Installing oil pump drive on a 360

You need to go to MyMopar and download yourself a free shop manual. Bear in mind that not all distributors have the drive tang in the same spot relative to the rotor postion. There are three ways to deal with this.........1, have the vacuum advance out of position, sometimes not an option. 2...Diddle with the gear position to compensate.....and 3......Put the gear in as the book, and just deal with the plug wires being rotated from "stock."

THERE IS NO REAL REASON to worry about the "right" position of no1 wire, other than "restore correct." The only reason "this ever was" was to

Allow pre cut wires to "lay" correctly in the hangers
and for tune-up mechanics to "see" what they expected to see
