Thanks Dale. You can understand the confusion I am experiencing on this issue. I have heard the same thing you state below. Then I heard an opposing opinion. Just trying to insure what is considered normal.

FWIW, I talked to the guy that designed and sell the MasterLube pre-oilers and accumulators about using an accumulator to solve essentially the same concern. My car normally runs 35-40 at speed and drops to 8-12 range when warm and idling - especially at toll booths on the highway.He said it's not unusual to drop that low as long as it picks back up again once you start going. Like most others I've talked to about oil pressure, it's the initial cranking and startup that causes the most wear and long term damage.Check them out at http://www.masterlube.net/home.aspDale McIntosh

Subject: RE: [Chevelle-List] 383 Stroker Engine in 67 Chevelle=Oil Pressure too Low ???There is a plug in the passage just above where the rear main cap bolts in and if that plug isn't installed, the oil bypasses the oil filter and I believe the oil pressure is lower because of that. Just something to check. I dont know if that would be the first thing to check as it isn't an easy job unless the motor is out of the car. I built my 350 (my first motor by myself) and I have 20psi in drive warmed up (approx. 200degrees) and I didn't check if that was left in there when the block was bored. I wonder myself if that is causing it and haven't wanted to pull the engine back out to check it out yet either. Just something to check. Good luck.Brian Zack

Subject: [Chevelle-List] 383 Stroker Engine in 67 Chevelle=Oil Pressure too Low ???I posted this on the Team Chevelle Tech List and seek additional inputs from Chevelle and other auto experts. Thanks.
<I have a 383 stroker engine in my 67 Chevelle. The engine has supposedly 2500 miles on it. I have also just put in new autoguage meters.
The issue is the oil pressure readings. When starting at cold, the pressure is up around 40 plus. At warmup if I am driving it the 40 to 60 mph range, the oil pressure is in the 30 to 35 range, usually staying around 32.
However, at idle the oil pressure is around 10 to 12 psi. Sometimes it drops to 8 psi. If you put it in neutral at a stop light from drive (I have automatic trans), it will climb back up to 12 psi at idle. If you put it in reverse at idle it drops to 6 psi.
When accelerating again from idle the oil pressure goes up in increments, based on speed, to 30 to 32 psi--where it remains constant.My concern is the idle pressure. Is this oil pressure at idle too low and should it be higher ? Change oil pump or pick up tube ?
I have had conflicting opinions and seek addtional advice.
There is no blue smoke or knocking that I can detect at this time. Engine runs smooth and strong and I do not appear to be using or burning oil.
Thanks,
