Edelbrock AVS2 Series Carburetors

[@maxxmasson4263]

Best carburetor I've installed in 45 years

[@heisenfeis]

Really like this carb on my 1977 caprice sedan. i live in Norway, so not every day you bump into old classics, and its fun. The car is also my daily driver and this carb at 650 cfm is giving much needed fuel to my 350 sbc. Only thing i noticed is that the screws are almost all the way in after adjustment hehe, but i plan on putting some new aluminium heads on it which i hope frees up the carb a little more. i'm very pleased at the cheap price of 450 dollars (including tax and shipping). Transition between secondary and primary is noticeable, feels like injection or tbi, and releases loads of power :) .Thanks Edelbrock, your carbs are the best!

[@antoniocataneo5513]

heisenfeis have you an automatic transmission??

[@Layzie2500]

This carburetor is worth the money, the throttle response is crisp and smooth acceleration.

[@zragevii4705]

basically an improved quadrajet from what I understand.

[@jamiedeatherage3757]

Its a wild child on. my 99 355sbc S10 and even better with the 5SP stick shift I installed the 650cc AVS Thunder Series 4barrel. It loves turnin the tires.

[@SOLDOZER]

@@zragevii4705 Not even close to a Quadrajet.

[@Texassince1836]

I'm more of a Rochestor fan, I run Quadrajets on my C10s (one of which is a Vortec headed 350 320hp/400ftlbs) but on pawapws '77 C10 its had a 2101/1405 combo on it since he bought it. The 1405 has seen better days, and the lack of electric choke was annoying Rather than try to track down a 40 year old Rochestor and get fix it up we decided to go with a 1906 Edelbrock. I'm actually rather impressed with it. The annular flow boosters are definitely an improvement over the traditional downleg (and the electric choke is nice too)

[@EdelbrockTV]

We are glad to hear you like your AVS2 : )

[@mkowboy13]

This is so awesome can’t wait to try this out on the Cyclone just gotta install it, it’s sitting in me livin room lol

[@mortenhjorth-johansen5541]

I put an 500 cfm AVs2 on my Mustang with Edelbrock alu heads and AirGap intake.. Works fine, almost as EFI.

[@ThomasShelby-uq8cz]

What size engine? A 500cfm is most likely too small with a good set of heads

[@mortenhjorth-johansen5541]

@@ThomasShelby-uq8cz 289. However, it lagged when kick down, so I switched back to a regular 600cfm (1902) and all was fine

[@pepsiccolausa8857]

Use to be a holly guy but switch to Edelbrock since holly is now made in China along with msd

[@angelsanchez3074]

Picked the right guy for the video, he new what he was talking about a total car guy with the DJ voice. lol Good Job

[@SOLDOZER]

Quadrajet been around 50 years. These Edelbroke are in a landfill in under 10 years.

[@psychotrucker9880]

I need the 4300 squirter to make my transition from 2 to 4 smooth. I have been trying to buy part number 1475 for over two months. Everyone is on backorder and summit keeps pushing up the date. If you don't have parts for your carb 1905 then stop selling it. I had to put my Holley DP back on. Never had a problem getting parts for it.

[@gorybonghit3211]

Absolutely agree

[@Shockresistant]

Looking forward to the 800 cfm version for my 1971 Lincoln MKIII w/ 10.5:1 460 CID V8. Any updated release date? They kept saying "this summer" but summer's almost over. Can't wait for better part throttle and off idle performance vs older models. Take my money already!!

[@richardreyes891]

I want an 800cfm for my 10.75:1 Pontiac 400! I feel your pain!

[@mr.pickles810]

@@richardreyes891 you got any videos of this 400? Was given one curious to what theyre like

[@npp3559]

[@johnbehneman1546]

THANK YOU SO MUCH.

[@waynep343]

are there going to be changeable idle feed restrictions to fine tune the engine fuel needs from just off idle to when the primary booster has enough air flow to start flowing about 1900 RPMs.. this is where the fuel economy can be made.. and crazy fast off idle throttle response.. the new annular flow boosters work great when flowing .. there is something known as the LOW SPEED CIrcuit that needs to be tuned to match the engine displacement.

[@CraigFulton]

Poor Chris Eidem didn't even hook up the fuel to his carb hahahaha Along with the choke wiring and front right intake bolt.

[@Mr1980cadillac]

🤣

[@camaro3gen]

I need a tuning kit for my 650 AVS2

[@debonairecatalina6570]

I wonder if they can make a kit to improve the Rochester 2g's, tri power would be even better

[@matthewmiller2268]

Why aren't the secondaries annular discharge as well?

[@thedobermangang3503]

got question for you ....i just rebuild my chevy 350 1990 k5 blazer i converted it over from tbi to carb ..i did a few up grade on the engine high performance intake headers 3' pipes all way back up graded the cam to a howard rattler cam 525 intake lift 535 exhaust duration 227/235 lobe separation 109 center line 103 i still the same factory heads on there i believe they the swirl port heads ..i no i should have went with some better heads but the engine was already done. i put a brand new 1406 edelbrock carb on it right out the box every sence i put that carb on there i been using alot of fuel i set the carb best as posible ..im using a awful lot of fuel just with it iding..i have my pressure regulator set at 5psi..dont no why im losing so mush fuel

[@Squarebody_Builds]

The guy in the Charger doesn't even have the electric choke hooked up. Sure sign hes blowing smoke.

[@jimdouglasgregory]

When is the 800 cfm avs 2 coming? Also are the booster compatible with older Edelbrock carbs? Could you sell the boosters to retrofit in my current 800 cfm preformer?

[@EdelbrockTV]

the 800 series should be available later this year. We will not be offering boosters on their own.

[@jimdouglasgregory]

Sidecardbob how did you modify the booster?

[@jimdouglasgregory]

Sidecardbob where your inserts just straight on the inside? Don't annular boosters also have to have their own ventri shape on the inside so as to induce a increase in velocity thru the booster? The pictures I have seen of annular boosters they look like a rolled up airplane wing. It sounds like you did a good job with the 8 holes and a channel to hit all 8. Do you have any before and after pictures?

[@jimdouglasgregory]

Sidecardbob my email is [e-mail]. What engine are you working on?

[@jimdouglasgregory]

Sidecardbob I am in the states. I have heard of those motors before. Arnt they aluminum blocks?

[@dtruth5769]

Can the secondarys be partly closed under full throttle???

[@scaloi]

Why on my Eldelbrok on the main body cast it says Webber?

[@Poorboyzgarage447]

Because they baught out Webber carbs

[@robrozek9265]

Just bought a avs2 800 cfm carb how come the secondary side of the carburator does not have the annual boosters as well

[@Rafael5leyva]

for how many psi of fuel is designed...?is the same like the other regular edelbrock carbs 6.8 or so PSI?

[@Texassince1836]

Run the same fuel pressure as any other Carter AFB based carb.

[@ralphvalkenhoff2887]

Is a 650 for my mild 85 360 too big?

[@EdelbrockTV]

That's ideal.

[@car_ventures]

As the booster on a regular 140x can be removed to clean... Can an AVS 2 booster be switched into place?

[@edwardmcmillenjr8443]

Is this carb smog legal in calif.my chevy truck is a 82 chevy c30 with a quadrajet 350.its considered to be non egr non cat equipped truck due to its gvw 8600lbs.it has a smog pump.the rest of the smog equipment is thermal vacuumed controlled.the limits for hydrocarbons is 200 hcs or below.

[@stephenbacigalupo3970]

My 1406 on my pontiac 350 accelerator pump is shot carb is 25years old should I rebuild or is it worth rebuilding or just slap a new 650 electric choke carb on it can anybody help me decide thank u

[@robertpeters1497]

will this work with the edelbrock eps performance intake manifold, and what do I do with the valve cover breather that has the tip comming out the side code number 4413. dont know what the tip on the top side on the valve cover breather.

[@RaymondSigalaVideos]

what cfm do you recomend for a mild 305 on a c10 with a 700r4 and small 295/50r15 tires

[@ThomasShelby-uq8cz]

600cfm

[@SOLDOZER]

@@ThomasShelby-uq8cz AVS2 does not come in 600 you dummy.

[@lucius511]

I just put this on my car, & am experiencing that dead spot from idle to WOT ... after about a whole half second then it takes off.. otherwise besides that it feels smooth through the whole powerband.... what should I do ?

[@car_ventures]

Grab a tuning kit and change out the springs... Likely need to go up to a stronger spring. Also check which hole the throttle lever is set to... If it's in the top hole, move down to middle one. Try one at a time.. hopefully that solves it!

[@stevenbarefoot3976]

I have a 383 stroker and it just does not like this carb I can not get it to tune right it will go up and down in rpms if I'm in it not a smooth carb lol

[@DjTragik951]

Will this be ok on a 327 motor? I have the 1406

[@6.4hemidriver44]

Can the annular flow boosters from the new AVS2 be put on the older AVS carbs?

[@EdelbrockTV]

We will not be offering the Boosts separately.

[@6.4hemidriver44]

It's your company I guess.

[@19ADAM80]

Edelbrock USA Will the 650 be enough carb for a 450hp 355 engine?

[@Kalifero619]

Does the carb have to be tune if i have headers cam intake or just put the box is good

[@bobstephens8851]

Depends on how much duration your cam has. If it's nothing radical this carb should be fine out of the box. I plan on using the 650 avs2 on my 350 with aluminum heads, air gap intake, and cam with .504 lift.

[@gabrielbryant892]

[@peterc4961]

Not being able to retro fit all the previous Edelbrock carbs with annular boosters to cure an inherent flat spot problem is extremely poor business practice or most likely corporate greed. I will never purchase a new AVS2 to cure the flat spot issue!! To be clear, Edelbrock has lost me as a customer.

Garbage... the air door spring will break or unwind.. it's not a serviceable part.. Edelbrock will blame you breaking the spring.. their quality control is horrendous.. their tech line is worthless.... . But a 30 year old performer and clean it up.. performer is far superior.... it junk .. plain and simple

All that thing is is a fucken Big Flat spot floats were not set correctly metering Springs were Wong for normal engine I'm talking about a very mild Camed 9 to 1 Chevy small block 350With the air gap in take my favorite intake in the worldI bought one of these carbs because I knew and run of the Box and be reliable without a lot of tweaking m********** was I wrongI do put the biggest accelerator pumps quarter set the accelerator pump to the richest point give it as much time as I possibly could to get the stumble out of i tQuad jet would have ran betterHad great luck with these car racers before the new ones don't seem to have itReason you get a edlebach is because I don't wanna funk with a Holly

[@apimpnamedslickback6757]

Trying to put on of these in an f250 and it's the biggest pain in the ass I've ever had doing anything in my 30 years of working on cars. It doesn't clear hard fuel lines, it doesn't clear the unremovable bracket for the cruise on the other side without reengineering the throttle control. Garbage. If my girlfriend wasn't a total dumbass and believes everything AutoZone tells her, I would be taking this piece of shit back.

[@Mancavechannel]

It sounds like you're a shitty mechanic and a shitty boyfriend lol edelbrock carbs are great not the carbs fault it doesn't fit your truck

[@crautoguy8384]

F**** the old ones were way better take 3 days to get the stumble out of the mother funker I would rather just set up a Holly but the Edel Brock get better gas mileage in better response throttle response around town But the thing leans out when the secondaries open That secondary vacuum Plate with the holes in It bunch of junk the old ones of the solid plate I think work of better secondaries open up get up mass with the metering Springs Mild 350 horse 350 era gap 650 edlebach tuning nightmare Been doing this for 20 years plus never had so much trouble dialing in a carburetor Put super big accelerator Pump quarter and it Is much ported timing is I can give it Is more reliable than the single plane and the 750 Holley that I took off of it but it still has a off throttle hesitation All the research I've done on these new AVS carbs they seem to have the same issue everyone online is complaining about the same thing It's like the 650 is more like A750 Holly I've had better luck just put in a 600 on the thing Then they run out of the Box but these new ones they do not fuhkien run out of the Box Should have been easiest thing ever throw 650 on mild 350 Chevy have it run great That's why I Wanted to put edlebach on in Stead Of a fucken with the Holly Could a set Up the Holly to run perfect in half The time just would not have as good a gas mileage In less Street able Carb What the f***'s

[@JimBronson]

Bigger secondary jets maybe would help? I read these things don't have a 2nd accelerator pump.

[@Texassince1836]

Tighten the spring on the seccomdary air valve

[@Texassince1836]

@@JimBronson the only carb style with a seccondary accelerator pump is the Holley Double pumper (vac 2ndary holley are single pump) Air valve seccondary carbs (Like Rochestor or any AFB style carb) have no seccondary accelerator pump, but by slowing the air valve opening you can eliminate the stumble.
