<VV> FC Engines - Harmonic Balancer or not? No tires.

[EVERETT WILSON]

My 64 Greenbrier has what I presume to be it's original 110 HP engine, Code WB.  My question, since Im slowly assembling parts to install a/c is whether the 110 FC engines were supposed to have the Harmonic Balancer or not.  It didnt have one when I got it, but we all know that things just might get changed over the years.  
   
  The main issue is: I have an early type a/c pulley that is cast as part of the crank pulley.  I had never seen one of these before.  I plan to use it if the potential for engine damage is unlikely.  Im thinking that the revs never get into that high performance vibration creating area that a 110 in a car might.  
   
  Oh, and as long as Im asking....is the cam on the FC different than the car engine of similar year/output?  Would that make a difference in the above question?  
   
  I have changed the heads over to a set of rebuilt smog heads I had lying around and it runs really well and except for this week when the temperature has been 100 plus, is perfectly happy on 87 unleaded.  I was getting some occasional ping and dieseling, so I put some 93 in it this week. That solved both. (Bottom shrouds are still on and t-stats functioning, synthetic oil)  I suspect that if I had gotten around to shroud removal, it wouldnt be an issue.   
   
  So, there are some Corvair questions for the list to mull over!
   
  Stay Cool everyone!!!
