Technical Is this enough oil pressure for a Lincoln 337?

Hello! I’m planning on buying a 1950 Lincoln cosmopolitan with a 337 Flathead V8 this week. According to the aftermarket oil gauge cold, it gets 12-15psi of oil pressure at idle and a little over 50 at speed. I’m going to see if I can have the guy see what it is when it’s warm but this is the baseline at least. I should add the engine seems to run really well and it doesn’t smoke, despite being unrestored to my understanding. What do y’all think? Thanks for the info you can give me!

 

As Anthony would say, "I'd drive it!"

 

Factory spec for an 8BA is 55-57 psi at 40 mph. I can't imaging that a Lincoln would need much more. I looked through a bunch of old Motor Repair Manuals , and the highest pressure I could find specified for anything was 60 psi @ 40 mph for an early Chrysler hemi. BTW, that the 8BA pulls the second highest normal oil pressure I could find, contradicts the postings I have seen here and on other forums that a "flathead is a low oil pressure engine". I have seen it posted several times. (That's for Model "A"'s and 216 stovebolts.)

 

Chilton's Manual 1940-1953 says : 50lbs @ 40MPH / lower limit 25lbs for Lincoln 337

 

I was taught 10psi per 1000 engine rpm. Didn't matter if it was flathead, overhead or diesel. Anything greater than that was a waste of energy.

The rebuilt 337 I ran for several years would go under 10 rpm at idle without any hiccups. Drive it and enjoy it!

 

Okay quick update, at temp the car gets around 10-12psi at idle and around 50psi going down the road.

 

that's over 10 psi per 1000 rpm, eh? sounds good to me

 

I use the 10 psi per 1000 rpm formula as well as all my stuff is worn out but still works!
