You do hear about people who swear by them but I think a certain percentage of people are just happy, with whatever they have, just for the sake of being happy - the Pollyanna syndrome. If you made me buy one I'd certainly get the earliest one I could find, i.e. a 96 with a 722.3. With a 104 motor you at least know you'll get a long life - top and bottom end. 112/113 motor ring blowby is terrifying to me - I'll never have one.
