Not all 261 blocks have the pin selector option. It does not matter what line size you use for a bypass setup as long as at some point in that bypass system you have a restriction point. My bypass setup has the restriction point in the filter made by FRAM(PB50. The bypass system would allow some of the oil to flow from the main gallery to the filter then run back into the pan. A full filter system will take all the oil from the gallery pass it thru a filter and return it back to the gallery going around the relocated pin or other means used to block the gallery.
