Dodge is Dodge...
Ford is Ford...
Cummins is Cummins
Navistar is Navistar...
Anyone doing serious reading of the history of the auto business will soon realize ther great amount of overlap that exists between car makers - they share executives, suppliers, and undoubtedly, some major component manufacturing facilities.
As in the Dana differentials used by both Ford and Dodge.
That in NO WAY means that a Ford is REALLY a Dodge - or vice versa...
Individual technologies, designs and basic material standards exist to assure EACH maker's final product is individual in quality and engineering. Fact is, if MANY of the individual components of a Ford and Dodge truck were laid side by side, you would probably find MANY, that while different in shape or function, came from the SAME manufacturing facility in some USA or latin or Asian country of origin.
So if some foundry is found to be casting bare blocks or heads for any/all of the "big 3", does that mean they're all the same in design and quality? NOT by a LONG shot!
The Cummins will be cast of the iron composition and design specified by Cummins - as will Navistar's stuff - it makes good sense (in ocassions where it actually DOES happen) to COMBINE various manufacturing operations as a cost control measure - hopefully, lower end cost and price to the consumer will be the result - and it most certainly does NOT mean MY Dodge is the "same as" a Ford!
