[Fot] Harmonic Dampener Question... now studs

[Mike Munson]

Bob,
It could be you have broken rings from detonation. 
I ran stock pistons with 14.5/1 with no broken piston ring problems until I
put in a 110 main jet when I should have put in 120. I did get new
(stronger) glasses to solve the jet problem.:-)
