IMMEDIATE RESULTS After Swapping Project Marsha to a Edelbrock AVS 2 Carburetor!

Mopar Connection's barn find project car, a '70 Plymouth Fury III convertible that we named "Marsha" hasn't been running right for a lot of reasons. We tried a basic rebuild of its factory Carter AFB carburetor, but rusty linkages seized up the secondaries and choked down the engine. So now we're doing a late-night upgrade to get Marsha back on the road while we tend to other repairs and updates.

The annular primary boosters really help the atomization of fuel for better manners in lower rpms I think. I run the AVS2 800 cfm on my street driven 69 Fury III 2 door on a mild 505 stroker and love it 3.23 rear and all. These big gals love the highway.

[@moparconnection]

Absolutely! Great comment!

[@mrtselfdefense4185]

That is an awesome old Plymouth. Our family, from Grandpa on down, have been Dodge-Plymouth folks since the 60s at least. I'd love to own that Fury droptop.

[@moparconnection]

Very cool!

[@tedslife7086]

After buying 4 different carbs this one was the best

[@moparconnection]

Glad to hear it

[@marc11467]

I'm running a 650CFM on my stock 440 and it runs awesome! Love the AVS 2!

[@moparconnection]

Awesome!

[@marc11467]

@@moparconnection I tried running the 800 CFM on it first. Car didn't like it at all. Maybe I could have tried using smaller jets. I did the calculation for CFM and it said 650 would be good up to 6000 rpm. Don't see myself exceeding that often if ever 🤣

[@moparconnection]

Perfect!

[@jackm.3666]

Love it Kevin! Outside in the dark like the old days! You are truly dedicated!

[@moparconnection]

LOL I had to get away from the kids!

[@peter455sd]

Yes,outside in the dark with the body aching after a hard days work. Because you are still young and love the game. Story of my life. How i miss those days.

[@moparconnection]

@@peter455sd the temperatures are starting to drop which makes laying on the cold ground just the worst - but hey! We got cars to build! Thank you for the great comment, Peter!

[@ericwilson2585]

Not sure if you're aware or not, but you want to make sure the distributor vacuum advance is hooked up to the port on carburetor that doesn't have vacuum at "hot" idle, but then gets a strong vacuum signal "as soon" as the throttle just begins to open. I.E., going into a port that is drilled in the throat of the carburetor that is just above the throttle blade/butterfly, when the throttle is completely closed and sitting right on the "hot" throttle stop screw, and "NOT" sitting on the cold choke, "high idle"... That way when the engine is completely warmed up, and as soon as you touch the accelerator pedal, the vacuum advance comes in giving you a really good throttle response, and keeping the spark plug nice and clean.

[@moparconnection]

Great comment! And yes, the vacuum advance is connected to the correct port.

[@ericwilson2585]

@@moparconnection OK gotcha. Well if anyone watching wasn't aware of this, now they'll know. I was wondering because for some reason it took me quite a while to figure that one out, lol.

[@moparconnection]

Absolutely! Incredibly helpful (and detailed) explanation!

[@alyarmak-bu8it]

Those are great carbs, i put a avs 2 650 on my 69 fury III with 383 ans i absolutely love it.

[@moparconnection]

Very cool!

[@dwayneventon]

Love it on my 383 I have tried 5 carbs and this is the best by far 650 cfm.

[@moparconnection]

It's almost always a winner!

[@rogercann7210]

Nice work, only a 318 down on 2 cylinders can run nice with a 4 barrel carb! Love your channel as it has feal life work in your driveway.

[@moparconnection]

No high ceilings, car lifts or fancy shops here! All jackstands and hand tools!

[@lukepokrajac1057]

AVS 2 650 is an AWESOME carburetor on my 68 sport fury HP 383. Almost as good as fuel injection.

[@moparconnection]

That's awesome!

[@noampitlik2332]

Really good carburetor.

[@moparconnection]

It sure is!

[@cbobmonster]

Just bought myself an AVS two for my 75D 100 waiting for the adapter of course

[@moparconnection]

Very cool! Let us know how it works out!

[@firebossbob]

Ran into you at the Moparty this year, didn't talk but a minute. my wife and I have the 1966 Dodge Dart GT convertible.

[@moparconnection]

That's awesome! I'm sorry I was running around the whole weekend. Glad we could chat - even for a brief minute!

[@gimmesomesugar]

Night time is the right time........ for installing a new codjulator.

[@moparconnection]

LOL it’s a little less than ideal

[@belloa3026]

Where do you connect the electric choke to?

[@moparconnection]

It’s mechanical

[@richardleser6505]

Excellent!!!!

[@moparconnection]

Appreciated!

[@icetech6]

so 6 months later, how has the AVS2 held up? Trying to decide on a carb right now and am looking hard a the 800cfm avs2

[@moparconnection]

Literally 2 pumps of the pedal and she fires and idles every time. I’m super happy with it.

[@jantienesstruyk3538]

What size carb did you put an de car

[@moparconnection]

650cfm

[@Vntichrist]

Hope this solves my problem, hope you’re doing good as well brother

[@moparconnection]

The 318’s still hurt but at least we can still move Marsha around.

[@stuntmanmike7777]

Good job! What kind of spacer did you use?

[@moparconnection]

Holley's (Quick Fuel) 4150/4160 Flange Gasket - PT# 8-108QFT

[@stickxxcummings]

Nice job

[@moparconnection]

Thanks!

[@Trex1268]

Does the stock bi-metal choke spring work with this carb? I wish you would have shown more close-ups.

[@moparconnection]

The stock choke spring does work, you need to bend the arm a little wonky to fit it.

[@Cuda_Jim]

I’m looking to get one for my 70 Cuda, so just to be clear you used the manual choke model and was able to connect the stock divorced choke to where the cable is supposed to connect?

[@billward4418]

How do you like your avs 2 Considering a avs 2 for my 318 500 cfm.

[@moparconnection]

Absolutely a major upgrade from the Carter

[@boydsdodge]

Fender covers? Electric choke?

[@moparconnection]

Mechanical choke, and no, no fender covers (I probably should've but this poor thing's a golf ball). And how much do you want for your TB Imperial? I just checked out your page! That thing looks RAD!

[@boydsdodge]

@@moparconnection Ha Ha on golf ball. I know I have to sell TB, but I am having a hard time pushing the button on sale. Did you see the long winded video from picking it up to today?

[@moparconnection]

I'm watching it now. I know I can't pay you what it's worth so I hope you find a good home for her. (But I am curious what a car of that caliber goes for.)

[@citizen2162]

I used the 800 cfm on my 440 , just can’t get the secondaries to open right . Running rich .

[@moparconnection]

Hmm. Yeah, sounds like it wasn't dialed in for your combo.

[@SpeakerKevin]

@Citizen Check the float heights.

[@moparconnection]

Yup!

[@belloa3026]

Will it work on Chrysler 400 engine?

[@moparconnection]

Of course it would

[@belloa3026]

Don't you need a adapter plate?​@@moparconnection

[@misaelmedinacarburacion]

✌🏾✌🏾✌🏾✌🏾

[@moparconnection]

👍🏻

[@jimgee2676]

did that 318 start life with a 4 barril ?

[@moparconnection]

No sir. It received a '69 intake and Carter AVS from a Dart sometime in the mid-1970s.

[@glennmanchester5696]

They are essentially the exact same as Carter was bought by Edelbrock and nothing really changed just the name they originally were a Carter AFB then morphed into Edelbrock carbs which work fairly well in the 80s Chrysler actually uses quadrajet carbs which are even better than Edelbrock carbs

[@moparconnection]

At the beginning, yes. Edelbrock made a succession of upgrades, changes and improvements over the years. The AVS 2 is sufficiently different from our AFB to make a difference.

[@tomdamon7208]

what a hack !

[@moparconnection]

How so?

[@Lola-co8jg]

Awwwwe c'mon !!!!

[@sjl9942]

Bet she either had no job or works part time for peanuts and bro is the bread winner and she calls him a financial burden, shes just mad hes not spending it on her and her dumb project ideas.

[@moparconnection]

Huh?

[@user-ym8pd9kj4k]

Too many people buy the Edelbrocks for the wrong reason-they are so shiny. A well tuned early Thermoquad is 10 times better carb than the shiny Edelbrocks.

[@moparconnection]

I wouldn't say "better" but I would agree that it's enough for most people's needs. Unfortunately, the Thermoquad is very limited in its fine tuning abilities and as Steve Dulcich says, punishes you for making horsepower. The Edelbrock AVS2 is far superior in tunability and responsiveness, especially for warmed-up engines.
