-inch length accommodates the extended footprint of B and RB block engines. The natural finish accepts paint or powder coating, allowing seamless integration into custom engine bay aesthetics. Chassis Engineering's manufacturing standards ensure consistent geometry across production, critical for reducing vibration and ensuring durable engine mounting.

This motor plate is essential for builders undertaking Mopar engine conversions, restoration shops reassembling original or modified vehicles, and performance enthusiasts upgrading to B-block or RB-block powerplants. Whether restoring a classic 1970s Dodge or building a street rod around a 426 Hemi, proper engine mounting hardware prevents resonance, protects engine bay components, and ensures safe longitudinal engine security. The plate's compatibility with Mopar's iconic big-block lineup makes it an indispensable foundation component for authentic or upgraded Mopar installations.
