Quote: Clearances are probably on the loose side. Also high volume isn't the same as high pressure. I use a high pressure spring in any modified engine. With 20-50 weight oil my cold pressure is 75-80 psi. Hot idle is 40 psi, 30 psi if it's been run hard. Hot pressure at 2000 rpm is 60-65 psi. Pressure is 5 psi lower when using thinner oils. Most stock Mopars run 45-50 psi at 2000 rpm hot and anything from 15-30 psi at hot idle.
