With a DZ tranny, I have to agree. There were 2 different ring and
pinion gearing ratios used in the 4 speed diesel Vanagons sold in the
US. If you have the more common 5.86 ratio DZ the stock diesel engine
won't do much over true 60 mph without screaming for mercy. If you have
the less common 5.43 ratio DM that at least came in some passenger
models you get about 5 mph more.

Don't bother telling me that yours does 70 no sweat. Vanagon speedos
like most others are generally optimistic. Put some 185/70/14  tires up
front and you can have the illusion of 75 mph but most semis will still
be passing you.
