Just curious, what should the oil pressure be at or around for a 383 stroker engine while the car idles?

Thanks!

I like my engines to have around 20 psi at idle. But I've always been told as long as you have as little as 5 psi, it's alright. Just depends on clearances when the engine was put together.

My 383 oil press is 70 lbs cold and 20 lbs hot at idle.
I'm using 10-40 oil. Idle rpm is at 600.

Mine's running around 40-50 psi hot at idle with an rpm at around 800. 600 seems kinda low, does your car stall if you don't warm it up for 3-5 minutes? Assuming you don't drive it every day.

I also use 10-40, from Valvoline, but the oil seemed a tad bit low today and all that was open at the time was Chevron, so I put in a quart of their name brand stuff. My dad was saying that it's recommended to try and stick with the same brand of oil, hopefully I didn't scew anything up by adding a different brand then I normally use, it was the same weight though 10-40.

Last question, do you guys ever notice any fluid on the ground, even small amounts?

I know a lot of guys that use valvoline and they have no troubles at all.
I'm using penzoil in the 383 and yes I do stick with the same brand oil.
Thats what I was told a long time ago so thats what what I do.
I don't think you did any harm by adding a quart of a different brand oil.
What type of oil press gauge are you using?
I'm using a mechanical with plastic tube. ( copper tube too noisy for me)
There may be a slight difference with the readings of a mech gauge vs.
a electric gauge.

Mine's a mechanical gauge also. Do you ever have any oil leaks? Mine's been dropping a few drops here and there lately, it's frustrating.
