I have a '72 stock 200hp 350 modified with 9.5:1 pistons, heads opened up to 2" intakes, mild cam, headers, 3" exhaust and have an Edelbrock 2101 Performer manifold. Engine should be @ 350hp, if I put on the right carb and get it running acceptably. My dilemma is that I have had 4 rebuilt carbs and swimming in dismal failure. I thought the Qjet that was on the car was the original and tried to have it rebuilt, but was unsuccessful. Temporarily I have an old AFB Electric Choke carb on it and running pretty well. Here is my question. I want a "new" Qjet. In other words, I'm looking for a carb that will bolt on to the performer manifold, use existing linkage, fit under the hood with stock air cleaner, not require any modifications, have the right vacuum ports, provide reasonable fuel economy and performance. I just want it to hook up just like the qjet. Most important is start good, idle good, run good...not performance in the 1/4 mile. Please don't respond with "keep working on your qjet". But do answer if there is another carrb that i've missed that hooks up perfectly and you recommend. I've dumped too much time and $$ into this effort. I'm honked off at my mechanic and the whole carb restoration process, so just want to get a new carb, a new mechanic and start fresh. I know everyone has "preferences", but I want to specifically know if the Edelbrock Performer Carbs do what I mention above. It looks like the 1406 600cfm electric choke is what i probably should buy? Thanks and sorry for the long post !!

 

The 1406 is a square bore
A Quadret is a spread bore, so my answer is no.

 

i have a 79 vette with a edelbrock dual plane intake on it with the edelbrock 600 cfm 1406 carb and it works great and bolted right up. also you can buy metering rods to allow for more fuel that pop right into the top of the carb just from unscrewing a screw

 

Since you have the Edelbrock 2101 manifold the Edelbrock 1406 should bolt on. I have the same manifold, and it is machined to accept a Q-jet and Carter AFB (Edelbrock 1406). I had the 1406 on my 78' for a couple years and it was trouble free. Starts easy and runs well. Had my original Qjet "restored" and it has more power than the 1406, but doesn't start as easy, but I'm no carb tuning expert. Here's what their web site has to say:

Yes, the 1400 series will fit the Performer Intake fine but I got the impression that 72 Ttop was looking for a Quadrat replacement.
Thats why I replied with a no

Since the engine isnt stock do you guys think the 600 CFM will be enough?
I believe theres a 1407 as well

 

Bob, by replacement, i mean the closest thing i can get that will fit, bolt on, without mods, and meet the same kinds of specs the qjet did. ie; good performance and good around town driving. I'm looking for the sam all around performance that the qjet was famous for without the 30 years of wear and tear. And curious if everyone thinks the 600 is ok, or if I NEED the 750...what happens if you put on one that is too big?

 

From all I have read the 1400 series is a good carb but theres a big difference between the Edelbrock 1400 series and the QJet

Im sure the Edelbrock will serve you fine if you want a dependable carb that has good performance
As far as the 600 vs 700 cfm, I dont know the answer..sorry

 

600 is the right size for you esp. if auto. trans. Holley makes a direct Q-J replacement about 650 which would be fine- 4175 available w/ vacuum or mechanical secondaries,

 

I have an edelbrock 650 thunder AVS for about 6 months now and it has worked great. I have performer EPS mainifold.

2 months old, $175 and your good to go. #1406 w/elec choke, see pics.

If you use the Edelbrock AFB, you will need a new throttle cable bracket as the stock Qjet one won't fit the bolt pattern of the Edel.

 

I know you don't want to hear this, but I have to say it. Your problem isn't the q-jet, it's who you have working on it! You are throwing the baby out with the bath water. I have had Holleys, Edelbrocks and Rochesters and the Q-JET is far and away the best. Get rid of the idiot, not the Quadrajet! God bless, Sensei

 

This is all you need, Summit has them for around $25. It works for the detent cable & throttle cable.


#EDL-8030

 

but diddnt want to say it as 72 Ttop diddnt want to hear it

4 rebuilt QJ's and no positive outcome?
I'm guessing they were Comercially rebuilt units which are essentialy garbage
Or... one rebuilder that has now idea how to rebuild a Qjet....

 

so, Bob, what is the big difference between the Edelbrock and the Qjet?? what does the Edel not do that the Qjet does?
And Ganey, when you say Holley makes a DIRECT replacement, what does that mean, bolt on and go or redo linkage and vacuum hoses and?
and Sensei...oh, you are sooooo right...I know it is not the carb and I have not had 4 Qjets rebuilt, just one..twice. The problem is that I sent the Qjet to be built by the most reliable person on this forum and when it came back my mechanic could not make it work...so I was (once again) stuck in the middle and screwed...
so my belief and someone PLEASE tell me if I'm wrong, is that I should be able to buy a carb (whatever model) that functions basically the same as the Qjet and has good performance, good gas mileage, starts easy, fits correctly, and doesn't need "tinkering" with all the time.
The local corvette shop, who I have basically lost faith in, could not get my Qjet rebuilt, so I sent it away to a pro. When it came back, they could still not make it run acceptably... in the meantime, they had an Edelbrock something, rebuilt, and it ran like crap, and then they put on a new Holley (don't know the model, and it developed a host of problems, including stuck accel pump and gas leak, and it was NEW (they said)...? Having a car that was leaking gas and some needed warrantly work (oil leaks on new engine), I had them put on the rebuilt Qjet when it came back from the expert rebuilder. It wouldn't run and when I went to pick up the car, I found that they had put on an old AFB they had in stock and I was so grateful to get my car away from them and it ran great, that I drove away with a carb I didn't want...
so, now my quest, believing that my qjet cannot be rebuilt correctly, and not having a mechanic I trust, is to just buy a new carb that meets my needs. It just appeared from my reading that the Edelbrock would be the fit the best, need the least amount of tinkering and give me basically a good sound all around carb without a lot of rework.

 

I'm not going to get into this one. I've see threads go on for days regarding peoples loyalty to one carb or another. All I can say is I didnt do anything but bolt on the 1406 & mount the bracket I mentioned to two intake bolts and I was idling and drove away!! Period. They are as simple as they come. Maybe not the best choice for a 400 + hp performance monster, or 1/4 times, but it doesnt sound like that's what your looking for.

 

Cherrybomb, Thank you !!
That's what i'm looking for!

 

It sounds to me like your getting upset
Go with Edelbrock 1406..I just hope it runs properly out of the box because you have stated your engine is not stock and you needed a mechanic to install it..

As far as Edelbrock 1400 series VS the Qjet, Ill leave that up to your own research ...Basicaly one is a square bore and the other is a spread bore variable CFM
One has been tried and true for 25 years and one is fairly new to the market.
I will not get into an arguement over carbs..Ill leave it to you to make the choice
I also suggsest you find a new mechanic.

Unless a QJet has physical damage it can be revived/rebuilt providing you have the right person doing the job

It is also possible that perhaps the carb is not your main problem
Maybe ignition is the main issue..who knows as you never explained the symptoms in detail
Good luck
Bob

 

Yes, it is supposed to be a direct replacement for the Q-J. Some on the forum have the spreadbore Holleys.

The Edelbrock square bore is the AFB. Now that you have the AFB installed, the Edelbrock square bore is a direct replacement. You might want to run it awhile & decide.

PS Edelbrock also has new Q-Js.

 

I just rebuilt my Q-Jet today. It was running exceesively rich, loading up and spewing out the top when I shut off the engine. I went over to Autozone and bought a $35.00 Rebuild kit and a new float for $10.00. I took me about 2 hours to do the job and when I put it back on it fired right up and ran nice and smooth. I have never overhauled a Q-Jet before so I was a little apprehensive about tackling one on my own. It turned out so be easier than I expected, it was pretty straight forward as long as you pay attention to what goes where as you are taking it apart. I am still going to sent it to Lars once he is off hiatits to have it done right, but if I can put one together and make it run than you definiately need to find a new mechanic. The Q-Jet is an awesome caburetor and as stated earlier, unless it has physical damage to it they all can be made to run like new.
