LMP is the Le Mans Program, when chrysler ran in it pretty heavy. They had lots of very cool exotic parts, too bad it had to go away....

The 6 bolt mains also create a problem with oil pan clearance to K frame. Even though you may be running a shallow pan, the pan rail is about 2.5" lower than a stock rail. So you will end up modifying or building your own pan. Or making major changes to your K frame.

The motorplate is really just two plates that bolt on right next to the timing cover with two 3/8 bolts I believe. These can be very easily made however you want them.
