this may be confusing but anyways im looking into buying a 90 mustang GT 5.0 the motor was completely rebuilt less than 500 miles ago, the problem is he says that he put the wrong crankshaft in (Eagle #356-103023000) and its too heavy or something and he was supposed to use (Eagle #356-10302300-50) the motor vibrates at 3k rpm or higher he claims as well as other people that if you replace the flywheel with this flywheel from ebay (item # 220400907058) that it would fix the problem is this complete bs or as simple as that.
