Hello everyone ! The first day I'm with a Volvo 66 after a big restoration.
I have RPM 3000 - 60 km / h
4000 - 70 km / h
It is right ?
I think this is a high engine speed?

Hello,
That sounds a bit high to me
Constant speed on the flat with mine gives about 2000 rpm at 30 mph (50 km/h)
Accelerating gives more, and so would dragging brakes I expect.
If it’s not a vacuum leak on the diaphragms or pipes then look at the overdrive controls - mine had a leaky seal on the vacuum valve that meant the transmission didn’t change up enough

Should run between 1800 and 2200 rpm at 60kph. All mine do when new parts bedded in .
