The 93 doesn't time the car based on distributor position. The dist is simply used to contain the cap and rotor and point the spark at the correct wire.

Even if you moved the dist a few degrees either way, it wouldn't affect when the coil fires. You can't really turn it anyway, if the rubber block is installed in the dist body adjusting slot- older cars used the slot but the crank-triggered cars (such as yours) block off the slot with a special spacer.

The only thing you could conceivably do to it is to leave the spacer piece out, and turn the dist SO MUCH that the rotor wouldn't be aligned to a wire contact in the dist cap. I'm not even sure if it gives you that much adjustment range, because there's really no need to try it- you're still not adjusting ignition advance no matter what you do.
