Here is the next video from my you tube channel, DragBoss Garage. This video shows the installation of the external oil line, and the 2168 oil filter adapter, from TrackBoss Performance Products. From what I have heard, that the oil filter adapter, allows for increased volume, and utilizes the Wix 1268 filter, instead of the Wix 51515. I included the specs, so review and make your own decision. I also wanted to try the external line, that adds a bit more to the rear oil galley that the sending unit screws into. The theory is that it adds more oil to that galley, that feeds the 5 th main bearing, and the left side galley. I thought I would try it and see how it goes. I listed oil filter specs at the end of the video. I am also giving a shout out to Mike Weaks for helping me with running the 409C on run stand before the trek to the Dyno. Alos Ronald Berges for helping me achieve my goals. Thanks Guys...stay tuned.
