A good place to start is to make sure you get a 5.9 from a 93-95. 96+ was
OBDII and non-EGR.... really gonna' be a pain to make it work...

>>1. I know that the 5.2L was internally balanced, and the 5.9L was
>>externally balanced.
And to use the 5.9L motor I must deal with that issue. Do i get a balanced
torque
converter?<<

Yes. That should work just fine

>>2. Also I dont know is if motor mounts are a problem. Do they need to be
>>beefed up? Is
an adapter needed? I wouldn't think so. But I'm not sure.<<

same mounts. no biggie

>>3. And I dont know if there are Cal Smog issues with this. So 2
>>questions come up:
a. If I stick with the stock 5.9L PCM, does the PCM need to be from the
same vehicle I
got the engine from? <<

PCM needs to be from the corresponding year and same driveline/trans setup.
a MP pcm for a 4wd auto won't work with a 2wd manual setup.

>>b. If I want to use a M.P. PCM, does the PCM have to match the donor
>>vehicle/engine
combo or the recipient vehicle/engine combo if i want to be "legal"?<<

The MP PCM's have a broad specturm of part numbers. I'm pretty sure the PCM
for 93-95 is the same. you should be okay. I'm pretty sure they make a
California version of the hot pcm

>>4. Can the original cooling system be used or is there a change needed
>>here?<<

should be fine... go with a 180 t-stat, especially if a MP PCM will be
involved.
