I concur. If it continued to run smoothly, it is unlikely to be a stuck lifter/valve. My bet would be on a bearing. Probably spun or simply worn out. You were right to be cautious and have it towed. I have seen a 40 that was running perfectly and within about 5 miles threw a rod through the side of the block. It's relatively cheap to check the bearings and not so cheap to repair/replace the block.
