oil pressure within spec?

[combustion]

up untill the point i installed my 454, i never really looked at my oil pressure guage.it never drops down below 1/4 of the way down. here is what my guage indicates.

fully warm @ idle 650-700 rpms




should i be worried?

other info..

when its cold it pegs all the way to the h because the viscosity of the oil is thicker.

also when im reved to about 1500 rpm's (FULLY WARM) it goes about 3/4 up closer to the H. which is good. anything past 1500 it pegs the H (FULLY WARM). <-- this is normal right?

so in a nutshell, should i be worries about my idle oil pressure? is it too low at idle?
