They also powered the F650/750 until a couple years ago with an Allison 3000 behind it. Lots of Freightliner MD's.
Why would Ford switch from an almighty Cummins to a light duty engine to power their F650/750 trucks......unbelievable:?
I think FISH got tired of me pointing that out and got someone at Ford to make the change!
The reason for the change is:
6.7 Cummins B10 rating is 250k miles
6.7 Power Stroke B10 rating is >500k miles. Also the Power Stroke has a 5 year 250k mile powertrain warranty.
I know which engine I want in my medium duty application. :B
And the commercial industry is loving the new Ford medium duty trucks since they can simple take their truck to any Ford dealer and have the truck serviced or repaired and from I'm hearing the new factory is backlogged into the unforeseeable future. Hence the reason GM is jumping back into the medium duty truck industry.
As usual Fish does not fill in ALL the blanks.
