I am doing final assembly of my 427 and when I turned it over to install the windage tray I found what looks like an
oil passage on the left rear bottom side slightly outside where the
oil pan rests.
The passage goes vertically to the
oil bypass valve at the rear of th block...
Stupid question, but I am assuming my machinist removed it for cleaning and didn't replace it.. It looks like it could be 1/4 SAE thread, (1/8 pipe is too big).
Does this passage get a plug? Is it anything special? Also I read in shimming the bypass valve 3/16 of an inch one can gain oil pressure? Any thoughts..
