i know you hate being wrong ego but here is more info since you dont seem to want to believe us.
quote:Many engines, including virtually all V8’s, V6’s and inline 6’s, use a device on the free end of the crankshaft to attenuate the amplitude of what could otherwise become destructive torsional oscillations of the crank. Without an appropriate absorber, the life expectancy of the crankshaft in a typical American V8 engine at full power can usually be measured in minutes. (The flywheel-less Sprint Car V8 engines with the water pump attached to the nose of the crankshaft are indeed a special case by virtue of the substantial alteration in natural frequencies by the lack of a flywheel, coupled with the natural damping effect of a water pump.).
