Steel Mid Plate Chevy SB /BBC/LS/LT Rear Motor

The ICT Billet Steel Mid Plate for Chevy SB/BBC/LS/LT rear motor applications is a precision-engineered motor plate designed for engine builders and hot rod fabricators working with GM V8 powerplants. This mid-mount steel plate (SKU ICT551809, MPN 551809) provides a rigid, cut-to-fit foundation for securing rear motor accessories, engine cooling systems, and transmission-mounted components in custom engine bay configurations.

Manufactured from natural steel with a thickness of 0.5 inches and dimensions of 36 × 12 inches, this plate weighs 14.23 lbs and delivers the structural integrity required in high-vibration environments. The cut-to-fit design allows fabricators to modify hole placement and cutouts to match specific engine bay layouts, transmission tunnel geometry, and accessory mounting requirements. The generous 36-inch length accommodates both traditional small-block and large-displacement LS/LT configurations, while the flat steel surface provides a reliable datum plane for precision drilling and alignment during assembly.

This motor plate is ideal for custom fabricators, engine builders, and restoration specialists working on GM V8 conversions, engine swaps, and performance builds. Whether adapting a small-block Chevy to an older chassis, mounting an LS or LT powerplant in a custom frame, or reinforcing rear motor support in a race application, this plate serves as the structural backbone for reliable engine mounting. The natural steel finish allows welding and paint-over compatibility without surface preparation complications, making it suitable for both street and competition use.
