This is the second time I have encountered this issue. The other time was with a 352 Fe in a '59 thunderbird.



The original rings I removed from my piston are as follows:



1. Top compression ring has a bevel on the upper inside edge

2. 2nd compression ring has a dot on top and a bevel on the lower inside edge



This is consistent with all 8 pistons.



The Sealed Power cast iron ring set differs from the originals; the top ring is the same, but the 2nd compression ring has a dot on top and a bevel on the UPPER inside edge--same as the top ring.



With my '59 T-bird, I went so far as to contact the manufacturer, and they said to go with the dots (install them toward top of piston, regardless of bevels). When I put the engine together, it ran fine, but blow-by was excessive and compression was about 20 PSI lower than it should have been with fresh rings. I do not want a repeat of that scenario if I can help it.



Has anyone else noticed this about the sealed power rings? How should they be installed?
