 I traded in a '98 E150 with the 4.6L 
V8 engine that had 143,000 miles on 
a '98 E350 Chateau with a V10 and 
53,000 miles.  The 350 drives better 
and the interior is nicer.  The V10 
has great torque and is quieter thant 
the V8.  Gas milage ranges from 11 
City to 16 Highway.  This van is set 
up for towing not good gas milage.  We 
will have to see how the V10 holds up.
