Accordingly, why did they stop making the 7.3 Powerstroke?

Registered. While Ford dropped the 7.3L PowerStroke in 2004, I believe Navistar continued to produce the 7.3L ("T444e") for use in their medium-duty trucks through 2005 (possibly into 2006). Ford dropped the 6.0 because of reliablity issues as well as emissions mandates. Navistar continues to produce the VT365.

Secondly, is the 7.3 Powerstroke coming back? Some think that Ford took a step back when they announced its new gasoline-powered, big pushrod 7.3-liter V8 motor that will soon power the new 2020 F-Series Super Duty trucks. The answer is fuel efficiency. Production-wise, the only pushrod V8 that Ford still offers is the 6.7-liter Power Stroke diesel motor.
