I replaced my V10 at 460,000 miles. It was mostly fine still, even had good crosshatching in the cylinders still. But low fuel pressure cause a spark plug to melt and the electrode lodged in a valve seat. I planned on just having the head pulled for reconditioning, but since book labor included R&R of the engine, plus removing the timing chain and head, and was only a little more for a complete factory motor with a 3-year warranty.
Still have the original transmission too. Not even touched except a total of 3 filter changes. I'm at 470,000 now.
FWIW - over half the miles are towing miles, and typical combined weight was 22,000 and occasionally over 25,000.
That’s very impressive!
