What Should The Oil Pressure Be On A Big Block 454 Chevrolet And Operating Temperature

When Im on the gas the oil pressure stays at around 65-70, when its at idle and the engine is warmed up it drops down and hovers around 40. Is this where it should be? If not what is the cause and what can I do to fix this.

My engine likes to stay at around 165-170F, but when its hot out it goes up to about 190F. What should the operating temperature be? And at what point is it too hot? Ive always heard bigblocks do not like the heat so Im concerned. Thanks for the help!

I have a 454 with aluminum Dart heads, hydr. roller camshaft, roller rockers, .030 over and some other things. 4 core radiator and electric fans, MSD Ignition.
