BradB, I'm surprised to learn that the Jeep 258 had 7 main bearings, because I knew a kid in high school that drove an early wrangler with that motor, and the mains were so loud it sounded like a diesel. Unless it was the rod bearings. Either way, the low-end was pretty smacked up.
Over-rev them in 4 low a few times and you can do that to them. I've seen very healthy engines of several designs fail to survive a driver who was not smart enough to realize that.
