I'm looking on what to expect when goin to edelbrock from a quadrajet
I happen to have a edelbrock 1400 I wanted to knw if it will perform better than a stock Rochester quadrajet and I knw the common one is a 1406 but this one I have is a 1400 what's the difference? And is it worth the swap?
-
How about a little more detail on what you currently have? Engine, trans etc?
-
It's a 2wd 1/2 ton with a stock 305 and a 700r4 trans

It'll work but you will need the correct base gasket or adapter depending on your intake manifold. The 1400 should have the bowl vent like the Carters had. You will probably need a different return spring bracket and or modify your throttle cable bracket. You will need the correct post stud for the TV cable. I recommend an inline fuel filter as well you may need a different length air cleaner stud or spacer depending on your air cleaner base and height.

8018 Edelbrock for the TV cable

Reliably, the 1st edelbrock carburetor I bought, It was my senior year in high school
12yrs later I bought another just because the other 1 had age so bad meaning looks wise and the new 1 runs even better. Very pleased

Ok so finally got around to swap out the quadrajet
Just had a clearance issues so had to remove the egr valve
I'm thinking I can just block it off for now am I right?
Also was wondering if my tv cable goin to be fine at the angle that it's in?

I have a adapter for a quad to square bore carb.
-
You can block off the EGR or just use a carb spacer. An adjustable throttle cable/tv cable bracket will allow you to dial it in just right.
-
Would that work where I have it
I believe is the hole for the return spring that's why is at an angle a bit
Also I do have a spacer since I'm running stock manifold still wouldn't clear the egr valve I'll just be blocking it off tho

Did some more googling and YouTube and I came across this bracket to correct the geometry on the tv cable
(http://uploads.tapatalk-cdn.com/20161025/f536df01b338aa1fb3415b33935a619e.png)
Is this the best way to go??
And also would I still need the adjustable bracket that mounts to manifold?
Thanks for the help just worried about my transmission Dnt want to mess it up!

I know this is an old post, but did you ever get this solved? I am currently going through the same thing and information is very hard to come across.
-
The post stud can be flipped around to the inside.

I spent big money to get the edelbrock tv cable situation perfect. Bow tie overdrives is the easiest and best way. My 700r4 shifts perfectly now.

I have a few Quadrajets and was just reading up on them and the conclusion seems to be that they are better than either Edelbrock or Holley as they are more streetable and get better fuel economy, etc. Seemed like reading forums what guys said was the only advantage the aftermarket carbs have is that they are easier to tune - which is more important for use at the strip were your constantly tuning, for the street I dont think there is any advantage there. Guys use Quadrajets on race cars still, they are good for big horsepower etc.; the Quadrajet on my C10 is 750 CFM - they were only offered in 750 CFM or 800 CFM models on GM cars around these years - your Edelbrock 1400 is only 600 CFM.
