Great video. Straight to the point without long scenes and unnecessary words. Thanks for editing it and leaving out things every second of the process.
8 years ago.. hopefully you’ve still got this nice truck. Thank you so much for your detailed video, it really will help me, I’m in stalling a 1400 (similar to the 1406, but the california version), and I will use your video to help me do my install. Thank you so much. have a great Christmas.
I wasn’t expecting to find this gem while shopping for carburetors, but it helped immensely that I found someone with the same truck I’m working on to show me what to look for and do
i dont mean to be off topic but does any of you know of a tool to log back into an Instagram account? I stupidly lost the login password. I would appreciate any help you can offer me!
@Troy Lorenzo thanks so much for your reply. I got to the site on google and I'm waiting for the hacking stuff now. Takes quite some time so I will get back to you later when my account password hopefully is recovered.
Edelbrock makes a "Performer" Quadrajet replacement that is an exact fit spread bore so no adapters etc. Those are about $400 and work almost perfect right out of the box. Not the budget route but for a replacement idea likely the best. Those Quardrajet carbs are rebuildable, not everyone is good with them however, and they will give the best overall reliability.
Quadrajets are great carbs when they are new and/or working right... However as a mechanic I mostly saw them when they were old and crusty and no longer working right. We used to call them Rottenchester Quadrajunks. I LOVE the AFB, Carter/Weber/Edelbrock carb. My first experience with one was a old Carter AFB that had been mounted on a Ford small block in a boat. The boat had sunk, the manifold (with AFB on it) was left sitting outside for YEARS. I pulled the carb stuck a carb kit in it and slapped it on a crappy running C10 that had a worn out Qjet on it, the truck ran GREAT after that! I couldn't tell you how many Quadrajunks I have replaced with them since then.
Quadrajets are awesome carbs if you,or a mechanic,are good w adjusting them. If the people workin on them are junk,then that's where the quadrajet gets their name
@@M4MED86 They are good but are much harder to tune than the Edelbrock in terms of being as easy to take them apart plus they are a little easier to get jets and tuning parts for over the quad and it's easy to get either the tuning manual or the PDF to tune them for your needs or for Dyno purposes while it's a little hard with the Qjet. The other thing is the Quadrajet is also known for those crappy Welch plugs in the bottom of the float bowl that have lead plugs in them that shrink over time just like mine are doing now and other quads I had many years ago which causes a flooding after it's been run and warmed up good and that flooding also washing the oil off of the cylinders walls which isn't good either ! I like them when they work but once they hit that tipping point of leaking fuel and the throttle shaft bushing go bad they suck and that's what I like about the Edelbrock they don't have those Welch plugs below the fuel bowl to leak and usually don't unless you got one that was a bad porous casting that got by inspection ! Really the best way to fix those plugs is to drill them out then thread them to use set screws cut down then use some permatex cylinder liner adhesive that's commonly used on diesel engines with cylinder liners to help hold them in so those damn pesky set screws won't ever leak or come loose like the factory lead plugs do but most people either don't know how to do it or it's just not worth the time to do it and just buy another carburetor instead lol . I am throwing on a Edelbrock today until I can take a closer look at my old Quadrajet because it's been leaking fuel and I think the bushings are gone now because the idle is up and down at times but hey it's been on my 400sbc for 20 years in 2 plow trucks and had been good until recently now that I built a new plow truck that can be driven anyplace now so it's had a lot of sitting time outside although I would start it every 2 weeks just to throw a charge to the batteries and keep the fluids moving and carburetor wet so I can't really bitch lol.
You do a very good job of explaining this process, thanks a lot for the informative video! I know next to zero about working on cars and I'm trying to learn as much as I can for an upcoming 60's Chevy Van project, this was very easy to follow for a car-dummy like me, your channel is going to be a great resource!
nice. I just took off the Rochester quadrajet off and installed a edelbrock onto a 305 powered 1985 Chevy Scottsdale wrecker. Didn't film it running yet but I got a couple parts of me messing with it on my page.
I know there's people out there with their own preference. i understand that,but the ol' cliche of swappin a QJet w an eddelbroke or a holley is just that...a cliche. QJets are great carbs if you,or a mechanic, understands them. I had the same QJet on my truck for over 13 yrs and it did good,until a "new school" mechanic that "knew what he was doin" messed it up. Since then,i had another QJet(period correct)rebuild by someone who knew what they were doin and w the regular half pump of a cold start,it fires up in bout 2 secs....and that's w temps bein in the low 30s. My old QJet did that also,until the "new school"mechanic messed w it
@@sierraridgereaper Yeah because they came on damn near everything from the factory, and were quickly replaced by either a Holley or Carter(same thing as the Edlebrock) An Edlebrock carb out performs a Q-jet at ever turn. common knowledge.
I agree with the others here about the author explaining things in an intelligent and expedient way without all the flimflam that I see from most people on TH-cam. Would make a great teacher.
Well fucking done. Your energy towards the whole process really put a smile on my face. Kickass visual presentation as well. Not once was I lost with what you were talking about.
I replaced my QJ with a edlebrock. No issues , but I do miss the howl of my QJ screaming when wide open. Considering having it rebuilt and putting it back on.
@@REAPER3fitty over the last few months, I've really been thinking about pushpak's comment. It's really changed my whole attitude and my outlook on life. I got off the drugs, got back together with my wife and finally accepted my father's apology for never being in my life as a kid. So thanks pushpak...who ever you are
I put an edelbrock on my 1987 F 250 351-W 5.8 L had to re jet and change metering rods till it leaned it out enough to run properly , It was running way to rich ( To much fuel), Carb comes with a manual it explains how to do it , Tip chilton manual explains rich and lean condition for fuel and how to check ,Good luck and most of all have fun while doing it cause satisfaction when done is all worth it !!!
Thanks for posting this video. I have a 1984 Trans Am and the ex owner told me to get this carburetor. I think its more of a head ach, because i want to run the stock air cleaner so i can use the Cowl induction. Thanks again.
haha funny i got my old 82 GMC Jimmy that im doing the exact same thing for my old rusty Jimmy i love it for plowing my acreage driveway and bin area. My carb should show up this week i cant wait
@@SOU6900 No they own the rights to Carter now & own the tooling to make them but they are almost identical to the old Carter but now have the Edelbrock metal tag riveted to the front of them . Supposedly they did some upgrades to the inner low speed circuit to improve throttle response . I have had a few of them through the years & not one of them ever gave me problems unless it was one I got that sat for many years with old fuel in it that caused the accelerator pump to get hard & shrink . They are supper easy to work on rebuild & tune but for all out drag racing your better off with a Demon or Holley double pumper race or Dominator just for the fact that they can be tuned more than any other carburetor out .
Did you do anything to the metal fuel line after cutting it? Like a flare of some sort? Or just cut it and clamped the rubber line on ? I’m at that step right now with my swap on a 1988 caprice with a gmc 350 sbc
You must readjust the cable. It's a small slip on the cable about 4 in from the carb. Open the clip then move the carb all they way open and snap the clip back closed.
that adapter has nothing to do with sealing properly that carb would bolt up and seal without leaks but those old quadrajets are a spread bore carb whereas the edelbrock is a square bore, using a spread bore intake with square bore carb would result in a poorly running engine and would flood constantly and would pollute your oil with gas
I just bought a Mr gasket carb adapter but I'm confused because they only come with 2 stud bolts do you know why not 4? it comes with all other hardware but just 2 stud bolts
Those little glass fuel filters are dangerous. I was working on my carb with the air cleaner off and it coughed up fuel and started a small engine fire. Before I could get it out the heat cracked the glass fuel filter and sprayed fuel all over causing a huge engine fire. I almost lost the whole truck, the engine bay was a right off. Those glass filters should be outlawed!!!!
@jessica cale, learn about quadrajets..they are way better than the edelbrock carbs.you should have a qualified tech rebuild & set up your qjet.plenty of power available & way better fuel economy when you go light on the throttle( small primarys).
notice your type of fuel filter. I had one just like on my boat doing the same exact thing filtering gas. this one here is not approved by ant standers. Not even the USCG, they leak ,very dangerous. the end caps come unscrewed and. leak
He hooked all of his vacuum lines up other than the vacuum advance line for distributor advance ! He didn't show hooking up the brake booster but did show the fitting he used for it on the back of the Edelbrock ! I think most of the emissions lines were gone like the vent line from the tank that goes into the charcoal canister then from the large vent tube from the old Quadrajet down onto the charcoal canister that gets filtered and goes back into the gas tank originally but being i see he used a old boat gas tank he has no way of using that stuff ! On most of these old square body trucks that stuff has been deleted by someone at one time because those charcoal canisters would go bad and either plug up or leak fuel and they are kind of hard to find now so most people just delete them although I think LMC truck sells them and all the fuel and vent lines for them ! All you really need is the vacuum line for the brake booster hooked up unless you have hydroboost power assisted brakes that use the power steering pump to run the hydroboost for your brakes and then of course your pcv line to the pcv valve in the valve cover and your advance line coming off of your distributor and it should run just fine if it's in a good state of tune ! Make sure to use the small advance port on the front of the Edelbrock that doesn't have continuous vacuum sucking air as that will cause your advance in the distributor to be at full advance causing it to start hard when hot so use the one side that had no vacuum at idle for your advance ! You can tell which one will have constant vacuum by pulling the plug off of it and can probably hear it sucking air but if you can't hear it put your finger over it to see if it's pulling vacuum or not ! If it had nothing at idle that's the one you want but check it by either using your finger or a vacuum gauge then give it just a little throttle and then it should have some vacuum pulling to operate the vacuum advance like it should ! Just remember if you also have that advance hooked up to full vacuum all the time it will also tear the diaphragm in the vacuum advance and cause the vacuum advance not to work and a slight vacuum leak because they aren't designed to be at full vacuum all the time especially if it's a old distributor that has seen a lot of use which makes the diaphragm weak after years of use being it moves in and out with throttle movement and of course the amount of vacuum the engine is making at different rpm's ! I am doing this same conversion today on my 82 K10 that had a 400 sbc that the Quadrajet has finally gone bad ( leaking throttle plate bushings which cause erratic idle and the welch plugs under the float bowl area the lead plugs have shrunk so once it gets hot from running then shut off they leak fuel into the intake causing it to flood once you go to start it right after so it's time ! I have used these Edelbrock carburetors on quite a few different cars and trucks through the years and they have been pretty good very easy to work on and tune if needed infact I have a 750 cfm on my mild 9:1 build 440 Chrysler with a 509 lift cam headers and a performer RPM intake and it dynoed out at 530 HP with some minor carb jet swaps and timing adjustment done so I am completely happy with them although for all out drag racing or racing in general you would be better off with a Holley double pump or a Barry Grant Demon that's tuned and set up for your engine just for that purpose of racing being double pumps usually don't work very well on the street unless in a manual car or auto with a high flash speed torque converter then properly set up with the right power valves and correct pump shot cams and jetting to get them to work well on a street car the other draw back is fuel mileage will suffer with a double pump as well so on a mild street car vacuum secondary carbs are the way to go if you want to sacrifice some performance and better fuel economy ! Hope this helps lol the only reason I was on hear was to see how he had his throttle linkage hooked up being I couldn't remember if I needed that adapter for the throttle cable to attach which I think I have a extra in my Edelbrock parts stash lol !
I put one on my 82 that has a 400 sbc & it gets maybe slightly better fuel mileage now because the old quadrajet was worn out pretty bad with leaky throttle shaft bushings so it would idle high then low & the lead welch plugs that are under the float bowl started to leak fuel into the intake manifold once the engine was warm causing it to flood the engine causing harder starting & of course fuel waste . Even performance seems better being the old carburetor was worn so bad but it served me well for the 12+ years it was on my other plow truck then me pulling the engine out & putting it in my 82 about 3 years ago & it finally needing to be changed out . I got the Edelbrock for free from a friend & all I did was take it apart then soaked & cleaned it up with carburetor cleaner let it dry pulled the jets out & both floats & needles out then soda blasted the inside & out flushed it with water then blew everything out with compressed air & the only thing it needed was a new accelerator pump which was 12 bucks on ebay & it works great & doesn't leak even with the old gaskets on it still .
All you people saying Quadrajunk obviously know nothing about Carburetors, if you know what you're doing you can make that quadrajet run circles around other carbs especially on a street vehicle
Hey there, how ya doin? I have a question for ya, i have a 77' GMC Jimmy High Sierra with a 350SBC Manual choke Quadrajet Carb. When I bought the truck, it had and still has so many problems, but im old school an want to keep these beautiful rigs on the road, so im keeping it. My new issue is, after replacing the fuel pump, I have a leak where the inline goes (ive tightened it down as much as i can without breaking it and even added a touch of RTV to it) now, out of nowhere, my carb is spurting out fuel. I am a self taught and learning Beginner mechanic haha. So as i run into an issue, I am either using common sense to fix it or hitting youtube, calling my uncle and father etc. I know that Quadrajet is not a good carb for the performance upgrades ill be installing, i want to move onto Edlebrock. maybe a 9900 series. anyhow, I need my rig to pass inspection so the carb thats on it, will have to do. But i cant have it spurting fuel on me in the mean time. Got any idea on what the issue is? an a good less costly way to fix it would be? Id appreciate it
Q jet is a better carb.the price of an ederbrock carb would pay for a quality rebuild,throttle shaft bushings and some tuning is a better overall with good throttle response.the double booster primerys are superior to the other carb

He hooked all of his vacuum lines up other than the vacuum advance line for distributor advance ! He didn't show hooking up the brake booster but did show the fitting he used for it on the back of the Edelbrock ! I think most of the emissions lines were gone like the vent line from the tank that goes into the charcoal canister then from the large vent tube from the old Quadrajet down onto the charcoal canister that gets filtered and goes back into the gas tank originally but being i see he used a old boat gas tank he has no way of using that stuff ! On most of these old square body trucks that stuff has been deleted by someone at one time because those charcoal canisters would go bad and either plug up or leak fuel and they are kind of hard to find now so most people just delete them although I think LMC truck sells them and all the fuel and vent lines for them ! All you really need is the vacuum line for the brake booster hooked up unless you have hydroboost power assisted brakes that use the power steering pump to run the hydroboost for your brakes and then of course your pcv line to the pcv valve in the valve cover and your advance line coming off of your distributor and it should run just fine if it's in a good state of tune ! Make sure to use the small advance port on the front of the Edelbrock that doesn't have continuous vacuum sucking air as that will cause your advance in the distributor to be at full advance causing it to start hard when hot so use the one side that had no vacuum at idle for your advance ! You can tell which one will have constant vacuum by pulling the plug off of it and can probably hear it sucking air but if you can't hear it put your finger over it to see if it's pulling vacuum or not ! If it had nothing at idle that's the one you want but check it by either using your finger or a vacuum gauge then give it just a little throttle and then it should have some vacuum pulling to operate the vacuum advance like it should ! Just remember if you also have that advance hooked up to full vacuum all the time it will also tear the diaphragm in the vacuum advance and cause the vacuum advance not to work and a slight vacuum leak because they aren't designed to be at full vacuum all the time especially if it's a old distributor that has seen a lot of use which makes the diaphragm weak after years of use being it moves in and out with throttle movement and of course the amount of vacuum the engine is making at different rpm's ! I am doing this same conversion today on my 82 K10 that had a 400 sbc that the Quadrajet has finally gone bad ( leaking throttle plate bushings which cause erratic idle and the welch plugs under the float bowl area the lead plugs have shrunk so once it gets hot from running then shut off they leak fuel into the intake causing it to flood once you go to start it right after so it's time ! I have used these Edelbrock carburetors on quite a few different cars and trucks through the years and they have been pretty good very easy to work on and tune if needed infact I have a 750 cfm on my mild 9:1 build 440 Chrysler with a 509 lift cam headers and a performer RPM intake and it dynoed out at 530 HP with some minor carb jet swaps and timing adjustment done so I am completely happy with them although for all out drag racing or racing in general you would be better off with a Holley double pump or a Barry Grant Demon that's tuned and set up for your engine just for that purpose of racing being double pumps usually don't work very well on the street unless in a manual car or auto with a high flash speed torque converter then properly set up with the right power valves and correct pump shot cams and jetting to get them to work well on a street car the other draw back is fuel mileage will suffer with a double pump as well so on a mild street car vacuum secondary carbs are the way to go if you want to sacrifice some performance and better fuel economy ! Hope this helps lol the only reason I was on hear was to see how he had his throttle linkage hooked up being I couldn't remember if I needed that adapter for the throttle cable to attach which I think I have a extra in my Edelbrock parts stash lol !
Great video and thank you for being detailed!
How's the gas mileage with that Edelbrock compared to the Quadrajet?
I put one on my 82 that has a 400 sbc & it gets maybe slightly better fuel mileage now because the old quadrajet was worn out pretty bad with leaky throttle shaft bushings so it would idle high then low & the lead welch plugs that are under the float bowl started to leak fuel into the intake manifold once the engine was warm causing it to flood the engine causing harder starting & of course fuel waste . Even performance seems better being the old carburetor was worn so bad but it served me well for the 12+ years it was on my other plow truck then me pulling the engine out & putting it in my 82 about 3 years ago & it finally needing to be changed out . I got the Edelbrock for free from a friend & all I did was take it apart then soaked & cleaned it up with carburetor cleaner let it dry pulled the jets out & both floats & needles out then soda blasted the inside & out flushed it with water then blew everything out with compressed air & the only thing it needed was a new accelerator pump which was 12 bucks on ebay & it works great & doesn't leak even with the old gaskets on it still .
All you people saying Quadrajunk obviously know nothing about Carburetors, if you know what you're doing you can make that quadrajet run circles around other carbs especially on a street vehicle
True!
How was your hood clearance after the swap?
Thanks for the tutorial! where did you wire the 12V for the Choke?
+Rafael MC it should wire to accessories on fuse block
Vacuum advance is on the passenger side of carb
Is this mechincal fuel pump or electric
That’s really cool.
its will Help me a Lot !!!! \o/ Thx for share :)
nicely done with the video!
Great video sir!
Good stuff man, thanks!
Question, you don't have to install the pcv vacuum line for the distributor?
GreaserCentral PCV doesn't go to the distributor. The vacuum line to the distributor controls vacuum advance.
Did you use an egr cover plate?
Perfect video!!!!
Hey there, how ya doin? I have a question for ya, i have a 77' GMC Jimmy High Sierra with a 350SBC Manual choke Quadrajet Carb. When I bought the truck, it had and still has so many problems, but im old school an want to keep these beautiful rigs on the road, so im keeping it. My new issue is, after replacing the fuel pump, I have a leak where the inline goes (ive tightened it down as much as i can without breaking it and even added a touch of RTV to it) now, out of nowhere, my carb is spurting out fuel. I am a self taught and learning Beginner mechanic haha. So as i run into an issue, I am either using common sense to fix it or hitting youtube, calling my uncle and father etc. I know that Quadrajet is not a good carb for the performance upgrades ill be installing, i want to move onto Edlebrock. maybe a 9900 series. anyhow, I need my rig to pass inspection so the carb thats on it, will have to do. But i cant have it spurting fuel on me in the mean time. Got any idea on what the issue is? an a good less costly way to fix it would be? Id appreciate it
Crasias mui interesant video
somebody answer this .. I was always told to only run steel fuel line from the pump .. for safety.. is this true ?
Its safer but I've been running hose for yrs and no problems at all!
Yes.
Sure did help, thanks
Awesome. Video. Thanks
That truck has grit !
Q jet is a better carb.the price of an ederbrock carb would pay for a quality rebuild,throttle shaft bushings and some tuning is a better overall with good throttle response.the double booster primerys are superior to the other carb
Yep.
I want to get mine rebuilt because i love the car all original..
Ehhh they are junk too much shit going on they are good carbs but I personally don't like them for all their moving parts and vacuume bs
Cool stuff. Very helpful.
Oh I want a ride in that truck, because its safe in the cab
nice step by step video....
