we must have at least a couple of hundred Z owners here with UD pulleys. Lets do a poll and find out. should be able to get some basic stats from available data of Forum members that would apply. The point still is that Z32's do not have Harmonic Dampeners..they dont need harmonic dampeners for reasons already stated in other post. Torsional dampening yes, not harmonic. So, Poll should be...how many spun bearings at what mileage and ltwt pulley or not, rebuilt shortblock or factory. I'll be suprised to see 1%...and then we can argue about what percentage is actually statistically significant. If it were truly a problem inherent to the design of the Z engine and using the pulley then we should expect to see a large number of users of having spun bearings ect.
