around town at under 2k short shifting It stays under 40... consistently.. I'd have to say 37ish'


WOT=lowww 50's or maybe just 50.

I know my LS1 has a good 60 hot when WOT...but I don't think you have anything to worry about. I know more about LT1 oil pressure and mine only gets 39psi WOT...general rule is 10psi per 1000rpm so 50 doesn't sound that bad...but I will let others who know more about it chime in.

I personally wouldn't worry about it.

Very close to the numbers on my '98 w/ 50K miles.
45-50 psi cold idle
40 psi hot @ 2k rpm
35-38 hot idle
Running 5W30 dino oil

I wouldn't worry about your oil pressure numbers.

Change the oil. A dirty filter will lower your oil pressure.
