I just installed my new motor and transmission and it's running great except for a horrible vibration coming from the drivetrain. It vibrates at an idle then gets worse and worse as rpms increase. I took the car to a shop to get dyno tuned and the technician told me the flywheel might be the cause. For now the car is garaged untill I solve this problem. Anyone have any ideas? Do flywheels have a certain way to be installed? My setup is a Ram Billet Steel Flywheel, Centerforce Dual Friction Clutch, Ford Motorsports Throwout bearing, and Tremec TKO 600 all brand new parts. I also have a Ford Aluminum Driveshaft that I've had for a while, never had a vibration problem.
