just recentley did a le2 package and when i start the car when its cold i get about 40 psi. but then when it warms up a little bit it goes to 20 and then it slowley drops to the redline. when it gets warmer or running temp the check gauges light comes on and i have like almost no oil press but when i rev it it goes to like 25 psi. i have a really low idle when its warmed up i still need a tune and bigger injectors. im also running open y pipe if this helps. i dont know whats going on. before i did the heads and cam swap i had no problems. oil press was 20 at idle and 40 above idle. im running 20 w 50 non synthetic oil.

 

My want to start saving for a new shortblock

 

have someone sit in the car and watch the guage whilst you pop the hood and wiggle the oil pressure sending unit (on the back of the intake) if it moves around a bit that may be your problem ~25 bux i think.
