Coolant and oil temperature, as well as idle speed at V8…

Moin Where exactly does the temperature display for the cool water have to stand, with a warm motor? The oil temperature is at just over 60° , somehow little after 20km driving. And then the empty speed. How much is normal with the 3.6 V8? Sometimes it seems a little too low to me, and when you give gas it swallows up, the speed goes short into the cellar and then up first. So it takes on delayed gas, but also not always. Is already the V8 time, from which I no longer know exactly how my old has behaved Here still pictures of the instruments.
