Sounds like a 10296 or maybe 10355.
Stock LS1 pressure is around 25-30 hot idle, 50ish at full blast.
Not aware of any particular "minimum" or "maximum". Although I personally wouldn't ever want any less than 15 or so under any circumstances whatsoever, and if the motor didn't have at least 200k miles on it, I wouldn't accept that either.
