I had a 2000 f250 with the 7.3 and then a 2002 f350 with the 7.3 and never had a lick of trouble with either one of them, bullet proof, dependable, great on fuel, ton's of power and then Ford went to the 6.0 and nothing but problems, then the 6.4 and what a pig they are. Eat fuel like no tomorrow....
