How to install the Edelbrock 1406 Carb

[@AlfsMustangGarage]

I'm normally a big Holley Carb fan. But lately I've been using these Edelbrocks. I think they are great for a good daily driver/cruiser 👍

[@AndyKruseChannel]

I don't understand all the hate towards the Edelbrock, and I've had this same carb now on all three of my Mustangs. I would like to try the other side of the fence and see if it's greener over there. :)

[@AlfsMustangGarage]

@@AndyKruseChannel lol yup! At the end of the day, it's delivering the fuel to the intake. I just like the tuneability of the Edelbrock. I can change jets and/or metering rods without removing it or making a huge mess of fuel. I grew up with Holley carbs so I have my appreciation there too. But no these are fantastic carbs as well.

[@Izvitoy]

When I bought my 66 a month ago, it came with a 1406 on it. Nice to see its a good choice

[@AndyKruseChannel]

The 1406 is a popular Carb for our cars, particularly because it has some head room for engine upgrades, and offers an electric choke. However, it's tuned from the factory for economy and emissions control, which is why I modified it to be like its "performance" brother, the 1405. :)

[@randypascarella]

Schweet! I have the same carb too! I know nothing about Edelbrock carbs, didn't realize it was tuned for fuel economy, thanks for skoolin' me! Also, I bought the Summit Racing SUM-G1532 inline fuel filter/line for it, thinking it will help in keeping the inlet in front of the carb closer to where the original Autolite carb had it, but I haven't gotten far enough yet to hook it up. I'm stuck trying to finish detailing my engine bay until the weather warms up! Thanks again for your helpful vids, I learn something every time!!!

[@AndyKruseChannel]

Awesome, thanks for the support! Now you know how a little more about that carb, you can give it a small bump in jet and rod size and see if the car feels a little snappier. :)

[@SmackeysGarage]

Always fun when you are missing pieces to finish a project. Happens to me almost every time! What's your plan for the fuel lines? AN, stock metal, or rubber?

[@AndyKruseChannel]

Solid fuel line from the pump to the carb, but that'll be a separate video. :)

[@carlosn586]

I have this same carb on my 66 mustang. How did you plumb the PCV? I purchased the stock bent hose only to realize that Edelbrock has PCV to the front of the carb not the rear. The valve on the valve cover is 1/2” but the port to the carb is 3/8”.

[@AndyKruseChannel]

I used some heater hose to route from the PCV on the valve cover to the front of the Carb, no big deal. :)

[@seanturpin6066]

Do you run the one fuel filter from the pump to the carb or have a secondary.

[@AndyKruseChannel]

I don't have a secondary filter, but someone could add it if they wanted. :)

[@markcernicky5335]

please tell me what video follows this one: finishing this one ? i'm trying to figure out how to plumb distributer vacuum advance with new manifold? THANKS!

[@AndyKruseChannel]

The vacuum advance line from the distributor goes to the carburetor, not the intake manifold. On my Carb it's the port on the left hand side (if you're looking at it from the front of the car), and it's called the "Timed Vacuum Port".

[@sonnyskustoms]

Hey andy thanks for this video, i am setting up my 1406 on a performer also i installed everything accordingly but my vacuum source i didn't get it from the pcv valve i got it from the manifold behind the carburetor and it seems to idle pretty funky, i tried to do a snap acceleration in park and it almost wants to stall i have to gently eas on the gas so it does shut off, Also i didn't put the gasket spacer you have on the video so probably i might have a vacuum leak maybe? Or could it be a bad accelerator pump? I bought the carburetor used so i installed it just like that, is there something im missing? Thanks

[@AndyKruseChannel]

Yes, you need a gasket between the carb and intake manifold. Vacuum leaks can cause the bogging you are referring to, but so can other issues. You might need to buy a rebuild kit if you don't know the status of the used carb. :)

[@CartoonDrawingStudio]

What about transmission throttle linkage at the bottom ? Does anything have to be done with that when upgrading from a 2 to 4 barrel carb

[@AndyKruseChannel]

Cartoon! One of the early subscribers here! Are you referring to the kick-down linkage for Autos? If so, you'll want to keep that linkage and it may require a custom touch to make it work with whatever Carb you choose.

[@CartoonDrawingStudio]

@@AndyKruseChannel thanks Andy. I have a 66 and I basically follow your lead. I upgraded to edlebrock 4 barrel intake and carb. I have a C4 trans for now, but I noticed there is slack in the kick down linkage with transmission. I will take a look at adjusting. Thanks for your content it’s so helpful!!!

[@ronwatts268]

I'm upgrading to an Edelbrock on my 65. What throttle linkage part did you have to get?

[@AndyKruseChannel]

Back when I had that Carb, I ended up threading the end of that linkage and installed a nut just to get it to work, so I could drive it. I would not recommend that today, in fact, I now sell a Throttle Linkage that would bolt right up to and remove the issue I created back then. You can check it out on my website KruseBuilt if you're interested. :)

[@paulfragoso7006]

Hey do you have a picture of the side view of the carb? On the side with with pedal link

[@AndyKruseChannel]

Sorry, I don’t have that carb anymore.

[@StankyPete9]

Hey, Edelbrock brothers! Running a very similar setup, intake and all (performer RPM and AVS2)! I got a manual choke though, and now and I'm wondering if that was a bad choice. I don't have to mess with it ever really, but electric would probably keep it optimized! I hear people singing praise for Holley all the time, but I've never had a problem with my Edelbrock equipment! Runs well enough right out of the box, and tuning was breeze! Another great video!

[@AndyKruseChannel]

Thanks for the feedback! Having that manual choke isn't all bad, technically one would still need to dial up or down the choke on the side of the Carb for colder weather. Because of the winters we get here that car hasn't left the garage since November, so I don't really mess with the choke much.

[@torreerrot]

Cool. This video came out just in time. Tomorrow I am about to give a good clean to my 1405. For some reason, it's not spraying gas... I think it might be the pump, but I am not 100% sure. I know gas is going in, but not sure if the reservoirs are getting filled. Once I remove the top I guess I will be able to see what the problem might be.

[@AndyKruseChannel]

Awesome, Good luck!

[@Sensei314POKE]

Such a great video! Thank you for sharing your wisdom

[@AndyKruseChannel]

Glad you enjoyed it!

[@bofa83]

Why do you need that spacer on there?

[@AndyKruseChannel]

The biggest reason is to keep the Carb from getting heat-soaked by the heat carried through the intake manifold. It also provides a little space under the carb for routing things like the heater hose, wiring, etc without needing to cram things in place. :)

[@lucasvanvondel7347]

Do you have to adjust a lot on those carbs when you buy them new?

[@AndyKruseChannel]

Yes and no. They'll work right out of the box, but the idle mixture screws and throttle adjustment screws will need to be dialed in after you install it. From there you'll want to adjust the choke (if the carb has one) and then you can dive into the Jets and Rods. :)

[@darylsearle3474]

CAN I RUN THIS CARB ON STOCK MANIFOLD?

[@AndyKruseChannel]

I believe you can, I believe you can purchase an adapter that bolts to the stock manifold and has the bolt pattern for standard aftermarket carbs like this one in the video. :)

[@nathannelson7020]

Another great video, I gotta give you crap for not putting a Holley on...haha. A consideration, instead of using stock throttle linkage, use a scott drake billet one part # C5ZZ-9A702-BL. Put it on my fastback gives it a slight custom look and doesn't require all the other small parts the stock one does.

[@bofa83]

Am I imagining it or did you say in a video that you had issues with the carb and had to put the stock metering jets back in?

[@AndyKruseChannel]

A while back I swapped the jets and rods back to stock because I was finding that the upgraded ones I put in were a pinch too rich for my liking. I didn't have the sizes that were between the stock sizes and the upgraded sizes, so I just put them back to stock with the intention that I'd get back in there and tweak them again. Since that time, I had decided to do the 347 build and I figured that I'd need different sizes again, so I just put a pin in it until the engine build was finished. :)

[@toddzukowski9083]

What part did you have to order to make the stock pedal linkage rod work? Does it not just go where you have it in the video?

[@AndyKruseChannel]

At the time I made this video, I thought there was a piece I could order to connect that stock linkage piece to the Edelbrock Carb, turns out I could not. In fact, the video I made right after this one was making a custom throttle linkage since I could not easily make that stock one work. :)

[@AndyKruseChannel]

@@bucky0868 Those three ports each have a different job, but important in their own way. All three are vacuum ports, and none of them should be left open as it will greatly affect how the car runs. The easiest port is the center port, and it's most common use is to connect it to one of the two valve covers for the PCV (usually the passenger side). The PCV is the Positive Crankcase Ventilation, a quasi-emissions control device that pulls vapors and pressure from the crank case. In the video I didn't have that specific hose and new PCV, but I have since added it, you can see it in later videos. The port on your left hand side of the carb is the "Timed Vacuum Port". It's mostly for vehicles with distributors with emissions controls. I don't think I've seen anyone use that port for cars like ours, but somebody probably uses it. The port on your right hand side of the carb is the "Manifold Vacuum Port" and this is the one you want to connect to your vacuum advance port on the distributor, if you're using the vacuum advance mechanism on the distributor. Some people don't use that feature on their Distro, so they just cover that port on the carb. That spacer has some additional benefits, but they're minor. One, that plastic spacer isolates the carb from the intake manifold that can get hot. A hot carb will run less efficient that a cooler unit. Also, the spacer adds another inch of "runner length", potentially creating a pinch more torque, but I cannot verify that, it's just what some manufacturers have done with more modern cars. And lastly, the added height, which may or may not help in your setup. :)

[@PatDaddi]

Hey Andy! Thanks for the video. Curious where you wired your electric choke?

[@AndyKruseChannel]

I added a relay that was triggered from the Ignition terminal on the starter solenoid. It is probably overkill as the choke doesn't pull many amps, and not everything needs a dedicated circuit, but I like it that way. I made a video on it, check it out! :)

[@boniebuhr9928]

Hey Andy. Have you considered fuel pressure regulator or?

[@AndyKruseChannel]

The 1406 is on the cusp of too large for the 289, even with simple bolt-ons like intakes and exhaust. If someone were to do more, like a cam, then this carb begins to be something that will work great. I haven't done anything else engine wise, yet...... :)

Awesome video, watched and rewatched this one today during my install. Have you had to deal with a hot air choke tube coming off the exhaust manifold?

If so, how did you do it? Thanks!

[@AndyKruseChannel]

Thanks! My first mustang had that tube, but I damaged it before I realized what it was. If you have this Edelbrock carb, you no longer need that tube as the electric choke will do the work that the original choke and hot-tube were doing. You can just cut it off the manifold is it's all rusty down there, otherwise, I think it just pulls out of the manifold. :)

Hey Andy, what kind of carb spacer did you use?

[@pieroramacciato9434]

Why did you want this to be like a 1405? More HP/performance over fuel efficiency? I got a 67 Pony with a 289 2-barrel in March. New to this hobby. I like the detail of your vids. Thanks

[@AndyKruseChannel]

The 1406 has an electric choke and is tuned towards fuel economy. I think it has something to do with California Emissions Legal something something. For me, it was easier to get the 1406 than to buy a 1405 and buy an electric choke kit. I definitely want the electric choke because of the temperature delta through out the year in my area. These days fuel economy almost sounds more interesting than extra power, but since I rarely drive the car, I'd rather have a little more punch than an extra 2 miles per gallon. In another video I replaced the Jets and Rods with the same sizes found in the 1405, but a while later I ended up going back to the stock 1406 sizes (car was running too rich). I could have found sizes in between the 1406 and 1405 sizes, but I figured I'd deal with that later. I think my biggest issue is that the 1406 (600cfm) is too large for a relatively stock 289. Even though I have an upgraded intake manifold and complete exhaust, the 1406 is too much for this motor. A 500 or 550 cfm unit would probably be a better fit.

Without that black phenolic spacer below the Carb, yes. If you wanted that spacer, you have to get an air filter with a "drop frame", where the bottom tray of the filter is shaped to allow a 3" tall filter without sacrificing something like the hood. Also, the hood scope on this hood is purely aesthetic, the previous owner grafted it onto the stock hood and never cut a hole for air flow, so you could use my hood as a gauge on how your setup my fit. :)

@@swooshdave The 1405 Carb has manual choke and is tuned more towards performance from the factory (although further tuning is usually required). The 1406 has the same 600 cfm as the 1405, but it has an electric choke and it is tuned for fuel economy (leaner) from the factory. The changes I made swapped out the rods and jets from my 1406 to the same units used in the 1405, which gives the Carb a slightly more "performance" tune right out of the gate. I will need to further tune my Carb to eek out every last bit of power, but I'm waiting until I decide where I'm going with additional performance parts. If a guy did the same changes I made to the 1406, and also swapped in an aftermarket intake and headers, this setting I put the Carb at (which is the stock 1405 tuning) is a great place to start.

@@swooshdave There are charts out there (called the calibration reference chart) that show the tuning for each Carb, with the center being the stock Jet and Rod sizes.

What I did was change those out for the stock sizes of the 1405 which is 0.100" for the Main Jets and 0.070" x 0.047" for the Metering Rods. Now that my Carb is sitting at the factory tune for the 1405, I will continue to use the 1405 chart as I work my through the tuning process. Other than the electronic choke and the factory sized Jets and Rods, the 1405 and 1406 are identical Carbs. This is how I can safely and reliably use the 1405 tuning chart and I move forward.
