In superduty trucks, the 7.3 powerstroke was available 99-mid 03, replaced mid 03 with the 6.oh crap, what broke now.
The 7.3 powerstroke came in the previous generation body style starting in 1994, replacing the old 7.3 diesel/ turbo diesel mid year. Same displacement figure of 7.3, but entirely different engine.
There were some longer overlaps/ availability in commercial vehicles and special comfigurations. What I listed above is referring to f series trucks bought by individuals.
