Oh, you mean that "
extensive engine damage" thing?
Five years ago when I was spec'ing out my engine we were still having exactly the same discussion on solid rollers for an FE. There had been a couple examples of the rollers coming apart, and a couple examples of the distributor gear eat-up. I went with the old SFT set up because (once you break it in) it will outlast you and you don't have to do anything with them except lash them every year or so. I had thought the two solid roller issues had kind of gone away, but I think the truth of the matter is there just hasn't been enough time to really be sure.
