The Strong, Silent Type
The last couple years reading about how the 7.3 was gonna solve the problems of the 6.2 as far as reliability and complexity seems weird as the 6.2 is probably one of the most reliable engines ever made.
I think the reason Ford has gone with a new architecture of engine is that it is a very old architecture and very well proven. It is also simple.
I looked into a hood of an F250 with 7.3. There was a tons of room. It was quite a surprise as the engine is a big V8.
Service will be easy and access will be a none issue.
Also, something tells me that Ford might put a turbo in it someday. It is good to have a volumetrically small engine.
