If the # 1 spark plug wire is not above the notch, then the wrong cylinder
is being retarded, because the points rotated with the body. If the
rotation was 180 deg then the timing is being done off the "odd" cam lobe
and the other three cylinders are running advanced. I agree that this might
not be possible due to interference between the vac advance and the fan housing.
If the drive gear is installed wrong and the distributor is just turned to
match it then there is no problem except poor fit of the vacuum advance and
plug wires.
This is just another example of a case where it is just better to do it by
the book.
