I've swapped the motor out of my 95 4x4 Jimmy to the 95 2wd Jimmy everything went smoothly except for one of the fuel lines, but I finally got that in straight. Once I got the distributor back in and fired it up I heard a grinding down at the torque converter. I was not so concerned with this until I got the timing set correctly. After timing was set I was able to go under and inspect the noise. It looks like the flexplate is making contact with the bell housing @ the 10 & 2 bolt eyes. The noise is not constant. It goes quiet after idling for a while. The noise is there under acceleration but it does not sound serious. I had no noise in the old bell housing but I just went and looked at the old transmission and the inside is marked up as this one is getting. Cracked plate? Two piece housing is great.
