You might want to post photos and mention the year of the 261.
From 58-63 there is are two 1/2" NPT holes/plug on the driver's side. There is a movable plug inside the rearward hole that diverts full-flow oil out that hole. If that plug is moved to divert oil out the 1/2" NPT hole, that hole in the block should not be plugged.
