I really wonder if they were drilled from both ends. There are oil galley plugs on both ends of the block. It's hard to drill 30" through cast iron with out the drill leading off. I have read in Hot rodding Mopar small block books that you can drill the galleys out to the same size for more even oiling.
Now that would make sense; it is easy to see the drills being off-angle from both ends. You may have solved the mystery.....do you prefer the moniker of Holmes or Clueseau? LOL Tnx
