You have old posts and threads about schwalms, insert bearings, and oil. You mentioned that schwalms recommended 15W40 for your motor and you were happy... what has changed since then?? As with any oil thread your going to get different reccomendations so why not just continuing with got your motor this far. The AER website reccommends 5W30. Schwalms as u mentioned 15W40. I dont get what info your looking for..
If your just trying to get a survey going there was one done a while ago by Bob Johnson which should be in the archives
