OK, Well I just checked out the intake,and it's great. Now what will I need besides the carburetor?

Sorry but you two are the ones who are incorrect.

Which carb are you getting? If you get the manual choke you will need a choke cable if you don't already have one.

You will probably need to make a new fuel line from the pump to the carb.

Is your truck automatic?
If you so you will want something like this so you can hook up your kickdown linkage

Oh and you might as well get a new thermostat and gasket for the new intake.

Lots of little things to check and address when swapping carbs.
Does you truck have an auto trans? If so you will need the Ford downshift kit. Edelbrock sells this separately. And yes, you do need it for your automatic.
The throttle linkage and trans downshift linkage will require modification. Usually more than just bending and tweaking. I typically find it necessary to do some fab work to keep everything properly lined up. The Edelbrock carb is considerably wider than the Ford carb, especially if you added the Edelbrock downshift kit.
Most likely the throttle return spring will need to be redone.
If you go with the electric choke it needs to be wired, as previously mentioned. Ford used the STA terminal on the back of the alternator for choke power. It is 12 volt hot whenever the engine is running. If the engine dies or stalls the STA terminal is dead. Tends to prolong the life of the electric choke cap.
A manual choke will need to have a choke cable added to the truck. I am not a big fan of the Edelbrock manual choke arrangment.
The fuel line will need to be reworked. The Edelbrock fuel inlet is in a different location than the Ford carb. Please, for your own safety, don't just drape some rubber hose to the new fuel inlet.
Oh, and when you are all done the odds are your stock air cleaner won't fit the new carb. The Edelbrock float bowls and fuel inlet typically interfere with the fit of the Ford air cleaner, and several of the aftermarket filters also.
This is when you stop and ask yourself "Why didn't I just put a stock replacement carb back on."
Not trying to talk you out of the swap. Just want you to be aware of what the swap might involve.
Good luck.

BOTH you and I are incorrect. You said the 1405 is richer; I said they're the same, when in fact the 1406 is richer as shown on Edelbrock's website. See my previous post.

The 400 has a dry intake. The thermostat sits in the block and is not part of the intake.

This is incorrect. The stator terminal of the alternator is an AC signal. In reality it is less than a few volts RMS. If you look at it with a cheap multimeter, it will "see" 6 to 7 volts DC.

I have a manual transmission, not automatic
And as of now I am planning to buy the electric choke, seems to be less of a hassle to set up than the 1405
And I know my original air cleaner will not fit my new carb, that's why I'm buying a new open air cleaner(those should have a pcv port right?)
And besides me needing new gaskets for my new intake, do I need a spacer or something for the carb?
Or just the gasket that comes for it should be good?

There is a lot of information available on this site. Some is very accurate and other bits less so. As with any information on the internet, once it's posted it is there for all to see for all eternity (well maybe not so much here, but anyway...)
I take every effort to be certain anything I post is based on firsthand knowledge, or I can document and verify with more than one suorce.

I stand by my previous comments about Ford using the STA terminal as a sourcs for 12 volt power for the electric choke.


Joel79ford:
The PCV itself does not connect to the air cleaner. The PCV connects to a full manifold vacuum port. Ford usually plumbed it into a spacer between the carb and intake, or in some later applications the PCV line was plumbed directly into the base of the carb. The Edelbrock carb has a large port on the front bottom of the carb where the line to the PCV should connect.
I believe the line you ask about is actually the fresh air intake for the PCV system. This line would originally connected from the oil filler cap to the side of the original air cleaner. Most aftermarket air cleaners include a fitting that can be attached to the underside of the air cleaner base that allows for this hose connection.
On another note, but connected...the power brake booster requires a full manifold vacuum connection for proper operation. DO NOT connect (tee) the power brake line to the PCV line. Your brake booster won't work properly if you do. Run the PCV line from the carb or spacer and route the power brake line directly to the intake manifold.

About the need for a carb spacer. It doesn't sound like you will have an EGR connection, so no need for the EGR spacer. Since the Edelbrock carb has a dedicated PCV port you won't need a PCV spacer. However, that doesn't mean you won't need a spacer.
Set the new carb on the intake and make sure none of the carb linkages hit any part of the intake. Work all linkages through their full range of movement, Choke, primary and secondary. Sometimes a third hand is helpful. If there is interference you will need a spacer to raise the carb above the interferences.
Even if none of the linkages hit the intake you might still need a spacer, or plate. You will need to carefully check the fit of the base of the carb against the intake's carb mounting surface to see if there is a good seal between the two. Edelbrock offers a plate, about 1/8" thick for this purpose. Some of their manifolds have fairly thin carb mounting surfaces and the carb won't make a good seal. These plates seal to the intake and to the carb.
Good luck,

Roger Carter

You are correct that Ford used the alternator stator output to power the factory electric-assist choke. You are incorrect in saying that it is a 12 volt source. As I said before, it is an AC signal, the RMS of which is below 12 volts.

If you still do not believe me, I will connect my multimeter and post pictures to prove it to you. I invite you to measure it yourself too.

im looking at the carb online, and it says that the back of the 1406 carb has a port in that back where the booster hooks up to it
And i cant see a place where it would connect to on the new intake...or maybe im looking wrong..

I'm not trying to get in a pissing match here but I stand by what I said the 1405 is richer

Edelbrock 1406 - Edelbrock Performer Carburetors Details

600 cfm

Edelbrock 1406 Carb

Calibrated 2% leaner than #350-1405 for maximum fuel economy
Recommended for most Performer applications
Has timed and full vacuum ports for ignition advance
Comes with .098 Primary, .095 Secondary Metering Jets; .075 x .047 Metering Rods; Yellow 4" Hg Spring

Edelbrock 1406 Edelbrock Performer Carburetors

Sorry for giving false information about the thermostat though, I'm not very familiar with the 351m/400

I was in error; I apologize. I was reading Edelbrock's website upside down. Thank you for the correction.

Hey guys i had a question, where should my brake power booster rerout to?
On the new carb it has a place in the back where it should connect to, but shouldnt it go in the intake instead? Thats how it is connected right now

I always connect my brake booster to the vacuum tree on the back of the intake manifold. I have never been able to get enough vacuum for my booster when connecting it directly to the back of an Eddy carb.
