1971 340 Build - Choosing piston rings dilemma

Dont overthink this... Plasma is the process used to spray the moly on the ring... All the same.

Any high quality ring will work. I have used simple cast rings when the budget was tight even on modern engines. Years ago we only had chrome or cast. Top fuel cars ran cast back then...went 250 mph!

Yeah true, wise people have to cut through the advertising jargon B.S. and see things for what they are. That's why I was asking the questions. In the case of rings I don't think the simple rule of "you get what you pay for" totally applies here. You could pay literally twice as much for a set of rings from an expensive brand (eg JP Pistons or Manley) than someone else and not get any difference at all in performance or engine longevity. However if Summit Racing brand rings are made in China, then I would draw a line there and not use them, since the metal composition is pretty important in such a high stress component.
