351 W oil pressure

eleanor_350 · 05-01-2003, 12:10 PM

I have got a 65 coupe that I've installed a 351 w and toploader 4spd in. I've only put about 2000 miles on it since it was rebuilt. At highway speeds my oil pressure is 50 psi or so. But at idle (about 700 rpm) it drops down to 18-20 psi. Is that enough oil pressure?

The general rule is that you want 10 psi oil pressure for every 1000 RPM. So 10 psi to 60 psi for your engine is probably OK.
