$235.00 $189.00


Made from .125 thick steel, this mid plate will harness the engine to the chassis, which in turn reduces chassis rotation and will allow for better traction and faster elapsed times. Mid plates also significantly reduce block flex. By reducing the engine’s block flex you will prevent main bearing failure. Main bearing failure typically occures when the engine block flexes at the main web area. This flex is caused by the fastening of the block by it’s factory motor mounts solely. A must have for any Oldsmobile performance application. Recommended for applications from 500hp and up. This unique design incorporates a block saver as well, protecting the back of the engine block from transmission failure. F85 442 Cutlass Starfire Delta 88 Delta 98.
