EDIT: READ PAST THIS FIRST SECTION
Sorry, no You went to a lot of work for nothing. The dual pickup dist (so far as I know) has no advance mechanism, and was designed to work with lean burn.
You need to find a "regular" single pickup dist with vacuum and mechanical advance, and substitute that and then wire it direct to the ignition module.
AND I MAY BE INCORRECT
You also need to pay attention to pickup polarity, because if reversed, it changes what is called "rotor phasing." (search that.) Rotor phasing changes the time/ timing / degree relationship of the spark firing point with where the rotor is or should be relative to the cap tower contacts
THESE threads. Evidently some did have vacuum advance. But I do not believe they had mechanical
YOU CAN TELL by springing the rotor while holding the shaft. If you can move the rotor in the same direction as the dist rotates, and it then "springs back" it has mechanical advance. Whether, however, it curve is decent is doubtful

Or maybe not. This guy claims some slant sixes did indeed, read:

"What Russ said applies to V8's only. In the early eighties some six cylinder cars had the dual pickup distributors but were not lean-burn equipped. The distributor had a normal vacuum advance mounted on it and used the familiar old Chrysler Electronic ignition. I had an 81 Diplomat with this setup. The dual pickup distributor, V8 or /6, was not a performance item, the car started on one pickup and ran on the other, controlled by a relay. The engine never runs using both pickups at the same time."
If that last is true, I'd be temped to try connecting the "run" pickup and check the timing and advance and see where you stand
