....red line at 5,000 rpm? my VW van did 55mph My 1970 Westphalia was turning 3000 rpm at 50 mph also. It was relatively stock, other than some longevity mods. It's predecessor, a '71 9-passenger, was not stock, and just roared up hills - lots of fun passing tired old Datsuns on grades :) No matter the puissance of your motor though; at 70 mph Buses are getting light in the front end - Not the ideal vehicle to do a snap roll in... Side winds can blow you off the road, too. Ask me how I know...
