exrernal pump is the same as the dry sump except the oil is in the pan . no need for internal pump drillingJust talked to Bob, nice guy. I'm very interested in the short block, just have 1 question maybe Charlie (or anyone else), can answer.... I'm not familiar with the A96 block. Bob says he ran a dry sump on it and that the block isn't drilled for an internal oil pump. I was planning on running an external pump, just not a dry sump. That should be basically the same setup, right?
