Could the distributor be work enough to move the rotor too far away from the non firing plugs?

By chance did you put the wrong flywheel on? A 91-97 flywheel on a 87-90 renix will cause the exact symtoms you have.(Been there. Done that)

Yes came off of my 89 renix block I used not to mention it wasn't doing any of this when I spun the bearing the only problem I had be for was it would cut off while I was driving sometimes so I replaced the harness and that problem went away

I just saw this and it's old but I bought a jeep that wouldn't start after motor swap. It was only firing on 2 cyl and it ended up being a renix flywheel on a HO motor.. The PO swapped a renix block in and didn't change the flywheel. It had me scratching my head for some time....LOL
