<VV> Cracked Pistons

[BobHelt at aol.com]

Hi Jim,
Thanks for the reply. I was more wondering if MAYBE, somehow  the 
possibility of insufficient harmonic dampening MIGHT have some relation to  your 
pistons cracking. #5 piston is down there near where most crank failures  occur. 
Just a long shot.
While I'm wondering, at what engine speed did these failures  occur?
Regards,
Bob Helt

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.
