The Quadrajet is the closest you will come to fuel injection results without actually going to fuel injection. You can control and tune every aspect and range you need with these carburetors.
One thing I am surprised they never addressed was the throttle shaft wear. The base plates should have had bronze bushings installed from the factory.
So the Monte Carlo was ahead of its time I never knew power mirrors existed back then and I never heard of auto leveling rear end
Had many cars with them as a teen. We called them "Quadrabogs". Replaced with spread bore Holly's
The real issue I had with the Qjet was no matter what I did the secondaries just wouldn't kick in on my truck.
The choke has a safety deal in the linkage. If the choke or that linkage thing has an issue it will prevent the back barrels from kicking in.
Quadra jet carbs are great carbs. Rather have a Q than a Holley. That’s just me tho. Who the hell wants to pop the bowl off just to mess with the power valve.
“This paint is made for outside the carb only” doesn’t tape up carb whatsoever and sprays directly into ports
It’s going on your car so they really don’t care.
And once the air cleaner is in place you won’t see or be aware to notice anything until the 30 days warranty expired.
And they’re still going to charge you for the “ Professional re-plating” of the body, an extra $375.00.

You've got that right.
Today on powernation we are gonna do a budget build truck! *3 episodes later* Alright our budget build was $45,895! Wow that was cheap!!

Q-jets are great carbs! I would grab every one off the big block caddy’s in the junk yard and build them for my small blocks. If you kept your foot out of it they would get great mileage but when you stomp on them they made the best throaty sound when the toilet bowl secondaries opened up. And I was familiar with all the tricks they talked about in the video.

Its been a long time since I had rebuilt a Q-Jet. When I use to run them back in the 80's and early 90's I had nothing but great results using them on my '70 Nova, '77 El Camino, '67 Catalina, and '82 Trans-Am.
Brown recluse spider ya got right there...
Nice rebuild..thanks

Been building Q-jets for a while & You guys did a fair job but missed a few critical items. First off the Q-jet is a fairly complex carb w/real good metering aspects, the small primary bores will give your engine good throttle response at low speeds. After using one a square bore will feel mushy at low speed by comparison. Spread bore unlike any other? What about the Carter thermo quad? To remove the screws holding the throttle butterflies in place better grind off the part of the screw that extends beyond the throttle shaft or you will likely break the head off the screw & will have hell removing what's left of the screw. The end of the screw is staked at the factory to prevent them from backing out. I use a Dremel grinder w/ a small carbide burr to do the job. Screws for the bottom plug, 7/16" NF tap will work better. I have a length of 7/16" aluminum rod threaded to use for plugs. Base needs to be resurfaced on a large belt sander, they can be really warped. Same w/ the main body. The most common mistake owners make when they have a problem is to over torque the hold down bolts & warp everything. Easy way to check the main body for warpage is to look at the slots where the secondary divider plate goes. If they are wider at the top than the bottom then the main body is warped. I have a way of straightening this part but it is difficult & the process is too lengthy for discussion here. You neglected to cover the installation of the choke lever onto the choke shaft, a very frustrating process. On the chevy carbs the plug at the back of the fuel inlet is also prone to leak. Most times this can be corrected by driving the plug in tighter (it is a tapered plug) & re-peening the area around the plug. Lot of critical adjustments to make also, especially the choke pull off which controls the rate of opening for the secondary air valves. If not done properly the carb will bog at WOT or the secondary air valves will open too slow causing disappointing performance. You guys did a fair job otherwise.
And the thick gasket they used under them made it even easier to warp them
Back in the 70's when I was in my 20's I bet I rebuilt 30+ Q-jets when I was a mechanic working on boats with GM motors and friends muscle cars. Watching your video I was surprised how much I forgot over the years. Good video, thanks for the memories.
I love that: " Back in the 70's, when I was in my 20's" has a cool ring to it.

In the 70s I had hundreds of the Qjets apart. When built right they worked fantastic. I had a custom one off that I built for my LT1 never had anything else on the engine!
Actually they went to 850 cfm and i love Quadrajets. Used to make a bushing for the center also...worked wonders for tuning. You didn't need to put threaded plugs in it though. File down and then epoxy over the stock plugs and it good to go. Vinyl interior wasn't exactly "luxury" LOL and neither was the abhorrently bad fuel mileage
Contrary to popular misinformation stated here is that the Rochester Quadrajet grew to 850 cfm. There aren't any production Rochester Quadrajets for the '65 to '74 model years, only 750 cfm and 800 cfm models. The 1975 thru the early 80s were completely different from the early models.
If one uses a 72 jet & a 49 primary metering rod with a lite power piston spring over 20 miles a gallon can be had in the 396 & 402s. The 350 would get 24mph sometimes better with that set up. One would also have to tune the dist advance curve.
Setting the secondaries for power one could enjoy both worlds mpgs & tons of power.
The secondaries would take some drilling on some of the orifices & grinding on the metering rods.
The Q jets were fun to work on to get max MPGs & Max Power.
There was no other carbs that I built that could do the same.
That combination would render a total of 0.00218576’ which is way lean for a big CI engine like that. I’de look to experiment and look at the plugs-monitoring the temps also as that seems too lean which might create excess heat issue on top of the lean fuel ratio it would introduce.
The engineered spec chart call for at least a 0.0025000’ total fuel ratio mix for proper emulsification for proper 14.7:1 ratio for an efficient combustion.
@@ashqelon7267 One has to take in to account the power piston spring. With different spring tension one can change the fuel ratio. If one is not familiar Qjets the spring is under the piston where one hangs the metering rods.

Yes I known the pieces well
I am amazed at the knowledge required to rebuild a complicated carb ! Brain surgery has to be less complicated. So many small intricate pieces, and where to find exact sizes to place in exactly the correct way....my brain hurts. Seriously, are their real people that can rebuild a carb exactly correct ? On this planet ? 🤯
@@jerrysmith9315 They are one of my favorite carbs. I was building them back in the 70's - 90's. Now the are far & few between.
People are scared of them & buy the Edelbrock carbs, there ok just like the Qjet.
Epoxy is fine for sealing the soft plugs over kill to drill & tap them. 25 year ago i rebuild the computer controlled version of this caburator then set and adjusted them for AZ state emissions.
Quadrajets rule,best carburetor ever conceived,once properly tuned delivers glorious acceleration
I always hang my carbs upside down to check float level when they're in that position installed. It is a very important part as you said.
No doubt it's important to check, new parts can change things.
A lot of my friends play with small engines and always wanna get in there and adjust the float without knowing what it's supposed to be.
It's running like crap, that has to be the problem right?
In all my time I've never had to adjust a float on a small engine , unless a butcher has been there before.
Fun to see what ya find on an automotive carb when ya open em up too.
My buddy had a quadrajet carb rebuild by his girlfriend's father, haha he locked out the secondaries and my buddy never noticed 🤣
@@MrTheHillfolk part of the reason i have a love/hate relationship with plastic floats. Yeah they never go out of adjustment and barely ever leak, but goddamn do they get brittle after 40 years
Ya need to grind off the flares at the end of the flap screws before removing...

I run the car maintenance TH-cam channel in Korea. I'm always learning such a great ideas on your channel. I hope we have a chance to be together. Thank you.
No wonder why the mechanics charge you so high for one of this.
Also it is likely to come back on them. A lot of times the car owner will mistake an ignition problem for a carb problem.
@@larryhutchens7593 u think mines a carb problem? I have to put gas in my carb everyday
Whoa, I just took a quadrajet appart for a rebuild! Nice timing!
My uncle rebuilt and customized my Quadrajet to be better then Holly. Apparently. Some of the parts he took completely off and left them off. It worked perfectly.
I'm a retired mechanic I have rebuilt many Quadrajet carburetors carburetors and Transmissions are my specialty I can take the Ford carburetor and the Holley carburetors and it is easy to modify those carburetors to give you higher gas mileage I had a 65 Ford Galaxie 289 old motor 90 lb compression up to 120 lb compression pull a 5 by 8 trailer put about 100 pounds on the tongue of the vehicle and got 23 and a half miles to the gallon pulling a trailer going through Kansas and Missouri a big four door Galaxie 500 pulling a 5 by 8 trailer loaded never check the gas mileage with the vehicle only
years ago the Holley on my 73 mustang mysteriously got damaged during the engine rebuild. my friend offered me a quardrajet cheeper than replacing the Holley. I was young and broke so I went with it. he installed it and tuned it.... it was a massive upgrade on that little 351w compared to the factory Holley.
that was a very perverted part swap - did you just use an upside down holley adapter?
@@shiddy. no they make a square bore to spreadbore adapterplate
@@christophersallee7904 yep, that's an upside down Holley adapter plate
Ahh, good old quadrashit
10:00 for some fake screwdriver action...
A 327, Q-jet and powerglide.. amazing for the street. And my 68 Firebird would accomplish 26mpg, no emissions.
Thats what my 67 impala is 327 quadrajet powerglide!

I had my dad tune my quadrajet on my 77 RS/LT Camaro in 87. It would light the tires up from a dead stop.
My buddy had a girlfriend, and her father had a shop.
Dude was an awesome tech.
Anyways being a wiseguy , when he rebuilt my buddies quadrajet he pushed that little lever to lock out the secondaries...haha my buddy never figured it out.
That’s what every boomer says
@MrHillfolk what did he do exactly to that lever?
Woops you forgot all about the Carter Thermoquad.
Something I only recently found out is that when mercruiser marine first started using Chevy engines in the mid 80s they had their own version of a q- jet. It looks the same but it's already been modified for performance with bigger jets and passages. Marine application means no restrictions for emissions or power. They are also made up of a different kind of aluminum alloy that will not oxidize at all. My boat has a 307 out of a 73 Chevelle. I put the cam and lifters and the heads from a 300 horsepower 350 mercruiser that was sunken in salt water for a week. Then brought out of the water and sat on the shore for 5 years without being drained. The block was destroyed by freezing but the carburetor survived except for the little springs inside. That tiny little spring on the low speed metering rods was completely dissolved from the salt water and being left for 5 years. The inside of the carb just needed a can of brake clean with a straw and it looked like new. The exterior is already covered in black powder coat from the factory. All mercruiser carburetors have an aluminum tag with a part number to make it easier to get the right kit. Mine is from a 1985 four winns 25 foot cuddy. I had to scrap an old carb just for the tiny springs and I had to drill out the port and install a tube for the vacuum advance . Marine carburetors don't have any vacuum ports at all. If you need to hook up a brake booster you will also need to either drill and tap the port for the vacuum or even use a throttle plate from another carburetor that is the same. Just the fact that there is absolutely no corrosion anywhere inside or outside just blew my mind. It spent a week sunk at the dock and then 5 years on shore without being drained... Try that with an automotive carb !!!
Why didnt you just put a well plug kit in it ? Gas will desolve that epoxy n 60 days ! Go to my channel . Go back a year and thers a video on how to install well plugs ! Ben rebuilding them for 40 years now ! Ill take a q jet over anything !
ripped the TBI fuel injection off my truck for one of these. ABSOLUTELY LOVE THEM!!! i’m convinced these are the best damn carburetors out there!
hey you forgot to show replacing the injection spiders. it wont distribute the flow to all 8 cylinders without them...
good quick video though ive been contemplating on rebuilding the one i have but keep telling myself not to as its old and worn out. and converting to fuel injection is becomming affordable but this may be worth it to get my old vehicle back up and running again to enjoy next summer thanks guys.
ran my fastest pass with an 800CFM Q Jet on my 396BBC
I'll take a Q~jet for an off road application over any other make every time.
I was hoping they would have installed the quad jet and used it.
Yea i wanted to see it run!
No way, this is PowerNation
Instead of becoming a lawyer, I spent my youth fiddling with Quadrajet carberators and HEI ignitions making GM V8s run as though they were fuel injected -- idling perfectly, no surges or bogging, no detonation and good power and efficiency. I miss those days.
Sooo whats the secret to getting crisp response from the secondaries? New vacuum break? People dont like that secondary throttle stop lever i hear, but some experts say leave the secondaries stuff alone.. tho i have heard of drilling 2 tiny holes somewhere i forget, maybe in the secondary flap edges?
Really how about a performance tip, please and thank you..
I know i ran a 750 double pumper up against an unrebuilt qaudrajet same engine.. holley took it to task. Gotta at least tune the idle mixture screws for highest idle i know that much. Others have suggested the metering rods n jets.. but idk i never got that far.
stock Q-jet on a 350 is good for 700hp if you can tune them
Every butterfly bolt I have seen is peened on thread end. And needs to be slightly ground with mini wheel or the bolt will shear off.
Bobby Allison Coca-Cola Chevrolet.
427 Monte Carlo.
Cadillac used the same style as Chevrolet. Instead of removing the main well plugs just put epoxy on them. It will do the same thing. He also put the fuel filter in backwards.
lol 😆
Been there done that I can’t even count how many times.
Back in the day, my buddy was dating this girl whose father owned a shop.
He had a fast gto but couldn't drive so well.
So it's time to rebuild the carb, and he gave it to her dad.
He rebuilt it , did a nice job too.
Then he pushed the little lever down so the secondaries wouldn't open.
A fathers gotta do what a fathers gotta do.
My buddy never found out or even realized that he had less power 🤣🤣
The secondaries lockout cam. Accidentally flip it over when doing a rebuild and you're up shits creek when you jam on the gas.
Nobody gave the SS454 Monte ANY love in the comments. I'm sad now ...😢
I did
...and everyone thinking of rebuilding one of these just happens to have a blast cabinet.
I know this comment is 4 years old... but please. You don't HAVE to use a blast cabinet. Carb cleaner and some brushes or even a cheap Sand blaster loaded with baking soda will work
The Carter Thermo-Quad is also a "Spread-Bore" carburetor...
So... you don't want me to believe all the negative leaky reviews about the quadrajet, but then throughout the episode you keep telling me about all the common problems of it leaking. 6:29 LOL!
lack of maintenance on anything will cause poor results. preventative or routine. these carbs have stood the test of time unlike the many of the cheap off the shelf ones that people replace them with. and get thrown out long before the 30 year period some of these have been in service.
Yeah, because Holleys NEVER leak🙄
my 85 Dodge Diplomat came with a q"jet
It’s amazing to see how a rusty pile of garbage change into something... so beautiful
I plugged and drilled many air bleeds on them. Quick fix for warped base plate
Hey guys i had a quad in my garage for 3mths in a box. My throttles plates rusted shut. Pb blaster, soaked in rust restore, still locked. I dont wont to force it. Suggestions please?
*_There is something satisfying about watching them rebuild something completely reached out..._*

Hey Tommy Boshers looks a little younger in this series.
They used to call them a quadrajunk
Why would anybody criticize the quadrajet? It is without a doubt the best factory 4 barrel ever made. They rarely have any problems, and if they do, they're easy to fix and tune. I can rebuild them in my sleep... No need to drill and tap the plugs on the bottom. Just rough up the casting, and put your epoxy on. Most kits also have a sponge rubber seal to put in the baseplate to help with this problem.
Kenny,
I agree about the well plugs, I had one on my 76 caddy and even the small plugs were leaking. I found that by filling the fuel bowl with fuel and let it set over night the next morning I seen where it was leaking , and sealed them and the big well plugs with J.B. weld and worked great .
Those sponge seals rarely work for very long. Using epoxy alone will work for a while but the fuel will eventually attack it, especially the witches brew of fuel that is currently available & I'm not just talking about alcohol. The threaded plug idea is best since the fuel can attack the epoxy only at the end of the thread, takes quite a while to work its way through all the thread & cause a leak.

@@bertgrau9246 Use a blue paper shop towel & use paint thinner instead of fuel. Can spot the leak in just a couple of hours.
@@larryhutchens7593 I personally use a two part panel adhesive used for bonding body panels. It takes overnight to set up, but nothing will compromise that stuff. I've used it to glue windows back into the regulator tracks on old cars, and even glued a bumper bracket on a '56 Chevy that a customer had chromed without knowing the bracket was missing. I jacked the car up with his bumper jack the next day to show him it's strength.
Done several of these over the years.

Edelbrock performer carbs are best for the street. Easiest to tune and they stay performing great for years to come. A well experienced holley tuner may squeeze a few more hp from a holley but good luck getting it to stay that way. I've had a performer rpm matched top end set on our 64 Malibu. The original 283 is in storage. It has a 350 4 bolt main high hp version with powerglide twenty years ago I took the double pumper and torker 2 combo off it. The edelbrock stuff has been performing flawless all these years. Use stabilizer when you're not gonna drive your stuff. It saves alot of headaches.
Exactly!
hi, I have an unusual problem with a quadrajet I'm hoping you can help with
the return spring for the secondaries has broken - is there any way to fix or replace this part?
THANK for the great vid.
I need to know what is the purpose of the criss cross line( like a checker plate )on the throttle plates of most of the carburetor like the ROCHESTER QUAD ?
thank you very much
if Tommy is sellin it , im buyin it
I had an old ponitac that was in dry storage for 12 years - put up on jack stands. 400 engine with Q-jet and a 400 trans. Gas tank was emptied and the radiator/engine block drained. After 12 years i rolled it out into the sunlight, topped off fluids, and installed a battery. I primed the fuel bowl with gas, turbed the key and guess what happened.....nothing. I had to file the points. After filing and the points the engine fired and ran on choke like it was just parked yesterday. When it got warm i bumped the throttle and it came down to idle. I drove it to the gas station to top-off the tank. That was 5 years ago and it still runs great. Even the accelerator pump works fine. I haven't made a single adjustment on the carburetor. I never understood the hate surrounding Q-jets. They are a great carb if you know how to work on them.
For a guy like me that doesn’t know much about carbs but want to learn, this video moves way too fast. Not enough steps they show. More for experienced guys that are just watching for fun.

I don't know why you said the Grand Prix it couldn't be had with any performance the 1970 Grand Prix you can get the 455 HO with 370 horsepower and 500 foot pounds of torque and it was available in a 4-speed unlike the Monte Carlo the 454 is 360 horsepower 500 foot pounds of torque automatic only! I know my brother owned one in 1980 and it was a monster and it would put a whooping on a lot of those supposed muscle cars of the day !
It is funny how many people hate the quadra_junk carb. My buddy had one on his cj-5 on a fairly healthy 327 and it was the best carb he ever had. Worked better than fuel injection/ Never sputtered when wheeling and got 30 mpg on the road. All on a 400hp+ 327. It would actually pull wheelies on the street NO JOKE!!
Older the better.
good video on basic rebuild but there are a few easy mods that should be done to improve performance like sealing the secondary needles with electrical tape and re-locating the secondary linkage to get rid of the full throttle bog when the secondaries open. learned this from an article in Hot Rod magazine 35 yrs ago.
Q-Jets are great carbs. Had a '72 C-10 Chev Step Side short bed bought in '85. Gone nearly 30 years later in '12. Still ran and drove.
Anyways orig carb was acting up. Ordered a new one from a once staple speed shop thats gone now, sadly. This was '87 or so
Kept the orig and this was rebuilt by a family friend, '94 or so.
Dash pot failed on the new one '99 or so. Stole the one off the rebuild and warm idling problems were gone,,,,so was the auto choke. Heard 'klink' and knew something was amiss.
Oh well, i just drove it for fun. Dang i miss that truck. Bit of a hot rod Stock with the 350, Q-Jet and a 3 speed. (old style slot mags and 275/60 R - 15 tires).
Chevy MC was just a copy of Pontiac GP and for muscles the GP 69 could be a had with a HO 428 and for 70 there was a HO 455...more muscles that Chevy ever could dream of :)
The Quadrajet wasn't the only spread bore carburetor I had a Thermoquad on my 340 Demon that was spread bore. If my memory is correct it was 850 cfm. The power valve if set properly kept bit from bogging from dumping all that fuel into an engine at low RPMs.
I ran thermoquads a great bit they were awesome 😎 carbs... easy to work on too.
I invite you to see how a Mexican restores a carburetor in Mexico look for it on youtube as: ¡¡¡ASÍ LIMPIO LOS CARBURADORES!!! SOLTÉ LA SOPA

Your link to the Edelbrock Q-Jet Calibration Kit doesn't produce the kit. I have not tried calling Edelbrock but that kit appears to be missing from the Edelbrock catalogs that I looked at. Nothing from Summit either.
Hello im curious why he said the secondary plates at wide open throttle should be at 90 degrees.
Can anyone explain?
My secondaries are at 80 degrees.
How much play in the throttle plates is too much?
Im not new to wrenching on old cars but im learning about this type of carb so I can rebuild my first one by myself.
Like peoplw have mentioned,there are alot parts in these carbs although some of the parts are cheap because there is so many and they also add up and then you got a good amount into the carb but it's still far cheaper then buying one new or a reman.
I am mechanically inclined so I know I can do it.
I've known about them for many years since I have owned a few cars with them on there and never really did anything with them other than clean them with carb cleaner and drive lol.
I know they call them quadrajunk but I think those are ones who just never really learned how to rebuild one right so they can perform at their best.
Had a 72 Riviera with a Qjet and I loved it. Ran nothing but ethanol gas in it and I never had a problem with that car. Would sit sometimes for a month. Pump the gas pedal twice and turn the key and it fired up the first time every time!
I never ever had any problems with any quadajets I used, except the ccc electronic mixture carbs. Now the Carter AFB on the other hand? Nothing but problems. Replaced it with a Holley 650 and all problems were solved
Agreed. Best carb from the factory, and easiest to tune. Even Dodge used them on their 360 trucks back in the '80s
Hi, whats the carburetor paint you used? Do you know if this paint doesn’t remove with fuel contact? Thank you
Wow, huh? Holley has spread bore carbs also
Hey guys what happens if I back my fast idle screw out all the way and it fell out ?? Do I just crew it back in or is there something in the back that it has to screw into 😩 my Choke isn’t closing now !!! Help someone is there something else it has too screw into ?
