Pressure around 35# at idle. Up to 40-45 at hwy speeds.

Oil temp is relative to how hard you are driving it, in my opinion. After some spirited driving, oil temps of 220+ are not unusal. Mine usually runs around 215 degrees after being thoroughly warmed up on a reasonable hot summer day.

That's one reason why GM recommends Mobile 1 oil in our Corvettes.

Minimum oil pressure - hot:

6 psig at 1000 rpm

18 psig at 2000 rpm

24 psig at 4000 rpm
