Right - the distributor can go in in either of 2 positions, 180 degrees apart. And it's not a good assumption that the oil pump has been installed exactly as it was at the factory so the picture in the wiring diagram of where #1 plug wire is can be unreliable. The standard method (other than trial and error) is to remove the #1 spark plug, turn the engine slowly (best by hand) in it's proper rotational direction until you feel compression coming from the #1 cylinder and then stop the rotation at the timing mark. Then whereever the rotor is will be #1 plug and just put the rest in order, following the direction of rotation.
