it was not terribly hard to get 30mpg+ imperial with a 6.2 in a truck, 
no turbo and a slushbox.  They should never have a turbo in my opinion- 
too hard on the center main, unless you do an eco-diesel version to just 
improve VE without increasing fueling.

The 6.5 gets 25 tops, with a turbo.- Mine is a 92 with a crate GM hummer 
block, and Banks turbo and exhaust.

Dad's 04 max got 22-3 before I futzed with it, 28 after, almost 
independant of load, with 360hp at your fingertips.  Futzing includes 
an edge module and juice box. Not terribly imaginitive, but the module 
and controller do the hard work for you.

If you are going for around a hundred horsepower with a SUPER reliable 
motor, use a 6.2 with a 5 speed.  They won't die.  I personally would go 
with an added turbo, but no increase in fuel EVER.  (have lost a center 
main to cracking)

Fords are shit for passenger service.  They are a heavy duty diesel, 
made to pull their ass off all day. NOBODY around here gets much over 
20mpg regardless of what they do to them, but they do handle a load well.
Ford has some beautiful industrial diesel motors, too bad the trucks 
don't get one of them.

A cummins in a doge truck seems to be a happy medium between the two, 
except they are very long, heavy.  A bit more noisy too.
