Maybe. I've always ran a big pump. We had some issues early on losing oil pressure in the shut down area. Changes in the pan design and an accusump helped with that. I'm just illustrating that there's a lot of oil going places it doesn't need to instead of being kept on the crank. That's fine in a stock application that rarely sees more than 3K. I've also never tried to run a hydraulic cam to the RPMs I'm thinking about here. If I did, or if I oiled the top end through the pushrods, I would bush the lifters and control the amount of oil on the lifters.
