They droped from 7.3 to 6.0 to meet emissions we all know this.Emissions. The 2011 6.7l is compliant with the new tier of emissions requirements and Ford also decided to severe all ties with Navistar and build their own diesel engine. In about 3-4 years another tier of emissions requirements will have to be met.
But their 6.0 wouldn't handle the abuse we put on them.They thought a 6.4 with 2 turbos would.But it also has problems with the heavy and steady work loads.
The 6.4 can meet the new imission standards, they aren't comming out with a BIGGER desplacment to meet requirments.
A smaller motor will have problems with heat if its being worked hard. it doesnt matter how many coolers you put on it to keep the heat away.
I think they are taking the reigns from nav. cuz they need to get their name back.
the 6.0 and 6.4 have both hurt their image and have helped drive the sale of the dodge cummins. but if you think that they are creating a larger motor to meet imission standard,nope think again a larger motor can handle more heat. and thats what a motor pulling 26,000 lbs creates,heat and alot of it.
