:disco: For all the engine builders...What bearing do you typically use in a blown app? I have used Clevite77 'P' series (not happy) and I am trying ACL (have not disassembled yet). What should I be using. Since not all bearings are created equally I am not interested in what works on "Joe's" turbo motor or "Buddy's" n/a motor. I want to know what takes the punishment and heat of a roots blown engine the best.
