Did Ford build the 7. 3L? Navistar built the 6. 0 to the tune of $500M in warranty costs and the 6. 4. If Ford puts a Scorpion in an F-350 it does so remembering the 6. 0 fiasco. My bet is on Ford to have a good product and put Dodge to the test. Cummins will respond.
Navistar International did produce the 7. 3 powerjoke as well as the engine before that, I believe it was a 6. 9, without a turbo. That was a worthless gutless engine.
I don't share your confidence that furd can produce a good diesel engine. If they could, they should have done it years ago.
