The Ford Barn - View Single Post - lowest oil pressure for engine to survive

I run a 286 CI 8-BA with 20-50 oil. Runs about 50 psi at start up but when hot about 10 psi at idle. Have not had any problems in 10 years or more. I've been told that it isn't about oil pressure with a flathead it's about flow. Just my experience and I run it hard.
