AVS CARB or Holley or CARTER ? on 440hp+?

[drives mopars]

my 440 needs a better carb i dont tune them much, have 4500lb car ,now has no top end
stock carb drilled jets up 1 size,
for 1/4 mile once a year , some car shows, is the new 750 carters a lot better
and will they give me that top end i do not have now, now feels like not enough fuel
in 3 rd gear in 727 at the strip. i dont want to play with the jets much or the rods much . i dont like test and tune ways much
i know its best that way, iam just not good at it.

Personally I like the Carter better. I have them on all my small blocks. And have run them on many 440s. If you state what your running when you order the carb,it will come set for the engine running(A little on the rich side). They have given me many miles of trouble free driving. For an extra 50 bucks they will sell you a strip kit with an assortment of jets,rods,and gaskets for fine tuneing.

Has anyone tried the newer 'Demon' series carbs. Basicly a reworked Holley. Supposed to be real easy to adjust and fine tune it to your particluar application. Prices are more reasonable than Barry Grant.

Some guys swear by Barry Grant carbs. I have not seen them advertised lately. They were not cheap either.

Buy the Edelbrock carb, it is a refined carter. Buy the tuning kit with it when you get it. All of the adjustments can be made without spilling fuel or taking it apart. I have never seen a carb that is easier to adjust, and they work great.

Holley has the best set up IMO. YOu get tons of pump shot, tons of trick parts available also if you want them. Only expierence I have with Carter/Edelbrock i taking them off lol. Don't let the power valve blowout problem people talk about scare you unless your car is tuned so bad it pops through the carb on a regular basis. I have been drag racing the same carb for 6 years now and it has not been rebuilt and has had only 2 power valve changes for tuning reasons.
The Demom series cars look COOL but they seem to be a love hate type deal with racers. The Demon is the same as BGs Claw series i believe not sure though. Good luck with your choice.

Has anyone seen the recent Mopar Muscle 440 build up? They took a '69 440HP and did a basic recon- all back to stock. Correct pistons, heads (906),Mopar resto cam, intake and exhaust manifolds and mopar electronic ignition (what was available). Then they did dyno pulls, first stock (350HP), then with basic mods one at a time. Very good article. Biggest boost per $ was headers, that was after they put on a 850 Vac sec. Holley. I run a 12 sec. 340 and had a street 440, I use 750 vac. sec. Holleys (3310) on both. Fantastic carb once you get the jetting and secondary spring right for your engine.

Your best advice is at the Mopar guys in Indiana. They will tell you exactly what works best, even tell you how to tune it. For my money, the Holley is a best buy; more adjustable and easier to work on.

I would never use any carb other than a Carter on my mopars. I have found the AFB to be a most excellent running carb. It does, however, require that the tuner have some vague idea of how carbs work, to get anywhere tuning it. I use a 625 AFB on a slant six, and it actually runs good, and gets 20 mpg on the highway, in a D150.

The CARTER strip kit is best, as it contains a wide variety of good parts. Between the jet, rod, spring and accelerator pump nozzle selections, there's almost nothing you can't make work, and work quite well.

But, as I said, you do need to understand the theory of how carbs work in order to get anywhere tuning it. Tuning includes jets, float level, springs, metering rods, and so on.

I have a carter strip kit. Never used. First $25. 00 and it's out the door.

I always ran Carters or Edelbrocks on both my Mopars,one a big block and one a smallblock. Had great luck with them on the street. However if you want to go as fast as possible for your set up, I'd put on a double pumper Holly. Droped my 8th mile ETs 4 tenths with no other changes. Even I was impressed. They both will work well though, but a little tuning on the Carter may be worth while. Bottom line street,Carter,Strip Holley. Good Luck.

Ok I can hear you all laughing now, but in a 4500# car a Thermoquad would work great. This guy doen't want to do too much tuning.
with the small primarys the bottom end response is great. But when the vaccum operated secondarys (which are adjustable) open BWHAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
Sorry just a flash back to my first car, 76 Cordoba 400 4bbl.
But seriously the small primary/big secondary thing will work better in this application IMO

Just put a coffee can on it. There's a Holley on everything we have in the garage except for my 32 Ford which has 4 Rochester 2G's on a Man-A-Fre intake. Talk about a pain to dial in.

 

[Bad340fish]

The thermoquad is a good carb but you gotta do all kinds of wierd sh*t to make them work on a modified motor. My dad used to run 10. 80s on a full race thermoquad. Had reverse metering rods and some other odd things. It didn't start that well and was inconsistant. Changed over to a holley 750 dobule pumper and the car didn't speed up or slow down but was more consistant, alot more. Started better and required ALOT less messing with. Walk around the pits at the drags... do a carb count base you decision off of that.

[drives mopars]

thanks, all u guys,

i did read the 440 mag art i may
plan to get that carb and especially the intake, have magnum manafolds now.

i have a carter and strip kit
but never used it, carb is vg cond
but was used some, i really dont want to
mess with this carb. i really want
to bolt on a carb thats a lot better the the 69 AVS , and also plan to upgrade the fuel line ( bigger) to the new mech pump.
also bigger,

compared to the holly i priced the 850
in the mopar rag its was about 450-500
i think thats more that a 750 demon

have any of ya tried DEMON carb
yet?
also do any of you have Expr ww/ the AVS carb, upgradeing it ect. the mopar rag
says on 440 stock a 850 added 10 hp
my AVS 2 years ago was running real lein

Sold my Holley and went with a Edelbrock, never regretted it.
Remember, Ford was big on Holleys!
Also had a Q-jet worked over once and it worked great.
But I always loved the Edelbrock kick.
Isn't the Edelbrock bacically a copy of the AFB?

[Jeff Clark]

No doubt Holley's are tempermental on an everyday driver. I've had the same Holley on my 69 Camaro for nearly 10 years ( I bought the car when I was 14) and haven't touched it once. No adjustments. The car starts fine every time.

 

[Bad340fish]

I somewhat agree on the Holley drivability. Mine was a daily driver when it broke into the 11s(11. 993 lol) This car was a daily driver for a little over two years with a holley, ported heads, 999 trans with 8" 3800 stall. Gas bill was hard on the wallet.

I had a 67 Cuda with a midly bombed 273 in it. It has an Edelbrock on it when I got it and it got around 14-15mpg with my lead foot. Put the holley off of my 340 car on it and the mileage went to crap but it started better and ran ALOT better even though it was tuned way to rich for the 273. And then i tried the AVS that originaly came on my 340 car. It was the hardest to start cold idled well, got 17MPG with my lead foot. It also ran just as good as the holley WOT. Fooled with air valve for hours trying to tune a stomp throttle hesitation out of it. Then I sold it to TDR member Hiperf 360 and he succesfully screwed all of my tuning(i put the edelbrock on it again) and killed the mileage LOL. Long enough post?

In retrospect, are you SURE you're getting enough gas into it?

You can get oversize float needle/seat combos that will flow a lot more gas into the carb and maintain a more stable float level.

This lack of top-end just sounds like low fuel flow. My 440 would run smooth, and continue to, even if you leaned it to the point of having no power, as long as the engine was loaded and running fast.
Just thinking out loud... #ad
