what's everybodys oil pressure hot, at idle?

my oil pressure cold is 60psi. when it warms up, and at idle, its appx 20psi. just wondering if anybody else is near the same. also, temp got up to appx 235? (just before mark between 220 and 260) with a/c on and sitting in traffic. dropped to 220 while driving. just polling to see what you guy are running. thanks, tom

It's around 50psi cold @idle, when hot the rule of thumb is 10psi for every 1k rpms, mine is right with that, just a little more.

No, but the 305 was about the same, except when cold, if I remember correctly.

60 when it's cold, 15 at idle (operating temp) and 30 under load (warm).
