What carb for 440

[Napoleon1991]

A properly tuned Q-Jet will run as smooth and accelerate as fast as any other piece on the market. Check your plugs, wires, cap etc for problems. Make triple sure there are no vacuum leaks. Don't be real quick to blame the carb for a bad idle.
Someone a lot smarter than me once said, 95 % of all carburetor problems are in the ignition.

And ,by the way, Mary Ann all day long and twice on Sunday.

Yeah, I know it properly built Qjet is hard to beat. Have one on my 69 Cutlass and it’s amazing. I do know that this one has a lot of issues though. After disassembly, it’s obvious that someone was messing around inside of this thing before. There definitely appears to be mismatched parts inside of it after a close inspection. Turning in the mixture screws all the way should kill the motor, but it keeps on running. It surges quite a bit at idle after it warms up. It runs decently at part throttle but doesn’t have that almost fuel injection feel of my other Quadrajet.

I would consider a 800cfm avs2. EDL 1913
It is the only edelbrock that I would consider.

Just started looking into this one after you mentioned it. Is it fairly simple to tune?

I figured everyone would have a different opinion lol.

Of course....everyone has different driving styles and combinations....heck, just about each car when produced new liked a different tune. A lot of it depended on the tolerance of the parts when produced and is one of the reasons I always preached to degree in the cam no matter how mild it was. Using the dot method is pretty much a dart game.

Air is air and gas is gas.

Even that depends on where you live lol

Yes, it is affordable, easy to adjust..and if you research it you wont find much (if any)complaints on a application like yours. The Motor trend article has all the info you likely need to tune it.
It is a good "bolt it on carb and go" that isnt going to take much dialing in. For what your doing I prefer the avs2 over any Holley vac secondary. All the holleys I have run needed some additional part to change out to get it to perform the way I wanted. I am still waiting for a holley to work perfectly out of the box. But the good part of a holley is you can fiddle with it. If you had a bigger cam and it was more competition oriented. I would run a holley.

The only reason that I'm partial to the AVS2 Edelbrocks is because they're so darned easy to tune.
You can do everything from the top without spilling fuel all over the intake, and the complete jet
kit is about $80.00. 750cfm for cruising and 800cfm for "Mashing" it as was stated before! Merry Christmas!

Yeah, I don’t trust the dot method either. I definitely degreed the can before buttoning it all up.

Yeah bolt on and go is pretty much what I’m looking for. I don’t mind some tuning, but I don’t wanna dick around with it too much. The car isn’t raced at all, it’s just a cruiser so I’m looking for something simple and reliable that will still perform well when I decide to mash the skinny pedal.

Merry Christmas to you too! You guys definitely got me leaning toward the AVS2. Would the 800cfm still be responsive at low to mid throttle?

Just a cruiser.....? Big carb isn't needed at all then.

Never used one before but don't see why it wouldn't be responsive at low to mid throttle. The hi po TQ worked well and it was rated at 850 iirc.

 

[Curiousyellow71]

You have enough motor I think it would be very responsive. It is what that carb is known for.
Merry Christmas!

I realize I’m going to get a ton of different answers with this one, but im looking for some suggestions on what type of carb to go with. Engine is a 440, 10:1 compression with a voodoo 703 cam. It has TTI headers, a performer intake, 727 transmission and 355 gears. It has a reman Quadrajet on it right now and im tired of messing with it trying to get it idling smoothly. I’m leaning towards Holly or quick fuel, definitely something with vacuum secondaries. Any help pointing out the pros or cons of different carbs or what CFM size I need would be appreciated.

A Holley model 4150 R-3310-1 (yes, they are still available a little pricey), 780 CFM, vacuum secondary and down leg secondary booster venturii operation, and when dialed in to your engine and application will provide great throttle response and top end power. Parts readidly available. Equipped with a hot air choke, convertible to electtic choke or manual choke using a cable. The R-3310-1 IS NOT THE SAME AS THE R-3310-2 or -3 or the varients (750 CFM), which are the model 4160 design (secondary metering plates). OR.... if you prefer an OEM AN OTIGIONAL CARTER AVS......NOT AN EDELBROCK (aka "Eddy" to the uneducated) AVS2 design, which only resembles the AVS design.....ive used the Holley 4150/R3310-1 with a Torquer II and similar engine parameters with great success......just my opinion of course.....

An 'Eddy' intake or carb is the short version or 'slang' if you will.....education has nothing to do with it.

I guess, using the same vane, a "Dizzy" is used interchangeable with the correct terminology for a DISTRIBUTOR.....I guess society prefers slang terminology vs the real word.....although not sure why....perhaps it's laziness or maybe the person using the term just not know how to spell ?.....something to think about.....

[The Capitan]

What about a Elderbrock?

Well, don't know about anyone else but, I know how to speeel

Ah, yes the Holley vac carb. Didn't do to well against a 625 AFB [ see below ]. Made less tq, less hp & used more fuel....

Over on FABO, you will see a thread where a Poly Stroker engine had a 600 vac sec Holley removed & replaced with a Edel AVS2. When the owner went for a test drive with the AVS & went to WOT, he thought the trans had kicked down to 2nd such was the acceleration improvement. But no, still in high gear....The smelly was also gone....

 

[RemCharger]

The holley 600 was considered a performance carb by no one.
If people have to dyno against it to try to feel good, I say good on them.
It's part of feeling special .
Have a special Christmas.
