I am building a 383 hp 4 speed with AC and N96 fresh air in b body, I can find a chart that would offer a Holley carb that would suited for this setup. thanks
 
I'm running a Holley Street Avenger 770 on my 383 and has been running great for 8 years now.

Your question is not real clear.

Holley carbs are all the same height. So if you are using the factory intake, you can use nearly any Holley carb to achieve the correct height stack-up for your N96 set-up.

We'll need to know a bit more about your engine to recommend which Holley carb. That said, I generally agree a 750-ish cfm carb can work. If you're not a hot rodder at all, a 650-ish cfm might suit your needs as well.
 
Works fine for me... 750 vacuum secondary, sitting on a 1/2" spacer/adapter.

running with factory intake
 
When I rebuilt the carb during the restoration, I downsized the main jets to 68's from 70's and it runs nice and clean on those..
 
So you are just trying to keep everything factory under the hood . What is it exactly that you have ? Year/make/model of your car ? That info is in most Factory Service Manuals. Do you have one ?

70 coronet 440 model originally with 318, now cloning to RT with 383 with A/C with N96 fresh air. Also have Factory Service Manual somewhere in a box.
 
If I remember correctly, mine is List#4749. The original owner told me that it got changed at one point. My 69 parts book lists R4440 for 69 383 with an automatic; part #2946538.
 
IMO...
Consider a Holley R-4668 a 4160 model with side hung floats. It was standard for a 1971 383 with A/C, although jetted for auto trans. It is rated at 750 CFM vacuum secondary down leg booster venturii. Can be converted to manual choke but original divorced choke operation. Just my opinion of course.

R-4367 is the correct Holley OE list number for the ’70 383 HP manual trans. No specific list numbers for N96 vs. non N96 for 1970. No Factory A/C with N96. R-4367 is likely pretty hard to find these days, as mentioned, there are some other similar list numbers for ’70-72. R-6515 was designed a bit later as a replacement for that series of OE 4160s.
