Infamous? I think you have confused the 7.3L with another engine. The 7.3 PSD is still in great demand because of its reliability and performance. The 6.0 and 6.4 had some issues, and do not have a great reputation.
The 7.3 isn't in demand because it is such a great engine, its average at best. The ones after it were so troublesome that a legend was built around the 7.3. Its power was average, and it leaks oil about like a Land Rover when it gets some age.
