Quadrajunk to Holley Conversion help!

The ironic thing is that the Qjet and Edelbrock/Carter have a lot of functional similarities. Yet fans of either are typically polarized. Personally, I run (or have run) all three and each has it's place. I like the Edelbrock on mild street crate motors and have had good luck with marine applications too. I like the tuneability of Holleys for performance applications. For factory stock applications, I love Quadrajets. The jetting, linkage, choke, plumbing, and fit are all as the engineers intended. They just plain work the best. Aside from getting dirt in them over the years and the occasional gasket leak about the only problem they develop is worn throttle shafts -- which is a pretty easy fix. That being said, I'll almost always try to fix a Qjet before replacing it with something else.
The only real reason there is blind hate on a quadrajet is because people that get them are usually on a car that has been sitting. Fuel turns to varnish the gaskets dry up the carb gets gummed up then people say oh well its cuz its a Qjet. Take all 3 let them sit and rott they will all do the same thing its just natural.
But ive had all 3 Qjet Holley Edelbrock NEW. Malibus got an edelbrock right now only because my buddy at autozone gave me half price on a new one. The new double pumper holley i bought its in a milk crate because the floats kept sticking flooding it out yes this was a new holley out of the box that ive never tore into this is just what it did after about a month being on the car. As for my new Qjet i bought its still goin strong on the scottsdale white flat bed thats got almost 400,000 miles put it on 280,000 if that tells you how good these carbs are.
Get a good Qjet you wont regret it.

I agree, absolutely agree.... but...when a Qjet goes wrong, or someone inexperienced gets into them, they never function right again.DoubleV said:
I was saying for sheer simplicity, for a dd and not a performance application, the ede 600 is an easy choice.
I had my Qjet rebuilt and it works fine. Still had to fine tune the idle air bleed with the engine running but any carb will need fine tuning on a running engine. However there are a few thing to watch out for with Qjets. Such as reman vs rebuilt, reman refers to the carb being cleaned and built to generic specs, sometimes cobbled together from mismatching Qjets, while rebuilt means restoring to original factory specs. Then there are low grade rebuld kits with cheap soft parts that can't take E10 and generic spec hard parts vs good rebuild kits with E10 proof soft parts and factory spec hard parts. Also unlike most aftermarket carbs, Qjets were built to be appreciation specific. That is a Olds Qjet is set up very differently from a Chevy Qjet which are both different from a Buick Qjet and etc. Reman Qjets they try to convert them to be universally fit and fail. Qjets are built for their intended engine, they are not universally fit like Holley or Eddy carbs.
This isnt true at all unless you have no idea what your doing. When I first got my car I thought I could tune my carb(ironically it was a Qjet). Long story short I screwed it up so bad it wouldnt start again. I mean I really ****ered it up bad! My dad called a buddy of his and within an hour or so it was running better than before I tried to fix it. It ran perfect for over 3 years of daily driving until I parked it for body work. After body work was done(9 months of sitting later) it fired right up and runs perfect to this day. The only reason this Qjet is getting redone is because im running it on my 496 and need to get it set up for the bigger engine, not because it ever failed me.bygddy said:
X2 ...or someone puts one back together/on without using a torque wrench (to specs) and tweaks the crap out of the body, warping it to hell...
