No, it's basically identical to a total rebuild, with a little extra
minor machining. There are excellent write ups, including build up
recipes for various budgets from lowest budget 4.5L (no .30 overbore and
using all stock and junk yard parts), to high compression custom piston,
custom ground stroker crank 5.0L. putting out 300HP normally aspirated.

Nothing special is needed in terms of fuel injection knowledge, there
are a few things that can be done to resolve pinging if it runs too lean
(and it probably will if you use stock size injectors) but these are
none to complicated and there are write ups of them as well. (adjustable
fuel pressure regulator made by He$co, larger Mustang injectors,
adjustable throttle position sensor using 3 dollars worth of radio shack
bits; are three of the potential solutions. Besides having the factory
ECU chipped and dyno programmed which is the best highest performance
solution).

These are good starting points:
http://www.jeep4.0performance.4mg.com/stroker.html
http://www.angelfire.com/my/fan/stroker.html

The Yahoo strokers group is a good place to ask specific questions and
get help, the latest topics here are a few guys working on prototyping a
roller valve train(!)

and the forums at naxja.com are filled with Cherokee owners quite a few
who have stroked 4.0's (very popular mod with XJ owners)

Corporate Torque Flight 999 3 speed in the YJ's AND TJ's until they got
the 4 speed 42RLE in the later TJ's.

Can't find any mention of the AW4 ever living in a YJ or TJ, if you can
find something please post a link or any info you find. I would
absolutely love to pull a transmission cross member, transfer case and
drive shafts out of a salvage AW4 equipped YJ or TJ.

Maybe you're thinking of the AX5 manual they put behind the four banger?
I'd love to be proven wrong here it would save me from custom drive
shafts and time fabbing my own cross member.

Re: 87 YJ
 

I've been doing some extensive classified searches and it seems like
I'd be kind of dumb to pass this up - I can't find anything else within
200 miles that's below 3k.
Are there better Jeep-specific classifieds where I'd have a decent
chance of finding part-cars? I've been over to 4x4wire, not much
there.
I think a junkyard trip is in order for tomorrow morning.

Re: 87 YJ
 

I am pretty sure that the owner's manual for my 95 YJ says "3 speed
automatic". Yep, I just looked. "PRND2L" is what it's got, in automatic
configuration. I don't think that there is any "Donner" four speed that
will fit. Still, you could do a lot worse than a hydraulic Chrysler auto.
