Oil pressure

[Ben Raines]

I have a 73 vette with a ZZ4 motor (less than 1000 miles). Running at approx. 2800 RPM, my oil pressure reads around 63 psi. Is this to high? At idle, pressure reads around 20 psi. I'm using Mobile 1 synth. oil. Thanks

Re: Oil pressure

My ZZ1 crate engine in my 70 at startup with 5W30 Mobil One almost pegs the guage to the right. Pressure after warmup is less, the ZZ1 does hold a higher oil pressure under normal driving conditions than my original 350/300.
