I had 325,000 miles on my old 88". The records (which were complete) showed valve job, multiple seal jobs, gaskets, etc., but the pistons, main bearings, etc., appeared to be all original, and it ran great. Of course that was a completely different motor. This depends on the quality of the machining of the various engine parts in the V8, and quality of engineering of the same, as well as quality of bearings, etc. Unknown to me.
