Great motors. Tried and true with millions of miles on them. Ford should have kept it considering the 6.0 gave many people problems, but keeping the 7.3 up to date with our BS emissions proved troublesome and expensive.

7.3 L Power Stroke Facts
The 7.3 Liter Power Stroke is similar to the International T444E. The T444E is essentially the same engine as the 7.3 Power Stroke, but the "Power Stroke" name is only designated when the engine is used in Ford trucks. Power output and maximum RPM are the only significant differences between the engines. T444E stands for: Turbocharged 444 cubic inch Electronic (as in electronically controlled).
The T444E has been made available in applications above 60,000 lb. GVWR, and extremely popular in the medium duty truck market while it was available.
The 7.3 Liter Power Stroke was ranked in Diesel Power Magazine's top 10 diesel engines ever produced. Over 2 million 7.3 liter Power Strokes are still in operation today.
Over 2 million 7.3 liter Power Stroke equipped Ford trucks are in operation. That's more than Chevrolet, GMC, and Dodge diesel equipped trucks combined.
Though considered outdated when compared to today's diesel technology, the 7.3 was considered to be the leader in diesel technology during the time it was produced.

Diesel engines along with the carbureted 2 stroke engines are the most polluting motors on the planet. They had to be cleaned up. Common rail fuel injection and DPF/EGR sytems were the quickest way to do that. Compared to the Isuzu(Duramax) and Cummins engines, the 7.3 was deemed to expensive to update. The big rig motors got the same treatment.

And let's not even talk about container ships and the bunker oil they burn as fuel. Nasty.
