I'm curious why you think that, Jerry. I've seen statements from both the
factory, and race engine builders, that they do serve that purpose. That
big metal fan provides the weight (usually found in a solid ring on a
'normal' damper) and the rubber provides the elastomeric element to dampen
ringing. I've also seen the cranks broken by those who race without a
damper.

Another solution of course would be to add a thermostat to sense underhood
temperature and start the fan. Even some 'modern' cars did this, before
fuel injection eliminated the float bowls.
