Terius' 350 1st generation Chevy small block runs 25 hot and is at 70 at 2000 RPM hot and will bury the 100PSI hot gauge if you rev it on up. AS SOON AS your big toe is on the gas, the gauge hits 40 PSI. It has an HV pump that I installed in it myself. Also, at 20PSI HOT at idle, is has oil RUNNING off the rockers, so it has plenty of oil pressure up top. I'm not arguing about it one way or the other, simply letting yall know what my observations ARE. High volume does not always mean high pressure. That's why some of them come with a high pressure spring SEPARATELY.
