Heres some food for thought. Back in mid 94 when Ford come out with the powerstroke 7.3 that was huge. It istantly put Ford on top of the diesel wars and sales. It left GM in the dust as faras power and longevity go. It would take GM 7 years to counteract with something. To the point that they were selling very few of there diesels in the last few years. Dodge had there cummins but Ford really owned the market for that time period. Ford still outsells Dodgeand GM together as far as diesels are concerned. Except for Fords early problems with the 6.o. Fords reputation in diesels has been pretty stellar.
