An A35 van was just about flat out at that speed, about 5000 revs on a 3 bearing crank. In those days the original A series engine was the mainstay of all the smaller BMC range. Being a relatively longstroke design, most hard driven commercials needed a rebore at 30000 miles. I drove one for a living, local deliveries. Great fun, slim enough to whiteline down wide A roads. Handbrake on the right, between driver's seat and door panel, indicator switch on the dash top. Brakes..hydraulic drums on the front, rears...cable from a third slave cylinder, if I remember. Yes, it was a long time ago.
Swarfy.
