help me find a carb

[1978cordoba]

OK so i need some guidance on what carb i can use on my Cordoba, i have a 78 Chrysler Cordoba with a 360 and a 2 barrel carborator right now and i want to upgrade to a 4 barrel carb, but i dont know what i should be looking for. so if you guys can help me with getting a 4 barrel carb and an intake manifold, im thinking about looking for some when i go to swap meets and such

thanks a lot

Cant go wrong with a Edelbrock Performer manifold, and a performer series carb, 600 or 750, for a stock/mild 360.
Try for the 600, unless more upgrades are coming later.


Now Rumbles turn..........

An OE iron unit will be cheapest. Find one without an EGR.
The T-Q model and a T-Q carb will be the best at making HP and drivablitiy.
If you get a sqaurebore carb, a 600 will do fine, no larger than a 750.

I'd leave the Edelbrock Performer on the table myself since the stock iron intake will make better power and is all ready port matched.

Other intakes are a unknown to me personally if they will fit under the hood of the car.

Your aircleaner will be limited in size. But a nice factory unit from '73-ish is a great trick peice. It has a single snorkle and a trap door in the base. It opens with a lack of vacuum and allows air from outside to rush in. FYI, K&N has replacement stock sized air filters for MoPar 4bbl. aircleaners.

I spaced the iron manifold.......... I always get toppled over putting them on, LOL, heavy suckers......
You know, I know it is taboo, but a big port Offey Dual Port is a neat one.........

If you lived in AK....... I'd give you three stockers, I have tons.

[Cudafever]

I would go with the stock iron manifold and TQ(if you can find a good on) my self too!

One more thing to consider here, is the kick down linkage............Your 2 barrel linkage won't work................Its the solid rod type kick down lever.... right?

so if you can find that manifold and carb in the junk yard........grab all the kick down linkage as well!

[TK]

The 2bbl linkage, is longer..... Right?

I have shortened them and welded them the proper length. Not bad to do, but damn, you cant cut them w a hacksaw! LOL

[Cudafever]

I can't remember for sure, but in theory, the 2 barrel would be centered in the manifold and the the 4 Barrel would have the lever on the front barrels

Making the 2 barrel linkage too short

[TK]

* Scratching head, and looking at a couple trucks in the yard*

My 74 318, was a 2bble, now has a streemaster, and a Edelbrock.

Didn't mod the linkage at all.............. (Just used the Mopar kick down adaptor kit)
The 69D200

Rod was too long, cut it, and used no adaptor.

Either way, a bit of figgerin' and it's pretty easy, and we have pics we can post to help.

[Cudafever]

Yeah us to have a big box of kick down rod brackets and pivots to mix and match when i would go from a TQ to a AFB, to get my kick down to work right.

My Holley carb don't need it as my manual shift Valve body(727) fix all that grief!

If you can't find a good Thermoquad , and Demon Sizzler is a good man to ask about Thermoquads , then when you look at the Edelbrock Performer series carbs , take a look at the Thunder Series AVS . I bought one last year late in the season , and I like it better than Performers I have used , and even better than my old Carter 625 Competion Series I once had , and that was a very good carb .

Factory 340/360 4bbl spreadbore intake w/ a TQ carb would be good, or any squarebore dual plane intake w/ 340/360 sized ports & a 600-750 cfm carb, either Edelbrock/Carter or Holley vac. secondary.

so the 340 and 360 intake manifolds are basically the same?

also would i be able to use any of the "600-750 cfm carb, either Edelbrock/Carter or Holley vac. secondary" with the "Factory 340/360 4bbl spreadbore intake" (in case i cant find a good TQ?)

No, there exactly the same. The only difference in intake manifolds is the year there made. Some are squarebore intakes and others are spreadbore. Most spreadbore intakes have EGR valves. Just bolt up the EGR valve and leave disconnected.

Yes.

Yes.

This is probably the best induction set up for a stock or near stock engine. The iron intakes, although heavy, are very good pieces. The 340/360 4bbl spreadbore intake will be easy & cheap to score, and if you decide to run a squarebore carb such as a Holley or AFB/AVS, all you'll need is a $10.00 adapter to bolt it up. On this site, there's a good page on Thermoquad carbs with application part #'s if you decide to go that route. Checking out Demonsizzler's website will also be helpful. Good Luck!

so i went to the swap meet today in englishtown NJ in hope to find an intake and possibly a carb. i could not find a good one, every person i went up to with intakes i would ask what there for and they all had small block chevy intakes. so i guess i will have to wait for the chrysler nats at carlisle. but i did score a pair of headers for $35...

how do i tell apart the squarebore and spreadbore intakes?

If it would work, I have a 750 Speed Demon I took of my 360 Cuda. Thanks.

The holes for the carb secondaries on the intake flange are much larger than for the primaries. In other words, if you look at the intake from the front as it would be installed on the engine, the front holes of the carb mounting flange will be smaller than the rear.

HUH? Your new to this? I had know idea. The difference is in the wording. A squarebore intake has a square where you mount the carb. The inlet looks like this;
oo
oo

A speadbore intake has smaller front inlets and larger rear inlets for the carb. They look something like these O's or like this;
. oo
.O O

Not all intakes have holes. Some will just have wide open areas in the described shape.

First picture, stock spreadbore intake designed for T-Q's. (Thermo Quad)
Second picture, A Edelbrock TorkerII a squarebore intake.
Third picture, A modified intake from a divided plenum (Area under the carb) to an open plenum, this intake was cast as a sqyarebore intake but was modified to accept a spreadbore carb.

Read up here on intakes by a smart guy that can explain a few more things; http://victorylibrary.com/mopar/intake-tech-c.htm

[rumblefish360]

Heres a few carbs. (The first 2) These AFB/AVS are squarebore carbs, most Holleys are also a squarebore.

The next one is a T-Q (Thermo Quad) carb and is a spreadbore carb. The secondaries are large, about 2 2 -1/4 inch. I forget.

[dave5711]

Weiand action plus manifold and a thermoquad!

[dave5711]

Sorry, that was an inside gag for the guys who have been on the board for a few years...

In all seriousness, a nice little dual plain alum intake(whatever one you like) with a small four barrel, depending on the combo.

A nice 650 vac secondary holley, or eddy of similiar displacement rating.

A 750 demon is likely not a good pick for a 2 bbl 360, turned into a 4 bbl. Demons flow more than thier ratings. I recently replaced the 750 mighty demon on my 440 with a 950 hp holley worked over by a very reputable carb guy.

No real measurable improvement in et.

FWIW, I only run a 625 road demon on my 440 motor home
