Distributor Spark Plug Wire Orientation

Yesterday I verified the firing order and spark plug wiring.

I noticed something strange.

The normal orientation of the #1 spark plug wire is at 12 oc'clock with the 12 o'clock pointing to the front of the vehicle.

My distributor was set up by the previous owner by having the #1 wire at the 9 o'clock position; so all wires are in the right order, but shifted by 90 degrees. The engine starts and runs fine. I think it could have a little more power on acceleration. That was the resaon that I started to check the spark plug wire orientation.

Can any one gives me ideas as to what is going on?

The vacumn advance is in the proper 2 o'clock position.
