The calculations we did for the now infamous "wear index" indicate that with
stock gearing and stock size tires, the engine in a '69 should be turning
3484 rpm at 60 mph. If your bus has ended up with a gearbox built in 1973
with a numerically higher 4 th gear, the result could be 3781 rpm at 60 mph.
The Haynes manual for 1600 buses also talks about something called "mountain
gears" which has a numerically higher final drive.
