Review on the new 7.3 Ford V*

Regarding the mileage difference between a C and a B+, I can only offer anecdotal evidence. Our Sunseeker gets 9 1/2 to 10, where my nephews Chevy pickup with the same engine, a 6.0L, always got 12. And that's just a pickup.
As far as the Ford engines, it's probably a lot of the same story. The V10 is a gas guzzler, no matter what, and I wouldn't expect much different out of the new Ford V-8.
But oh the power difference…
