6.4 or 6.0

[6.0PSD777]

A particular 08 6.4 I am looking at has a claimed 20mpg highway(60mph) and 18 freeway(75mph) and about 16 in town.

Maybe with a DPF delete - 7.3 is a great motor but is getting harder to find a low mileage one...

7.3 :O) all the way or a 12v cumns in a ford truck :O) ...... id give the new 6.4 some time to work out the bugs.......

I agree. It looks like that by the time any bugs might be worked out of the 6.4, then along comes the new Ford built 6.7. Hopefully they've done enough testing on it that there won't be too many bugs. Of course, if there are bugs in the new 6.7, maybe they'll just be "gnats" rather than "horseflies".

6.4 all the way! My 05 6.0 was a problem child, Personally my experience with the 6.0 wasn't good. My new 6.4 is 100X better.
