Looks like a 4160. Good carb and good price. Summit lists it new for $275.95.

I run a 670 Holley Street Avenger on my Dart and love it. Pretty stock 340.

A nice Holley at a good price is a good ide.

I guess that would depend on your intended usage for the car. Is it a cruiser? Do you plan on taking it to the strip? Is it going to be a dual purpose machine? These are all things you need to consider.

If it's just going to be a cruiser with an occasional trip to the track, you might want to go with an Edelbrock Performer Carb to match your intake. They are pretty reliable carbs for all-around driving and are pretty easy to tune.

The EDL 1406 would be my choice.

That carb is a little small for your motor but if it's a daily driver and you're concerned about fuel mileage then it's perfect. But if you're looking for performance at the expense of gas mileage you'll want something a tad bigger.

Yup, on the small side. I like the carbs with the center hung floats like the double pumpers use. 3310 vacuum secondary carbs use the same type of bowl and use to come in 780 cfm and now in 750...not sure of other cfm sizes.

I personally do not like Holley carbs, probably due to bad experiences with them in the late '60's-early '70's stock Mopars. That said, I would stay away from anything that said "rebuilt" or "factory remanufactured".

Many years of experience with rebuilt parts has taught me to either: A. Fix it myself, or B. Buy NEW! Many times even NEW carburetors need to be checked for proper float levels and linkage adjustments before using!

If your Eddy Performer manifold has a spread bore configuration, I would try to find a good Thermoquad (or NOS), and rebuild it myself; if it is squarebore, then buy a NEW Eddy 1406 as Cuda said! The Thermoquad will give better mileage and low end driveability than the Eddy, in my opinion, due to the smaller primaries, and huge secondaries!;)

I remember the factory stock Holleys being troublesome too and I also like the TQ. IMO and experience, A Holley usually requires more maintenance and tuning. While the TQ will keep a tune longer, they can be a bear if you don't know how to tune one. I remember the TQ being even more of a pita than Holleys on factory stock Mopars and the stock AVS's etc didn't seem to offer a decent amount of performance. The Holley carbs that I've had the best results with were all double pumpers. In town gas mileage generally sucks with them but can be pretty good out on the highway IF you have a steady foot. If you set them up for max performance, forget about decent highway mileage too. Can't give you much info on the present day carbs from Edelbrock because I haven't had any experience with them....but others seem to like them. So far, the best street carb I've ever had was a TQ on a 71 340 Cuda. Real decent in town mileage and it performed very good but it took me awhile to figure it out after a rebuild. A tool that no TQ tuner should be without is the one that allows easy adjustment of the secondary air door (looks like a choke plate on the back barrels). The adjustment can be done without it but having it makes things a LOT easier.

Amen to the comments on the TQ incl the one about that tool. I just wish I could find a TQ, with an integral electric choke!

I agree with Cranky on the Thermoquad....they rock! In stock Mopar form, there were a couple of problems that cropped up with them over the years, like sunken plastic floats (brass are available, and were in the early carbs!), the O-rings in the bowl under the top air horn, and the early base gaskets, but once they were set up properly, they couldn't be beat!! The biggest problem with them is that nobody takes the time to make ALL of the tons of linkage adjustments in the proper order....each adjustment depends on the previous adjustment being CORRECT!! Most of the problems associated with Thermoquads are due to "technician error". The carbs are great!;)

I have had Thermoquads on my daily drivers for over 30 years, and almost NEVER had to touch them, except a yearly choke and linkage spraydown!:)

I once bought a '76 Cordoba from the original owner for $100. because nobody could fix the stalling problem when it was warmed up. I put a new set of floats in it, and drove it for over 4 years, got over 18 mpg with the 400 leanburn, and only retired it when the rear springs came through the floor of the trunk!:rolleyes::eek:

The Tquad tool is a handy thing, too, but it isn't all that hard to adjust the air valve without it!;)

Jenkins, what number Tquad do you have?....maybe you have a large primary carb for a 440, or a competition series, that might be too large for your engine/cam combo. Does your manifold have a spreadbore design?? You may need the proper adapter plate for it, if it is squarebore!

Thermoquads were used for a number of years on even 318 police engines with good results. They are very forgiving for cfm size, as they are an air valve design, that supplies based on what the engine requires, not what it is rated at for full flow.

i got a Tquad from DemonSizzler (you've probably heard of him) All the choke hardware was removed, and the tower sawed off so its beyond repair. Thats a big part of me wanting a different carb. And yes my manifold is spreadbore!!!

I don't know why no ones mentioned this, but it says "factory remanufactured" I wouldn't touch it w/ a ten foot pole, no matter what your carb preference. Buy one new or from someone you trust. Like I said maybe I'm wrong, but I dont know the ppl so I wouldn't trust it. = 2 cents

Yup I HAVE to agree on the Reman deal unless you get it cheap enuf to get it RE-gone thru by someone that you know, who KNOWS what they are doing with it!!

Dietz, if you go back in the thread, I believe I mentioned to NOT get a "reman"....do it yourself! Remans are usually nothing but problems, and not just carbs....that goes for just about anything, such as alternators, starters, water pumps....the list goes on and on!!!!!!;)

Jenkins, I remember that you posted about this before, about the carb having no choke tower. This must have been a full race version of the Tquad that DemonSizzler offered, and, if so, you are probably WAY
overcarbed!!


---------------------------------------

http://www.thermoquads.com/ (http://www.thermoquads.com/)

Full Race build

includes:

everything from Street/Strip build plus


machine milled front and sides of the choke tower for max performance,
2ndary throttle lock-out shaft removed for 75 cfm gain,
remove-able bleed system,
2ndary shaft lock-out system removed for all-time 2ndary action.
Optional work:

top plate glass beading........................................... ...........$45

slab primary and 2ndary shafts............................................ $65

-------------------------------


There is no reason a Thermoquad would not work in your application, especially since you have the spreadbore pattern; the only possible scenario is that the manifold will not accept the stock choke spring/heater unit, as on the later 318 4bbl police manifolds from Mopar that used the Quadrajet! I ran into that on a '88 Diplomat 318 that I ended up using an Edelbrock electric choke #1406 on, because I couldn't find a recessed choke heater that fit the manifold!

I would recommend a small primary Tquad for better fuel economy and low speed throttle response. I might have a couple, if you are interested, including a NOS '72 340 4spd carb, or possibly a nice later model truck 360 carb. Let me know!;)

I saw an NOS low-cfm (like 600) T-quad for $450 from some "carb shop . com" or something... I'm probably getting a Summit brand carb. (It's a Holley with all the features I'm after, just cheaper and lower cfm, great for a stock cam 318)

DO NOT worry about the cfm rating on a Thermoquad...they are very adaptable, and were used on factory 318, 360, 400, and 440's. I don't believe Carter even knew the cfm rating....they just said whatever anyone wanted to hear!;) There are basically only two Tquads, a small and a large primary version (1 3/8" and 1 1/2" primaries). Some aftermarket Tquads were offered in the Competition Series, up to 1000 cfm or so....but you do NOT want these for the street!

Don, the 9801S and 9811S Thermoquads were factory aftermarket replacements made for Mopar vehicles, with the proper linkage setup, and an integral electric choke to supplement the age-old problem of Mopars with the broken heat risers, and plugged crossovers in the intake manifold!

They are out there, and many were sold....you just need to know what you are looking for!;)

I would never use a "factory reman or rebuilt" unit, unless I took it apart and checked EVERYTHING myself...........the only problem is, you DO NOT KNOW if all the parts in there are the same parts that came from the factory when new! Rebuilders throw everything in a bin, and pull parts out at random, not even knowing if they are compatible.:mad: There are so many possibilities that it is mind boggling!:rolleyes:
