I pulled the motor and manual trans out of a project car, 87 Mustang, 351w, Tremec 3550. The clutch is a 10" Centerforce, pressure plate is a Valeo, flywheel is a Ford, 157 teeth, with numbers E1ZR6380-A2A, E6ZR-AA. This appears to be a mis-matched combo. Clutch is in excellent condition, flywheel and pressure plate have signs of wear. Any comments or opinions on reliablity. Vehicle will be drag only, 400 to 500 hp, all motor. I can not find origin of flywheel, believed to be from a truck.
