I'm not sure the search is over for two reasons.
First, a confirmed late build that is different than all the "bad" parts books may or may not be accurate for the preceeding months, although in a vacuum I would agree it is better than nothing.
Second, no one has yet answered the question about the physical difference(s) between N96 carbs and their equivalent non-N96 counterparts (regardless of engine).
Why do you think there should be a different carb. made for a 70 440+4 non N96 car and one with N96?? There were none made for 70 340 cars, N96 or not, same goes for 71 340 TQ equipped cars, nothing special made for a car with or without N96. In fact it looks like Carter carbs did not cater to the N96 code. Only Holly issued different carbs for that option. As far as differences go, check column 38 for the 70 Holley 383+4 4367 manual non N96 parts listings, and check the 68 column for the 70 383+4 manual N96 parts listings. There ARE differences between the two.

does anyone have a pic of one of these (70 b and e 383 auto N96 cars) or any idea how it differs from the non N96 cars? thanks
I thought those had bigger secondary diameters or something. I have one dissassembled. I thought the Mopar parts book listed those carbs specifically for fresh air applications??
Here are a couple of pics of the R4368 (1970 383 N96 Auto) carb that I am running on my Bee. I have the original 4368 sitting on a shelf because the threads for the squirter are stripped (acually distingrated in the carb main body)
Anyway here is the drivers side of the carb. The wire off the front bowl is the ground wire for the electric retard solonoid on the vacuum advance. Also the rectangular plate on the drivers side below the top of the air horn is the houses the "Hot Idle Compensator" valve (a bi-metalic piece that opens an air-blead when hot) think of it as early emmisions stuff..
The only deviation this carb has from being completely original is the primary bowl is a replacement (it does not have the vent baffle hole on the top of the primary bowl which I have on the numbers matching carb). I took it off because I did not like the fuel slopping around the on the outside of the carb which was common with that bowl.

Relax Dwight, you get no argument from me. What I have apparently without success been trying to point out is that no one has ever articulated in a thread here exactly what those differences are, although the question has been asked quite a few times. Finally in this thread it was revealed the secondaries are larger. Anyone know of any other differences, either internally or physically?
I'm asking primarily because I know I am not the only one who has added a shaker and does not have an original 4368. This would be useful info for those of us trying to make do with a 4367.
Which takes us full circle back to 92irocturbo's original question: "What is the difference between 1970 E and B body carbs for a 383, both N96 and non-N96?"
Until total honesty is on the table, we're not even talking about reality...

If you refer to the 1970 factory Service manual, there are speciations for a total of 5 Holley 4160 series carburetors for the 383. With the exception of one fast idle speed spec. all other listed specs are identical including the diameter of the throttle bores and venturies. No mention of Fresh Air, F/air, Air Grabber, or N96. Of the three open bowl vent carbs (C.A.S. or 49 state versions) there is one for the manual trans (R-4367A) and two automatic trans versions with and without AIR conditioning (R-4369A and R-4368A). AIR conditioning-Fresh AIR, what if the some of the 70’ parts tables from the day reflect a simple type error? I owned a 70 RR 383 4-speed N96 car with it's oringinal R-4367A Holley back in the day and spent a great deal of time deciphering Holley carb numbers, came to the conclusion back then that some of the parts information published at that time was wrong in reguards to "w F/Air" and that there never was a N96 carb. It amazes me that people are still talking about this 39+ years later.
