Anyone know if I can use automotive rings on my 4.3 LX Gen+

[jimmbo]

seems like they made them with metric rings at some point. wonder why

Maybe made in a Plant outside of the US

GM has been making cars, in North America, with a mix of SAE and Metric parts since the 1977 model year

I know the finish grinder for the rings was set to .058" according to Dad regardless of spec in inches or mm (retired from the Federal Mogul plant in 2009)

Rings were done in Sparta Michigan or Manitowoc Wisconsin for GM (including rings for JDM cars, Ford, CAT, Cummins, DDEC, Komatsu etc. )
