If it is your intent to use the top mounted factory oil pressure sensor on LS2/LS3/LS7/LSX engines, you will need to carefully drill and tap the oil pressure sensor provision using the pre-located pilot hole on the bottom of the valley cover. The hole should be drilled and tapped to accept an M16 x 1.5 male NPT fitting.
