I'm at 415k miles. made it pretty far. I doubt the previous owner did much to it. hope I get her to double that milage. my IDI is going towards 330k. needs injectors soon and I rebuilt the transfer case. can't beat them 7.3s. only mod I have on the powerstroke is a cold air induction my IDI is bone stock.when I was looking to buy, I purposely ruled out every engine, except for the 7.3L which has a Long History of making 250k to 350k miles w/o major problems IF left STOCK
