Was this a factory roller lifter or a Crower lifter? I had two Crower solid lift cams, one swiped half the lobes and made me get a Uhaul truck and flatbed to get it the last 300miles home, replacement instantly showed signs of scraping after cam break-in. Crower is about ten miles south of me, I won't buy their cams again, but I have had good luck with them re-grinding stock cams in the past. Sorry to hear about the lifter, but sounds like you have been having fun in the meantime.

Considering 135K miles, which is quite a few for such a new engine, that's a lot of driving. Needless to say, was it pitting of the cam lobe itself that ate the lifter or are you able to tell how the failure actually happened? I had a 3.9 with all the lobes pitted at 150K and the roller lifters showed no damage, so your failure was definitely a rare occurance.
