Aluminum Front Motor Plate Installation Suggestions:

These aluminum motorplates install between the engine block and water pump. They then go across the engine compartment from frame rail to frame rail. To install them you mount the plate on your engine and set the engine down into the position you want it in. You then install an angle bracket or piece of "L" shaped metal on the right and left side frame rails in position against the motor plate. Now you weld the bracket to the frame rail. Then you drill one or two holes through the brackets and into the motor plate. Bolts are then inserted through the bracket and engine plate, put on a washer and nut, tighten the hardware and the installation is completed. Once you have the brackets in place and the holes drilled, it is now a simple matter to install or remove the engine by just removing the mounting bolts. (Hardware is not included with the plates as every application is different) Any excess material on the plate that you do not need can be trimmed off, or cut into various shapes to compliment your engine compartment. Many people also use the plate as a place to mount various other items, like the ignition coil, radiator overflow tank, etc.

Key Benefits of using a Mid Plate

• A Mid Engine plate eases the installation and removal of vehicles engine and, or, transmission.
• Mid Motor plates eliminate torque roll of engine and transmission within frame as experienced with stock type mounts.
• Mid plates open up a wide number of choices of engine types that can be installed in your vehicle.

Mid Plate Installation Suggestions

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.
