I would stay factory efi, if you just want a cruiser.
You need to be resourceful. A 95 an older AUTO magnum computer will work behind a stick. If you do a magnum swap, the 727 or 904 will at least need a notch in the bellhousing to pick up the crank signal off of the flexplate.
If you want to do some bigger modifications, I would recommend a 96 (obd II) and newer PCM. The newer ones can be flashed to accomodate some cam upgrades etc.
The other thing to think about is a high psi fuel pump. I would recommend for ease/cost the out of tank style. Mopar perf even has one in the catalog.
Just my opinion
