An MSD distributor requires the intermediate gear slot in a different position to set number 1 at the front of your distributor. The slot doesn't point to the front intake bolt/port.
If rotor tip lines up with the drive tang, the std positioning is fine.
It's easy to change position, just takes a large, long flat blade screwdriver.
