My 422 smallblock build
I shortened the pipe plug to .285” so I would not protrude into the oil passage leading to the #1 main. Drilled a .0625” hole in the center of the pipe plug to oil the timing chain with a steady stream of oil. Drilled a .250” hole in the cam retention plate to allow the oil stream to get through.
