Motor is a Shelby engine balanced by their engine shop. This flywheel and clutch were not on the engine when it was balanced, run and dynoed. The clutch needed quite a bit of balancing according to my local balancing shop. It needed a very small amount on the flywheel. Engine clutch and flywheel supplier all told me they are zero balance and they can bolt together fine. I asked if the parts all needed to be balanced together as an assembly and was told no. After I had the problem the story changed to "we recommend everyone balance their clutch flywheel assemblies".
