I'm not sure, I thought someone told me they went to single point in 71? Why would someone switch it? Maybe easier to adjust? I hope someone chimes in to tell us.. Thanks, Craig.

I just looked it up on Moparts.There was a post about single point distributors.1971 340 Auto's had single,4 speeds had dual. At least that is what the post said? Craig.
It could also be from the "Hemi Kellogg crank syndrome". Since the Hemi and 440 have the same stroke, many people that sell their Hemis trade cranks and keep the "good one (Kellogg)" for their 440s and give the buyer the weaker 440 crank with the Hemi.
I could see someone who sells a 340 exchanging the dual point with a standard 318 dist to keep the "good one" for themselves. I will go back into my "library" of service manuals and see if that checks out.
I am restoring a 71 Challenger convertible with a 340 and I believe that it came with a dual point distributor. It was a pain in the butt to adjust both sets of points and get the proper dwell... Single points are much easier to set up.

don't forget that late build 71's could also have electronic
How could that be? The electronic did not take over across the board until 73.

Very Rare to find a 71 with elec ign. bulletin came out on may 6 71 but the switchover was more around june 1st and even then most were getting points, the code for electronic ign is N23.
Interesting. If you read the bulletin, only the four speed 340's were getting the electronic ign. Is this the only engine that got it, or did they release other bulletins for the other engines? Also if the changeover was in June, it was only for the last month of production as they change over to the new model in the middle of June and begin in early July.
What did they build out the automatic 340s with in 71? Then did all four speed 340s get electronic ignition in 72? Then why is the electronic ignition considered to be changed in 73 across the board if they pulled the change ahead like the 71 340 four speeds? How did you get a hold of this TSB?

Is yours a four speed or auto? A or E body?
