Will this float bowl fit on my Quadra jet for my 307 V8?

[JayShizzle]

Hello, just wondering if this code is gonna work. Guy I bought it from said it will fit he seemed to know what he's talking about, just wanted to double check before I decided to take it apart and rebuild it, unfortunately the guy that had this before JB welded the filter housing, great idea right Hahaha. Gonna be a big job for me, first time rebuilding a carb, any tips I should know about would be appreciated thanks!

Code on my new bowl is 17083287, my current bowl is 17084287. Tried to send pictures in here but don't know how.

Anyways, the number on top is only one digit from mine. It's for the 1983 olds, mine is an 84. I'm gonna be taking my Jets and all my gear from my current carb, only has 80,000k so it has some life in it, and transfer it to the new setup.

Thanks,
Jay

I tried, how do you guys make the link for the pictures? I tried copying it as a google drive link, didn't work. Do you guys usually use drop box or something? I'm new to the site

You are describing the main body of the carburetor, not a float bowl. Do not transfer parts. The new carburetor has matching air passages to the jets and rods it came with, switching those parts around will result in a possible issue. Which carburetor has the JB welded fitting your old one or the new one? If the new one, why aren't you rebuilding your current carburetor?

Thought it was called the float bowl? What's the float bowl then? I thought the bottom half was the float bowl, I'm gonna have to get new Jets and rods so it's compatible. My old one (current) has the JB weld, the filter is all jammed up now and It doesn't want to start so I have to tackle this next instead of the vacuum lines, can I just replace the jets and rods to make it work with the new bottom half?

Unlike Holley carburetors, Quadrajets have the float bowl as part of the main body. Just use the new carburetor, rebuild it if necessary, but do not use the old parts from you carburetor, jets, rods, power piston etc. Jets and rods do not wear out assuming they are not corroded from water.

Alright thanks. I'm gonna get new jets and rods for sure, contacting a rebuilder hopefully I get good news on Monday.

Did you open the carburetor and look at what jets and rods it uses and their condition?

They look to be pretty good, the carb is pretty new. Too be honest with you I don't know where the rods are located though. If you could tell me what they look like that would be awesome. Is it just under the two damper valves?

How can I tell which rod and jet to get? Will it say on the new carbs code? I just wanna make sure I'm getting the right one. Or do they not have an ID

Jets and metering rods are not wear items so they should not be changed unless they're damaged or corroded due to rust. MelsRegal already mentioned this. A good rebuilder will know what needs to be changed.
On second thought you may be better off just buying a new Edelbrock carburetor. I hear that they are generally "plug and play" right out of the box.

Please don't take this the wrong way but the Quadrajet is much more complicated than a Holley and the fact that you don't seem to be familiar with it's components is troubling. It has both primary and secondary rods. Again, they normally do NOT require replacement. Buy this book and read it before doing anything.

Why is that troubling? I'm in my early 20s this is all new territory for me man, that's why I'm coming to the forums. I didn't study the internal components of the engine before I bought it, I'm learning just like you probably had to do as well. Stuff like this is the reason carburetors are gonna phase out one day, it's not very encouraging when guys respond like this. Just trying my best here.

Is this the only issue with your original carburetor? If it is, you should consider removing it ,and verifying what they were JB welding. My guess if they were dumb enough to do this, its simply because it leaked. Once thats verified, you should consider a professional rebuild, the qjet isnt a good carburetor for first rebuild.

I first rebuilt a very simple carburetor on a lawn mower from the 80s for my first one, it was like this:

The qjet is good carb especially for your 307 which is gonna fall flat in performance with a square bore carburetor, and holly would be okay but you would be overcomplicating and wouldnt get the same mileage either.

 

[BuickGirlFromMars]

Heres my 77 Electra's qjet. see how it has physical differences? These differences lead to things being particular to each model difference and needing to stick to what you got ideally

I responded by telling you to educate yourself with the book I gave you a link to before diving in. How do you think people learned before relying on the Internet.

I mean, carburetors are already phased out on cars and small engines are pretty much about there too, its not that they dont work its just emissions/electronics give more control. they are still cool and have a place.
Im in my late 20s (26) and i havent tried rebuilding a qjet, im going to have mine sent off when its time, personally. Theres a lot to itm, the most complex carb that let gm meet emissions with a lot of engines for many years easily, other types just didnt have the same adaptability. Also, if yours were electronic carburetor (sensors on it) it would be more complex given there would be computers involved but yours dont seem to have that

I rebuilt many back in the day but as said it's not for the novice. I doubt any hard parts are worn and a simple rebuild kit will be good for either carb. Check and make sure the other carb has the same vacuum ports linkage and choke configuration as the original carb. The book posted above is a great reference. They do sell helicoil repair kits to fix the fuel inlet fittings. Also buy a good rebuild kit and not the cheap knock offs. AC Delco Gold is a good kit for around $30.
