Mine seem to go 100,000 or more, no problem. I suspect it depends greatly
on the quality of oil used, and how often it's changed.

ISTR it was the Haynes manual that actually recommended changing the rod
bearings every 30K or so. You can do the mains too, if you're so inclined,
all in an afternoon. However, the timing tensioner is a lot more work, if
you still have the fan and extension. With them out of the way, it's only a
moderate PITA, but I'd still rather change the rod bearings.

Yes, but it's been long out of print. I'd love to scan it, if anyone has a
copy they would be willing to loan/rent/sell to me.

They had to leave something for the likes of Kas Kastner to do!
In addition to somewhat rougher idle, the car becomes harder to launch and
requires more clutch slip. Probably shortens the life of the clutch, too.
