When Chrysler took over AMC they issued an order to all the dealers to
return any AMC parts they had. Those parts were then crushed, no doubt
there was some business reason for it (probably a tax reason), but it
was still a really bad decision.
I don't imagine the order applied to Jeep parts, but if you need a NOS
taillight lens for a 74 Gremlin forget it.

The alternatives are just regular old boring V6's, pretty much minivan
engines, and for a real Jeep they just aren't as good. There were two
big reasons why I bought the Jeep I bought, first it was a small station
wagon, which is a REALLY handy design and what I needed for work at the
time, the second was that wonderful six cylinder engine. When I was
looking at this Jeep there was another one sitting on the lot right next
to it. Virtually the same, same options, same price, just two
differences, the other one was new, and it had the four.
I didn't have to think twice.

I understand WHY DC made the choice they did, I just happen to think it
was a wrong choice (and wrong choices aren't exactly an alien concept to
DC!). You may be right about most Jeep customers, but it's not exactly
a small percentage that DOES care... hmm, a radial, now THAT would be cool!

Re: 4.0L vs. 3.7L
Heck the 3.7 is only having till 2011 run. Then it's days are numbered. I'm
hoping it will go with a head improvement. With the overhead cam engineering
there should be little trouble in adding a extra valve (s). Man I love to
see a quad valve design on the reving engine. The complete lower end would
need no change what so ever, just beef the chain and sprocket to the valve
train.

Re: 4.0L vs. 3.7L
Jeff,
I suspect that this decision has more to do with economy of production, than
any antipathy that might exist towards the inline six or its fans. And
where were you when they eliminated the inline four? ;^)
