I've a Chevy 350 with Rochester Q-Jet, my favorite carb of all time. It came with the engine, no mucking around to tune up etc etc etc. Idles well, good mid-range and those huge secondaries help a lot when needed. I've tried everything else, just not for me.

[@hankjones2975]

Did you ever try that q jet on an aftermarket intake and a mild build? I have a very good q jet on a bone stock 1976 vette and am thinking about heads cam, you know the build. That q jet do ok for you?

[@jamesford2942]

Most carbs with run and probably be a little fat. I was tuning an Edelbrock carburetor for a customer and had it dialed in fairly well. He went to see his friend and was convinced to take the Edelbrock off and put on a Holley. Unless one is using a high quality AFR gauge most people are shooting in the dark for the most part.

[@MuscleCarSolutions]

Ignorance is bliss!

[@robertclymer6948]

My new Holley 4160-3310 750 cfm was set up pretty close out of the box. I did however set the idle , checked air/fuel adjust screws (1 1/2) Wired up the elect choke. Started right up, let it warm up and put my vacuum gauge on it and tweaked it. I fattened it up a tad and am ordering a A/F ratio gauge from Summit also. Will adjust it when I am done with that if it needs it. Thanks Brian (hope that is your name). Just love the solid info you share with us weekend mechanics.

[@MuscleCarSolutions]

Yup. Keep tuning! You’ll find the sweet spot with an AFR. Thanks again for the kind words. Very much appreciated and I’m thankful it’s been useful to you!

[@resistorstudios]

The Summit 600 cfm that I got seems to have worked better than any carb I messed with. I highly recommend it. It worked on a 400+ hp LT1 and slapped it on my buddies 305 and ran just as good with no change.

[@blah9664]

I'm leaning towards the summit 600 for my 318 motor. I've heard nothing but good things about the summit carb.

[@markusaurelius1739]

Just ordered one for my 302. Fingers crossed.

[@resistorstudios]

@@markusaurelius1739 update. The original one i gave to my buddy with the 305. Put it on another car with a new 350 no changes and still fired the car off and idled. Bought a new, drove it around for a while and battery died. has been sitting for a few months. Just got a new battery and 5 year antique plates. Took car around the block, could smell bad gas. Ran great! No issues. The second and first 600 summit carbs work great.

[@resistorstudios]

@@markusaurelius1739 make sure you have total timing set properly and make sure no vacuum leaks and set idle with a vacuum gauge. Dont mess with the rear secondary idle bleed unless you have a lower vacuum lopey cam. Just normal holley stuff

[@ciscohour5884]

I have a summit carb. It’s ok. I’d like to try an Edelbrock.

[@ELDIABLO444]

I'm a quadrajet Man myself but I love the summit carb ( i believe they bought it from Holley who bought it from ford 4100 series ???) But I like the Edelbrock Carter carbs too, please do a video explaining the difference between, AFB, AVS, super quad, etc etc etc I'm a little confused about the difference. Once again a great video and all the best to you and yours Sir.

[@cromm2279]

The Edelbrock are the easiest, especially with someone who doesn’t understand cars. Easiest to tune by far. Many better for racing but for everything 400-450 Ann 800eps down to the 600 are perfect.

[@evanwest1929]

Setting up my Edelbrock was easy. I turned all the screws back and forth until it ran shitty and then fucked with it until it seemed ok again. The electric choke seems like it works when it feels like it so I jammed a pen through the linkage and unplugged it. Now my 302 HO runs great. Smells really rich and blackens the tailpipe. 16mpg in an F250.

[@rockycassiano4756]

I gave you a thumbs up........... BUT. Built a 289 in 1983. A 1965 2+2 Mustang, stock w/autolight 4bb carb. Mods: bore 0.020, 10:1 pistons, 0.060 off the heads and cam: ford motorsport 280/290? or 270/280? Full headers, 2 in. dual exhaust. After mod motor would not idle lower than 1200 rpm. Put Edelbrock F4B intake. Still would die if idle set lower than 1200. Replaced carb with 465 CFM vacuum secondaries Holley and idle went down to 770 rpm. It was the quickest car at Ft. Ord. Crashed the car and motor lives on in 1974 F100. The 465 Holley wore out, around throttle shaft. I've put more than 3 different holley's on it and everyone of them has/had a, 'flat spot', around 1800 to 2200 rpm. The F100 has a tall rearend: 2.90/3.10. Different power-valves only change the location of the flat-spot. Point: I've tried two different Edalbrock carb, 600 CFM and one bigger, and both worked fine on the old F100 with a cam not designed for a 4200 lbs truck. The Edalbrock is way more forgiving when cam is mismatched to vehicle weight and/or gearing.

[@MuscleCarSolutions]

Worked fine and tuned are two different things. One thing that a lot of folks do is just accept what’s bolted on and don’t give much thought to it if the car starts, runs and gives them some level of performance. Without knowing how much they’re leaving on the table, I guess I can understand not wanting more. But boy when they realize there is more to be had, the fun really begins!

[@TheThirdWheel618]

If someone doesn't tune a carb with a wideband first to know we're he's at at idle , cruise , and WOT shouldn't be putting a shot of nitros on anything ... Great vid although on the net it's fired right up out of the Box ....I have a 69 F250 390 with a mild cam DEH 265 and headers with a old 350 holly 2bbl I had to rejet that thing 3-4 sizes it was so lean finally bought a AEM wideband so I know what is actually going on . They run right out of the box usually always leaner .

[@yeahididit9054]

“Right outta the box” is definitely real but it’s more subjective than how you are describing it. To me right outta the box means it will work better RTB than what most knuckleheads could or would do to it. I had a 70 Buick 455 that I was having issues with and I bought a rebuilt Qjet setup for a big Block by a carburetor specialist guy and all I did was set the idle and it worked flawlessly. Idle , tip in , midrange, wide open everything was working perfectly.

[@MuscleCarSolutions]

You’re comparing two different things. On aftermarket carburetors, they’re set with whatever calibration the factory decided to use and it’s impossible to be application specific. As far at the Qjets go, the OE had a calibration for each engine and CFM and they’re very easy to set that way again and work a little better. But it’s still a ballpark for most. Unless your rebuilder asked all the right questions and set the carb up for your specific application. But even then, it might RUN out of the box, but it’s usually far from completely tuned.

[@MikeSmith-cx2dj]

I just changed the throttle linkage placement setting from slot 2 to slot 3 --- way better squirt response at secondary hit .

[@MuscleCarSolutions]

I’m not sure if I can help you. As the video explains, there is no such thing as the best out of the box. You can get it close and get it to run, but there so much more to be had. Sounds like you also need to address the fuel system. My Ultimate Edelbrock Carb Tuning guide has a good expokiantion of a fuel system and what components you’ll need to do it right. I have a separate video on that if you want to learn more and I also have a separate video on the tuning chart. Trust me when I tell you that YOU can tune your carb. YOU can get the timing set right. YOU can learn to be self sufficient with this and know when problems arise that YOU can diagnose it and hopefully fix it. My condolences on the loss of your Dad. Nothing better than to carry on his legacy by continuing to work on your project.

@@MuscleCarSolutions I really appreciate your time I’ll look at that video what jets and adjustments etc. would you recommend for this engine?

And how do I know if the electric choke needs replaced?

[@MuscleCarSolutions]

@@kingarthur7255 the 1406 might be a touch large for that combination. You can tune it down some, but the CFM is on the large side for what that engine can consume. As far as tuning goes, follow the tuning chart. Only you will be able to do that based on how the engine runs and what direction you want to go with it. The videos I mentioned on how to read that tuning chart will give you all the tools you need to understand the process and to get started on it. I wish I could give you a good base calibration but its impossible. Its a hands on thing and you'll be the best person to tell what the tuning steps will be. Watch the video and go download that tuning chart. The electric choke you can tell if its working once you get it on and operating. I did and electric choke video on how I adjust them. Hate to keep pointing you at other video's I've done but its really a good resource to answer your questions. And last but not least, I fully understand the joy of driving on a transmission with a 1:1 final ratio. lol Its awful.

Going up 15 jet sizes on that Holley 800 is not right, you should not have to go up more than 4 jet sizes unless you are removing the power valve.

[@whyidontknow7113]

I personally am an Edelbrock guy. People tend to say that they're great for drop in applications, but it completely depends on the motor. I have a hopped up 400 sbc that came with a stock 1406, and it ran richer than Oprah until I calibrated the primaries. Still need to go through the secondaries.

[@MuscleCarSolutions]

Well, that could be the right size carb if that’s what you’re asking. I did a very good video on how to select the right size. If you watch that you’ll be able to confirm if that’s the right one or not. As far as tools go, getting the fuel system right is far more important than any speciality tool you could use. Is an AFR gauge a great tool? One of the best there is! Do you have to have one to tune, not for most street applications. The how to set up a fuel system video I did has great detail on this. Check that one out and see how it compares to your set up. If you have the fuel system right, tuning goes so much easier. As far as bolting on a carb and not doing a thing to it, I don’t doubt in some cases it will run. But there so much being left on the table that can help power, maintenance and even potentially a little bit of fuel economy.

I just installed a 4 barrel 650 cfm Edelbrock carburetor in my rebuilt Chevy 283 engine. How can I find out what adjustments if any are needed? How do I know if it’s burning too rich or not etc..,

[@MuscleCarSolutions]

I’m going to assume it’s very rich. Even on a pretty aggressively built 283, that’s a lot of CFM. First watch my video on fuel system set up. There are some critical and important pieces to that system you’ll want to have and in the right order. Next go watch the video on the Edelbrock tuning chart. Will give you all the information you need to start making adjustments. Remember timing is part of tuning a carburetor. Before you even touch the carb, verify the timing is appropriate for your combination and elevation. I start at 12 initial and go up to 18 to find the right start to your timing. You’ll come back to it again. Fuel and spark are tuned together. Then start the process.

[@petecunes7143]

Is having that 650 cfm going to be problematic in the future or even now? I mainly drive my car on the weekends. I’m not very mechanically inclined. I know the timing was set when the carburetor was installed.

[@MuscleCarSolutions]

Don’t know. Your setup will dictate the size of the carb. If you watch my video on how to choose a size, it will help you determine what size you need and what the engine is capable of using.

You’re not going to find the solution to more torque/hp in a carb swap. Especially if you’re out working the capacity of the truck/engine.

[@MuscleCarSolutions]

I have a good video that will answer that question as I can’t without more info. If you look for How to Choose the Right Size Carburetor on my channel, it will walk you though. I can help you confirm with the additional info needed. Just watch that video and you should come up with the right answer. As far as the regulator goes, it’s a great decision to run one. I prefer a return back to the tank as it keeps the fuel moving and not sitting near the hot engine for too long. If you want to run that style or the non return (deadhead) you’re still going to get mostly the same result. That level of adjustability in the fuel system that you didn’t have before.

What AFR meter do you recommend? I have a Edelbrock 1405 on a bone stock ‘78 440 in a 3/4 ton truck with auto trans. It never really sees even 4000 rpm, and tach tops out at 5000. I have it running fairly decently I believe, but would like an affordable (hopefully less than $100) AFR meter to confirm that. Thanks.

[@MuscleCarSolutions]

You might find a narrowband AFR that is that cheap, but the feedback in limited with that style O2. I have a video on the difference in those if you want more detail. Honestly with a stock set up, I would be hard pressed to spend the money on a gauge. I can understand wanting to know to help fine tune, but I’m not sure how useful it would be. If you have it running well, I’d likely leave it be.

[@SteelSurgeon]

@@MuscleCarSolutions Ive been watching a couple older used meters on ebay Just have a hard time dropping the money for the reason you listed. It does run fairly well. Changed the springs out, though I cant remember which ones I have in off the top of my head and changed to the highest hole on the accelerator pump to get past an off idle stumble and that worked. Also changed the rod to fatten it up a bit on the higher end. Jet is still as it came from factory. It seems to run out of gumption around 3-3500 rpm but i dont know if its because I need to change to a bigger jet or because I limited myself to the 600 cfm carb. Your opinion? Im relatively new to automotive carbs. Have messed around with tractor and small engine carbs for a long time but the automotive ones throw me for a loop sometimes.

[@MuscleCarSolutions]

@@SteelSurgeon for sure you might be limited a little by the size of the carb, but it’s the operating rpm of the engine that will limit the need for a bigger carb. It’s just not needed. I just did a video on selecting carb size and cover a lower rpm application like yours. I would continue to tune, make sure your ignition/timing is right and you should continue to see better results. For sure the AFR would be helpful to use on this situation. Cheapest one I’ve used in the past is in my ultimate tuning guide video. Works well. I think at the time it was around $150.

@@MuscleCarSolutions Hi thank you for the response new fuel filter was part of the trouble shooting yes. Timing is at 14 degrees BTD manual fuel pump no fuel pressure gauge. The edelbrock 1406 I have has been working good for the past 4 years but all of a sudden on Monday 6/21/21 everything went south. When i took out the needle seats there was small peaces of white plastic on both of the little fuel screens on the needle seat valves that was yesterday when i took it apart.

[@MuscleCarSolutions]

@@akbound.prepper5676 keep digging. If you had crap in the carb it came from somewhere. Not much more I can suggest. I’d try to track back and see what that plastic is. Sounds like it could be the root cause. On a side note, check out my video on how to properly set up a fuel system. A regulator will help and give you another adjustment point in a system that’s limited.

My eddy 600 ran great right outta the box on a junkyard 360 , little timing and pilot adjustment , chalky brown spark plugs daily driver but it's luck of the draw .

Ive NEVER had anyone come my way cause ther edelbrock wouldnt run ! My old neighbor had a like 65 mustang . 289 4 speed . Garage talked him into a holley . And then couldnt make it run . Went to another garage and they told him he bought the wrong holley . Buy this one . He did . And they couldnt make it run either . Guy barley made it home . Herd him strugglin . Car was flooding horribly ! He asked if i would help . See ya workin on cars all the time . I told him , sorry i wont work on your holley . Ive throwin probably 30 plus holleys in the garbage . Got a edelbrock you can try . No no he says . Gotta figure this out ! Well i only know one guy that likes snd runs holley carbs . Sent him up ther . Guy tells him , you bought the wrong holley ! So the poor smuck bought a third holley . Seen him a cpl days later . Howd that work out for ya ? It didnt he says . Cars bareley running he says . You drive it he says . Ok . Soon as you gave it any gas at all it would stall bad ! Couldnt even buzz it up in neutral . Fall on its face ! Told him again . I got a edelbrock off my 390 . It was a good carb . I know it works ! Ok he says . Took about 20 mins . Had a edelbrock bolted on . Fired it up . Waaaaay happier 🤔 Test drive , you drive he says . Ok . Little 289 layed down about a good 30 foot patch rubber ! Were side ways pullin out on the highway ! You got a posi i told him . Geuss so ! The cars never ran like this before he says ! Dam little 289 hit 128 mph ! In 3rd gear ! The guy was burning a tank a gas every 2 n a half days with the holley to work and back . Guy drove 2 weeks on a tank a gas to work n back with the edelbrock ! And laid rubber doin it ! Guy called me Mr Edelbrock fr the next 2 years till he moved lol What do i do with these 3 holleys he says ? Personally i throw em away ! Craigslist maybe ? They say thers a sucker born every min!

Hey great video very helpful I have a question whats the typical carb I can use for my stock 454 cruiser it got a 1406 edelbrock right now thanks

[@MuscleCarSolutions]

That one could work but it depends on the situation. I’d watch my video on How to Choose the Right Size Carburetor. You’ll get the variables needed to see if that one is the right size for what you’re doing or not.

[@starcloakstarside9719]

Contrary. I’ll tell you what. My Edelbrock 650 was NOT perfect right outta the box going on my 302 Ford small block. Not obviously that’s at least 50 CFM bigger than that engine should be able to handle, but as far as that being the only reason it wasn’t perfect, a little trip to the Calibration Kit fixed that right up. And now my ‘82 Bronco makes a buck 10 in about 12 seconds fairly easily. It’s freaking great!

[@MuscleCarSolutions]

Yup. Everything has to be tuned. It’s really amazing how many people just bolt on a carb and drive it without giving the tuning side any thought. Then they complain the carb is junk. lol Have fun with the Bronco! Love that body style.

[@jonathanlawson4667]

Yeah they'll throw it on and it will flood or the gas mileage is horrible and they'll complain that it's the carb 🤣🤣🤣there's no competition between these two they both are great carbs

[@markmccarty9793]

A 302 in an 82 Bronco hitting 110 in 12 seconds?? Huh!

[@starcloakstarside9719]

@@markmccarty9793 Fair. It’s a supercharged build (positive displacement and pulley ratio pushes 560 CID by 2,500 RPM), running a nasty cam, new rotating assembly, new heads, (or, was new when they were installed anyway), technically it’s bored .030 over to 306 CID Natural, 3,800 RPM Stall Torque Converter, tachs out at 8,000, but it’s still got the original 302 block. Not a single part inside of the block is stock, and I even went ahead and TIG welded some extra bracing in up in Lifter Valley to keep her from splitting in the higher power ranges. Very hard to do with cast iron, but my metallurgy has always been solid work. That outta the way, I can see where the confusion lies. Barely believed it myself, swapped a blown 460 build in a time ago and then went back to the 302 because it actually ended up being faster with weight and fuel distribution factored in. Edit: Additional. I’ve since gone to a 750. 650 ended up choking her out after about 140 MPH. Currently putting proper wheelie bars on her because she does try to flip backwards on a hard pull. I swapped the gearing on the tranny myself awhile back along with throwing a trutrac in the front and rear diff, not to mention I built an overdrive gearbox off the T-case with a manual engagement for better highway fuel economy. Suggestion. Keep your eyes pealed sometime in the next coupla years for a Cream an’ Blue ‘82 shitbox Bronco doing a standstill 4x4 burnout somewhere in the Lower-48 if that’s where you’re at. Flag me down for a keg of beer and a ride if you see me! Edit: Disclaimer. Not in that order. Hahah!

[@JAIME101329]

I got a stock 350 block with a Edelbrock performer rpm top end kit. What size Carburetor should I use?

[@MuscleCarSolutions]

Hard to say without any more info. As a guess, the 650 AVSII would likely be a good choice.

[@theedge5584]

How do people use 750s n up on a stock motor......It is to much

[@MuscleCarSolutions]

Look at images of a quadrajet or thermoquad carb. The primaries are small. It’s where the engine operates most of the time and they can be calibrated to flow the amount of fuel needed for that engine in a vehicle that isn’t seeing high rpm. That’s how the factory does it and makes one size carb fit a lot of different applications. On an aftermarket set up it all depends on what the combination of parts is, but over carburating is a common problem. Bigger isn’t alway better.

Why would you change a performance carb unless you are prepared to fine tune it ?

You’d be surprised how few carburetors actually get tuned. Idle mixture screws and idle speed and that’s it for most. That’s the extent of their “tuning”.

[@jesuscobos7243]

You dont need a pressure regulator when you have a mechanical pump , or 2 filters , just one between the pump and the carb (to the best of my knowledge)

[@MuscleCarSolutions]

Absolutely you should. Several a reasons why. Stock, off the shelf pumps don’t always put out the pressure they are rated at. Having a regulator and a gauge allows you to verify what pressure it’s pushing to the carb and adjusting from there. As a tuning piece, there are plenty of times in the process where dropping or adding pressure helps to fine tune the system. Hotter climates with an ethanol based fuel might like a bit more pressure in the system. A regulator allows you to set that. It’s an analog system. Giving yourself one more adjustment point in the system is never a bad idea. Every fuel system I build, no matter what pump I use, gets a regulator and a gauge. Same goes with filters. 100 micron to stop the big stuff and a 10 micron to stop the small stuff. Having two helps keep the fuel pressure consistent. Having only one filter can restrict the system. Delivering a consistent amount of fuel at a consistent amount of pressure gives repeatable performance.
