6.4 vs 6.7?

[ezzrider]

Congratulations to everyone that has purchased the new 6.7. From what I read the 6.7 is a great engine and I am hopefull the fuel economy is better than the 6.4. I own an 08 6.4 and was wondering if anyone had previously owned a 6.4 that purchased a 6.7 and had input as to differences, improvements and if it is worth switching from the 6.4 to the 6.7. I purchased my 6.4 when they first came out and I see all the same excitement in this 6.7 forum concerning delivery dates, build dates, etc. I understand that Ford in the near future will be actually building there own diesel engine again and not contracting out. Will the 6.7 then go by the wayside as the 6.4?

As a Ford truck salesman, they both have their positives--the 6.4L does have great immediate power and response, and a good level of quiet (if you want quiet). However, the 6.7L (I have driven a Crew F-350 that I sold to a customer) has more power, is quieter, even faster response, SIGNIFIGANTLY BETTER GAS MILEAGE, and you don't have to remove the entire cab to access the engine for any major engine/trans service, or remove the DPF to increase your MPG. I do enjoy driving the 6.4, but I will say that the 6.7L is better overall.

Thanks for your input.

Right on. If you can, go with the 6.7L--just remember to buy a 5 gallon jug of Urea so you can fill up when you need to at oil change time.

also the 6.7 is ford built. not a navistar/ international

[FX4 Fiend]

Which is huge--there is no confusion regarding Navistar's engine and Ford's wiring and computers. Also, Ford TESTED this engine in real world conditions, unlike the 6.0 that they threw out to meet CAFE standards. This engine is for real, people.

Go for it. Keep in mind, one if you're going for a longbed, you can get a 5th wheel prep pkg. If you go for the chassis cab for a towing rig, however, the 6.7L has a more traditional turbo geared for heavier-duty commercial usage.

it will be the same set up as my current truck. 4 doors with a short bed.

Then go for it. 6.0 (as long as the kinks are worked out--and I guess they are) was/is a great engine--but the 6.7L is fan freaking tastic. The one that I delivered came from an 08 6.4L Lease--he was skeptical, but when he drove it, he couldn't sign the papers fast enough.
