Andy, Nice engine. You made the comment that a bigger pump would help your internal vacumn. Woundn't a smaller pan also help with that. I have never heard the bigger pan thing when talking dry sump, just add more sections if you need more internal vac and oil control. My 358 with a 5 section barns pulls 17lbs. I know its less cubes but your dry sump should be making some sort of vac. Jon
