Never heard of Performance Powertrain?
Are you talking about American Powertrain's stuff? If so then that's great because its the same stuff I use on my T56 Magnum. I run their hydraulic setup along with their Science Friction Street Slayer clutch and no problems whatsoever. Have been running it for about 4 years now. I actually have a spare Science Friction Street Slayer clutch disk when I swapped from 340 to Gen3.
