Discounted blocks.
2008 6.7, all nearly perfect bores except #6, which lost the top compression ring when nearly new, so now it needs a sleeve, .020" WON'T clean #6 up, $550.
2011 6.7 block, very mild rust in a couple bores, light gouge from a dropped valve in #4 cylinder, this block MIGHT clean all bores up at .020, but no guarantees, $600.
2015 6.7 block, notable rust in 3 cylinders, IMO this is a deckplate candidate, as I'm not certain .020 would even come close to cleaning it, $500.
All 3 of these currently have nice cranks in them and I would sell them as shortblocks, minus oil pans, for $1200 each.
Mark.
