Update. I've been going over everything, checking, measuring, cleaning.. It's going back together now and I have found nothing that would explain what was going on as far as fit or clearance. All the bearings are good, end play is where it's supposed to be on the crank and rods. Lash on the timing gear is correct. I had one cylinder that was not firing as the others were (as evidenced by the lack of soot on the exhaust valve or piston top) so I'm going with one dead cylinder (plug wire) and timing as the likely culprits. It'll be a few days before I have it closed up and back on the run stand. (I've got a few real life things that keep popping up) I'll post the results, good or bad when it happens.
