Question Any fuel milage reports on the 3.55's
I haven't seen any fuel milage reports for the 6.4L with the 3.55 rear-end. Post them if you have any... -g

I'd be interested to hear this too. However, I can't see it being much better than the 3.73s, and 3.55s are thin on the ground at dealers.

Thanks for the feedback, that's great, is it by the lie-meter or hand calculated? -g

15-16 for a whole tank. It's mixed hwy and city. It gets well below that in the city.

How many miles on this truck?. Sounds like pretty good MPG. I could live with that.

Not if you're looking at F350 SRWs, at least up in Norcal -- someone figured out that folks might just want some mpg's...
