The rings are too thin for the piston groove.
Piston Ring Wear: is this Normal?
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.

Mic the ring and you'll find it tapered. It's been smashed flat, because it rocked in the bore.
It rocked in the more from either the bore on the big side, and/or the piston lands are too big.
The smearing of the face is your biggest clue.
