All: Thanks for the information/opinions, this is very helpful. I'll
probably have more questions if/when I actually get around to doing
this.

Thanks again!

My 1999 TJ gets 18mpg without a problem. I have the 2.5L with a 5 speed.

Also have 4" of lift and 33x12.5 BFG MTs. I get up to 60-65 without a
problem. 70mph is doable without a head wind and no hills. I use 5th gear
all the time too.

And yes, my speedo is dead on (replaced gear, verified with GPS). I've done
a few engine mods, but nothing serious: Cold air intake, throttle body from
a 4.0L, and dynomax cat-back exhaust. But the most important mod was the TB
spacer! YA! (heheheh...)

Putting around town is a lot of fun in an old Jeep. I have a lot of fond
memories of doing that. Lots of attention and it's just plain cool.

However - Old Army Jeep on the freeway? I personally wouldn't - that's
why I'm building "Frankenwillys". There are plenty of old Jeeps and
****** that are a lot better at speed than military style Jeeps designed
for pulling cannons across muddy fields.

Despite others driving fast with newer engines in various flavors of
Jeeps, the original Jeeps are really narrow and there are a lot of them
gone from this world because of it. Drive 70 mph in an MB in a wind and
hit even a small pothole and you could find yourself flipping like a
Chinese acrobat.

With the amount of mods you have to make just to make it a modern
driver, there might not be much Jeep left. Not that you can't do it (I
am with my Frankenwillys), just be aware that it's a VERY complicated
and expensive undertaking. I'm not doing it to save money, I'm doing it
because I REALLY want a ****** Wagon 4x4 that I can drive at 75 mph all
day long. http://www.jeffgross.com/******/

You might be better off just buying one already converted by someone else.

Cheers,
- Jeff G

p.s., before I get a bunch of emails about why I haven't updated the
website :: I will be soon, just finishing a couple other projects that
are a higher priority ("OK honey ... Yes dear ...") The ****** is coming
along pretty well, I'll get more pictures up soon - I promise! ;)

As you aren't that concerned with keeping it stock one thing you might
consider is a swap that I've heard was popular years ago, replacing the
little 4 cylinder with a Studebaker Champion 6. They aren't all that
big, their tough, believe it or not there is a fair amount of hop up
stuff available for them, and apparently they had the same bolt pattern
so they will pretty much bolt right in (which is why they were a common
swap in the old days).

Just found this interesting article...

Just a thought...

Oh, and whatever you do put some modern tires on it!
