Need  help figuring out the most reliable harmonic balancer 140 motor-Clarks
vs.  Dale manufacturing? Any advice will be helpful.



John,
I doubt that you will get any definitive explanations or data. So all you  
probably will have to go on is some possible logic to consider.
 
Dale is rebuilding the original factory units and tuning them to the stated  
factory frequency. (they ARE tuned, you know!!) He has done over 5000 of these 
 and has an excellent record. Besides he provides a lifetime warranty. How 
can  you go wrong?
 
Clark's is selling units that are either made by or for racer Bob  Coffin (as 
I understand it). These are new units. But are they built and tuned  to the 
Chev factory specs? Or are they built to a better spec? And what might  that 
spec be? This might require some investigation to determine. If they are,  then 
it's probably just a matter of cost and availability.
 
In my opinion, the factory damper was really inadequate for racing and one  
should consider adapting a viscous-type damper.
Regards,
Bob Helt
