" From: Jim Blair <carnuck@xxxxxxxxxxx>

" 
" The GM 2.8 flexplate is different from the Jeep 2.8 flexplate
" (different transmissions)
 
i know; i was thinking of zero-balanced 2.8s [or 3.4s] with manual
trannies.
 
A: The GM flywheel is a different offset than the Jeep one.

" Mopar used hydraulic 4 speed autos '88 to '92 then electronic '93 up
" (only the valve body controller)
 
...and that's also when the 3.9 went to mpi?
 
A: Most likely. I know they had a pitiful TBI at first (so did the 5.2L Dodges)


another q: i know that 4wd 904s and 727s are the same length, but i've
been assuming the 4sp [a500, a518, etc] are longer.  t or f?
 
A: True. I measured them a long time ago so I can't quite recall, but the AW4 was 3.5" longer than 9XX or 727 4x4 versions and the O/D of the Dodge trans was (poorly) grafted onto the back of the case (which tens to snap out when shifting to O/D under extreme loads, like hill climbing while hauling a trailer)

"    The 2.8 in my '86 MJ project (actually, my room mate's MJ now) was
" 5 speed. AX-5 with either NP207 or NP231.
 
is that one of the late, zero-balance 2.8s?
 
A: Sadly, we don't know. The original motor was gone when we got the truck and a FWD version was sitting in the back (they gave up trying to put it in) The flywheel had a chunk out of the center (I think the OEM motor tossed a rod at high speed and the truck screeched to a halt as the tires have a flat spot like being dragged) and I tossed it in the scrap after comparing it to the FWD version.
   I was originally going to take the 2.8 from the '88 Chev Celebrity wagon my son had, but I gave that to the Seattle Fire Dept to practice rescues on.
