The plates I spoke of are the stock OEM Chrysler plates. Both Borg Warner and Raybestos make heavier duty plates. If you want a real firm almost rough shift, use the waffle lined plates in both clutch packs. You can also use a red plate from Alto that is used in racing applications. Raybestos also makes a high performance blue plate. Both plates are smooth, although I have seen the blue plates with the lines pressed into them. Your friction material is the most important part of you friction plate, not necessarily whether it has a smooth surface or one that is lined. My boss'es race car puts out about 1200 Dyno'd horsepower, and he runs it to a two speed race powerglide. The frictions used in that transmission are a smooth finished plate, and he gets typically 1 race season on a set of clutches.
By the way Dave, B&M do not manufacture any friction plates. Every kit I've looked at, the plates are either manufactured by Borg Warner or Raybestos, even if they are bagged and the bag is marked B&M. Private labelling is very common if you are a big enough buyer of a product. We manfacture an aluminum direct drum for the HEMI and now the 904 for the racing boys, and have put the logo and name of a noted Chrysler performance aftermarket parts distributor on them.
