What is the best year of 7.3L Powerstroke? Specifically between the years 1990-1997? I like the old classic bodystyle of those years.

 

1997 was the best best. Most of them by now have had a few injectors and O-rings replaced on the rest. If you have to have an automatic, the E4OD or 4R100 (just about the same beast) that's been reworked will do well. If you kept up on maintance with these, as well as anyhing, it really pays off. Good luck!
