I am refreshing my 383 sbc tpi with 54000 miles on her she has been getting low on power, I dissembled the engine
and the top rings all have the same wear witch seems excessive to me, the rings were ductile iron and the pistons were Hypereutectic,
is this normal. Thanks for opinions. Also 2 of the rings were broken.

Those were Hasting rings that came with the pistons, they were moly ductile iron, 2nd ring and oil ring look fine, fitment was fine when new.
the rings in my failure experience were also Hastings. in my case the engine ran very well for 3k miles. I pulled it out and reringed it at my expenses to make the customer happy. Hastings had no interest in talking about the issue. #NeverHastings
