Camaro350z28

Ok im just tryin to figure this out and what is a decent oil pressure. My car has 160k miles on it, its a 97 z28 m6. I figured with that many miles on the car my oil pressure wouldnt be as high as it is, in my opinion. I figured cold maybe the pressure be up a lil around 40 psi and then when it is hot down around 25-30 and maybe hittin 35-40 in the rpms. My car runs about 60 psi when cold and drops to around 35-40 when hot. and up to around the 60psi range in the rpms. Im just tryin to figure out my motor and if maybe someone thinks this motor was rebuilt at sometime in its life? or do you think its just a coinidence and higher oil pressure or is this normal for all lt1's? i bought the car with 153k miles. and im just tryin to figure out what i got and what your guys opinions are. thanks guys you always help
