Whether auto or 4-speed, I have never seen a direct answer posted on here as to what the exact differences are in 1970 E and B body carbs, with and without N96. Question has been asked many times, but nothing firm or authoritative has ever been answered.
Until total honesty is on the table, we're not even talking about reality...

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??

Yes it does, at least for 383s. There are separate numbers for:
* Auto with N96 * Auto without N6 * 4-speed with N96 * 4-speed without N6
Please post the numbers and source you are quoting from, the 70 only parts book or the combined 70/71 book?

I ran into this same problem when adding a real shaker setup to mine. Due to the rarity of 383 shakers, I was only able to locate a non-N96 carb. Wanted to know any performance differences, but also needed to ensure the physical dimensions would put the bubble at the right height.
I've seen many answers here over the years stating that they indeed are all separate part numbers, but never a definitive explanation of why.
IIRC, it's in the thottle bores. I've had someone show me a non N96 holley next to a N96 one before. But that was nearly 20 years ago. I think it was Bob Harris at Mazzolini's shop.

I'm pretty sure it was the combined book for me. But that's a very good question because the combined book is known as having inaccuracies.

Well iceman, that means the search is over. Iroc, can you post a pic. of your broadcast sheet for us??
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).

My build sheet codes on my 70 Coronet 383 4 bbl manual is for a Holley R4367A with the code on the sheet being 36. The carb on the car is a Holley 4749 however. The origianl owner swears it was rebuilt once but it is the original carb. I am thinking it is a service replacement but cant find it in the paperwork.
Anyone know what a Holley 4749 came on?
77 Macho Power Wagon LWB factory 440
70 Coronet 440 N code 3 speed
