Oil pressure 502 efi/mpi
What kind of oil pressure is acceptable for these engines? I went for my first test run and both engines were between 25 and 40 depending on hot/cold, under load or idling, and I have slightly different reading for each engine. One runs a little weak on the pressure around 25 idle 38-40 under load while the other stays around 30 idle and 40 under load. Neither dropped below 25 or went above 40....

Those readings are pretty normal for a 502mpi. I see about 35-40 cruising, 45psi at WOT and 20-30 at idle depennding on how hard I was running. 502mpi's also use oil due to the low tension rings. Expect a qt of usage every 10-15hrs or so.
