A Mid motor plate, made of steel or aluminum, is useful for custom cars, racing or engine swaps, and they make it easier to mount any engine into any vehicle. A mid plate used with one of our front motor plates provides the ultimate in flexibility when doing an engine swap or custom installation.
Mid motor plates are available in both 13 gauge mild steel and also 6061-T6 aluminum. These mounting plates are very popular for all types of drag race vehicles, door cars, dragsters and roadsters. These mid engine plates also provide an easy way to mount a different engine than what may have come in the car or truck you are working on. You can also swap in a different brand of engine. These plates also work well for street rods, "Pro-Street" type vehicles.

A mid engine mounting plate installs between the back of the engine block and the transmission bellhousing. The outer edges of the mid motor plate are then attached to the frame rails, usually by being bolted to "L" tabs that are welded onto the frame rails. The mild steel mid plate is thin enough that it does not generally require any changes on the torque converter. The thicker aluminum mid mount plates require that spacers or washers be used where the flexplate mounts to the converter or the tabs on the converter can be made thicker by most converter manufacturers. If you plan on using a mid plate, let your converter supplier know and they can make any changes required. In some cases the center of the converter hub needs to be extended to insure that it still centers in the back of the crankshaft properly. Any excess material on the mid plate that you do not need can be trimmed off.
