Yep, my wife's 04 WJ was the last year for the I-6 too and she bought it
becaues of the I-6, Tried and True.

Re: 2007 Wrangler???
I don't have a link but I do have a copy of the 4.0L I-6 torque curve
and it shows 210 ft-lbs. at just 1200 RPMs all the way up to nearly
5,000 RPMs. It's pretty flat between 1200 RPMs to just under 5000 RPMs
and it's all above 210 ft-lbs at all RPMs between them.
If you look at that 3.8 chart, you'll see what I mean about the V6 not
developing that kind of torque until around 2300 or so RPMs and it's a
very "peaky" curve, not even close to the relative flat torque curve of
the 4.0L. Below that RPM, the V6's chart shows the torque takes a
nose-dive. This is why the 4.0L is such a superb engine for offroading,
it's flat torque curve that starts at just above idle RPM. Too bad the
government made it difficult enough that Jeep had to drop the ideal
offroading engine in favor of one with less than ideal torque
characteristics that are way less suitable for offroading.
What I don't understand is how GM could develop a new inline-six that
has good low-end torque and Jeep can't. I could probabl learn to live
with that new V6 if I were to buy a new 2007 (which I have no plans to
buy) but I wouldn't like it. :)

Re: 2007 Wrangler???
A change in camshafts can DRASTICALLY change the torque curve of ANY
engine.
