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...

N96 (Fresh Air hood/Shaker) has no specific listing, 4737 is listed to cover any of them regardless of the hood/AC package. 4739 AVS is the 440 manual trans N95 carb. 5026923-19704404speed4737AVS.jpg (535 downloads)

I have one dissassembled. I thought the Mopar parts book listed those carbs specifically for fresh air applications??

There are separate numbers for: * Auto with N96 * Auto without N6 * 4-speed with N96 * 4-speed without N6 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.

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.

UP FM3challenger OP member Joined: May 2005 Posts: 153 Gladstone, Michigan	i've run into alot of confusion with the 440 carter 4737 carb, the 383 N96 was a holley. The last one I saw for sale was a couple years ago, the owner swore it came from a 428 cj mustang and wanted a mint, maybe I shoulda bit

I can take no credit for that! Have you checked the very accurate Service Manual for 1970 carbs(Plymouth or Dodge will both be the same). It is an excellent source for information on all these questions, both Carter and Holley.

UP FM3challenger OP member Joined: May 2005 Posts: 153 Gladstone, Michigan	holley shows the part number for a 4737 as 3512965 which would correspond to the broadcast sheet.

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). Until total honesty is on the table, we're not even talking about reality...

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
