Ford 6.4 or 6.7?

I can only state that I have HEARD the 6.4 does not give the best mpg.

The 6.7 is a Ford in-house developed engine. The 6.4, like the preceding Ford diesels was developed by International. That's not a bad thing at all, but I think Ford got so much bad press because of the 6.0 that they decided to develop their own diesel engine - thus the scorpion 6.7 came into being.

I have a 2013 F350 6.7 and it is simply terrific. I never want to get out of the truck. It gets very good mpg and is super strong.

The 6.7 IS that much better. I cannot advise you about the pricing, but there is no question in my mind that I would want the 6.7.

* Ford does have an after-market warranty available for various periods of time. Maybe try and work a deal that includes some extra warranty time.

All things considered equal I'd go with the 6.7.

I have no experience with the 6.4. I do have a 2012 6.7.
I would go with the 6.7. Great power. Reasonable fuel mileage. Only real complaint I have read about the 6.4 is poor fuel mileage.

Both trucks were bought and sold back to the original ford dealer where bought new. They both have all service records.

Without a question get the 2012 Cummins! :B

Really I would go for the 2012 6.7! See if you can get a car fax, and service records. The 6.7 is FAR better than the 6.4.
