=A0=A0=A0=A0=A0=A0I have two Ford pickups. One is an '89 F-250 Lariat
4X4, auto with a new 460 engine.

=A0=A0=A0=A0=A0=A0The other truck is a '90 F-150 Lariat 4X4 auto w/OD,
and a well worn
302. Both are now "work" trucks and are driven every day.

=A0=A0=A0=A0=A0=A0=A0=A0The F-150 still runs well, even with all the
miles on it, and it gets EXCELLENT, (or, at least, I'm satisfied with
it) gas mileage. Unfortunately, the F-250 doesn't.

=A0=A0=A0=A0=A0=A0I didn't realize it when I purchased it last fall,
but, I think it must have been a specially ordered pick up because it
has an extremely low-geared rear end, and NO overdrive.

=A0=A0=A0=A0=A0=A0At 55, you can hear that big 460 whine, like it's
stuck in a lower gear, but, according to several reliable mechanics, it
isn't. The truck was obviously built to work off-road more than on.
Hence, the low gearing.

=A0=A0=A0=A0=A0=A0=A0=A0My 1st question is, does anybody know if I can
get a higher geared rear end for it?

The second, will I have to change the ratio in the front axle as well?
Won't that affect it's 4-WD capabilities if I don't? Thanks in advance!
Joe
