<VV> Cracked Pistons

[James Cuneo]

Bob thanks for responding, I used your book in conjunction with the shop manual when first building this engine. Initially I could not be more happy with how engine performed even with the stock carb.As for the damper, I purchased a rebuilt unit from one of the popular vendors at the time in '07. I don't remember which. When I degree'd the cam I found the timing mark off by 1/2 degree and made a new mark. I will check tonight to see if it has slipped.Jim

Jim,
A WAG long shot. But what kind of harmonic damper are you 
using?
Regards,

Guys,I 
  need some help from you engine gurus out there.I have cracked 3 pistons in the 
  #5 cylinder in the past four years. 2nd time I thought it was a coincidence 
  that it was the same cylinder, third time, now I wonder what is happening in 
  #5 that sets it apart from the 
others
