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.

Centerforce uses Valeo pressure plates. Usually they will just paint them orange though but my centerforce has a valeo pressure plate as well.

Thanks for the help, I am trying not to rebuild the entire car at this point. I will probably use this combo if flywheel checks out.

Could also be a rebalanced 82-85 5.0 FW. Personally I'd use a clutch with a minimum 10.5" diameter
