Hi guys! What is a good oilpressure in a 68 383?
Yep, factory service manual says 45-60 at 1000 RPM.45-50 lbs for a stock BB Mopar engine, is normal.
Why do you ask? What are your concerns? What oil pressure are you seeing?Hi guys! What is a good oilpressure in a 68 383?
Sorry, but this is not accurate enough of a response.45-50 lbs for a stock BB Mopar engine, is normal.
What part of 'stock' don't you understand?Sorry, but this is not accurate enough of a response.
At 6000 rpm you should have at least 3000 psiSorry, but this is not accurate enough of a response.
45-50 lbs when? At idle? At 6000 rpms? with an old engine or a fresh rebuild? Thick oil or thin?
Too many variables to pin down without the OP responding with more info.
Relax. Just writing a number like 45-50 lbs is pointless until you give it context. You didn't mention at what rpm, what oil or what temperature. Your number is a good one but it gives no reference to anything. 60 wt oil with a worn out engine can generate that number at 4000 rpms.What part of 'stock' don't you understand?
My 440, once it's fired up, has 50 lbs. Stays there, until it's warmed up. 3000 rpm stays there. Once warm, at idle, it's 25-30 lbs. Engine is mostly stock, though with a 1/2" oil pick-up, with a stock oil pump.
They call 'em that for a reason, my friend.What if you only have an idiot light and no guage?
His original answer? Not so much, because oil pressure in an engine is stated at a given RPM - so half his response was missing.One might argue that it's the OP's lack of context that is the issue. In light of the question, Miller's responds is as good as any.
My answer to to question would be 10 to 90 psi.

When in doubt, spout off factory numbers like I did - and hope the OP actually returns to finish his question.But what rpm? Are we suppose to guess what rpm the OP wants, or just give it to him in 5 rpm increments? And what kind of 383? For what purpose? Between the pump type, bearing clearance, and oil viscosity any answer could be right or wrong.
An OP should not expect any better of an answer than he/she is willing to put into the question.

The light that comes on ten minutes after the tow truck gets there!
