I can't help remembering that wild cams impose even wilder acceleration loads on the cam-to-follower interface. Add marginal lube on starting an OHC, and an initial pick-up fret is easy...
The peak loads are much worse with rocker followers, and it took GM years to get the J-series in all the 80's Astra and Cavaliers sorted, which ISTR needed a new plasma process inventing to remelt the cam surface.
Did Ford even get the Cortina era pinto right? (nominally attributed to slow oil feed)
These weren't light engines that can be revved hard from cold, either...
