I've been looking around this site at oil pressure threads.whas the normal pressure and problems with it. Any way idk if it's bad, my 99 z28 bolt on,when I first got her oil wasn't that good.had a bad oil pressure sending unit.and still marked 50 at cold start and 30-35 when hot.

I changed the intake Mani to a ls6 and replaced the oil pressure sending unit,changed oil to Mobil 1. 10w30..used a knn oil filter, but idk if it got damaged(Mabe beaing the problem).i was installing it and used some pliers for oil filters to give it a goot tight grip. It kinda bent it from te sides.
Now my oil pressure at cold start is 40 and when hot 25 20,..any ideas why?
How's ur oils pressure cold and hot ?

~70 when cold
~55-60 warm

It's a used engine that got installed by my insurance company. They replaced the sending unit at the time, so I'm assuming it's right on. Is it fair to guess it has an aftermarket oil pump on it?

I wouldnt worry man, you have high miles but its a ls1. id keep rockin and rolling until she goes, no worries. only time to worry is when it says 0

I get around 55-60 cold and 25-30 warm. This is with a GM high volume oil pump. I just did a complete h/c swap with the new pump so my thought is the stock oil pressure gauge is basically a dummy gauge. Shouldn't I be reading higher psi than this?
