Quote: Higher presure cap does not raise water temp. It raises boiling point. Yes new cars do run hotter but lets not forget the new motors are built to much better tolerences. New cars run 200,000 miles all the time. The 60's motors were worn out at 70 or 80 K on them.
I do not agree. I've never seen a 318 worn out at 70-80k miles, much less a /6. If they wore out it is simply because people did not take care of them
