It depends what condition the engine and drive train is in.  a noisy diff or gearbox will make it very tiring.  I averaged 80mph across Belgium in 2011 with a mildly tuned 1098. the exhaust was dreadful and very noisy even though it was a TI Bainbridge steel unit.  Stainless units are noisier.
I have a 3.9 diff in now which is noisy but the engine is quieter. i would say 60 is a comfortable speed on the flat.

Flat out, a standard 1098cc will nudge 80 mph (I gather the official top speed was 78 mph), but they cruise comfortably at 60-65mph or so.

I tend to go about 55-65 depending on whether I can be bothered overtaking trucks. I like to stick to 62 for some reason. That#s with both cars, they are very similar.

With one in tow, I'm not surprised ;)
Just to add to the mix, my 950 engined Minor I have never had it over 60 for any length of time, 50 is max cruising speed. It's worn out though, although the oil pressure seems good.

They will easily do 60-65 all day long, 100+miles. As said, you can get to a tad over 80 in a standard 1098, but thats pushing it mega.

When you check the 80mph on the speedo, it's amazing how close it is to the 74mph on the specifications!

Some forty years ago I had a 918 side valve mm I seem to remember 64 was flat out and 50-55 was a reasonable cruising speed

I've found that each of the various Minors I've owned over the years has had a slightly different speed at which they're "happy" cruising. When we took our 948 car abroad it cruised comfortably for an hour or two at a time on the motorways at 60-65mph. The 1098 car has a slightly higher top speed but various vibrations mean that the car doesn't feel comfortable maintaining speeds of much more than that for long periods.
In all honesty, whatever engine and gearbox you fit, the Minor produces quite a bit of wind noise etc so will never make a great motorway car!
As someone else has already found, the Minor speedo is not the most accurate instrument in many cases and tales of cars which will go "round the fuel gauge" are probably largely the result of an optimistic speedometer :raz:
