lowest oil pressure for engine to survive

[Adam/Mill Valley CA]

Trying to resurrect this old thread, any update as to how this tired old motor has done after replacing the oil pump with a #80 high output pump a couple of years ago?

Hey, old Chevies of that era didn't even have any oil pressure. Strictly splash!

Yep but the oil flowing into the dippers created 70lbs pressure in the rod bearings.

Pretty sure it blew uo and he had to resort to getting a nova.

Lots of flatheads run low oil pressure. Pressure is just resistance to flow. As long as there is a a few pounds at idle, you are fine.
