Message: [QUOTE="mtk, post: 1079531, member: 54339"] Very true, Patman. The 2001 & upo 7.3L Power Strokes shouldn't be pushed over about 330hp with the PM rods. The earlier forged rod engines can take substantially more power. With that said, a 7.3L PM rod engine that is chipped to 325hp is still plenty strong (and will get great mileage to boot). It's true the earlier IDI engines weren't as good as the later Power Strokes, but they were still decent engines. As far as being long-lived, my understanding is that both the Cummins and the 7.3L International (the Power Stroke is an International motor with Ford electronics on it) are both rated at 350,000 miles (I don't remember if it was the 50% or 10% rebuild level, but both were rated the same).
