good point.  I have some other carbs I can use.  The 4100 has the simplest top and I thought if somone had one beyond repair than maybe.

As many of you know I am modifying a throttle body to fit on an edelbrock 4-barrel intake.  As part of my plan I want it to accept an air cleaner housing just like a carburetor.  To that end I need the top from a scrap 4100 to adapt to the throttle body.  Anyone able to hook me up?

I ran a die over the 1/8” pipe thread on the fitting and converted it to 3/8” fine thread. I will use a little RTV on the threads however I don’t think it’s actually needed as the fitting is tight. I have done this before and gotten a perfect seal with out any sealent. I thought it was kind of odd and was wondering why you were asking about pipe thread. Makes sense now. 😀😀

You guys crack me up.  I was pleased at how well the throttle body was going together and expected more thoughts on the project, concerns and what not, but you guys are totally side tracked by the home made tool. Thats hilarious.  

Hit a small snag.  Went to install the fast idle air control valve and realized it was going to stick up to far past the opening and hit the 1" spacer on the bottom.  I quickly realized that if I turn it upside down and make an 1/8" spacer to go between it and the throttle body everything will clear. crises averted.

I still need to fabricate a top plate so the air cleaner has a place to sit/attach. I will post more pictures when I get that part done.

Your handiwork is always impressive.

 
That’s an idea I came up with quite a few years ago. They’re really easy to make and they work really really well. You never have to worry about stripping out the first few threads or the threading going in crooked. Anytime I have a new size that I’ve never made before I make one. In fact I had to make the one for the 5/16 stud holes as I did not have one in that size.

I have been gathering parts to convert the 302 in my Galaxie to EFI.  I built a MegaSquirt ECU 5 or 6 years ago.  I also gathered up the modern upper and lower EFI intake but I don't think I have clearance between the top of the modern intake and the hood so I am planning to drill holes in an edelbrock performer intake and add fuel injector bungs (already have a nice set of rails).  I was trying to find a throttle body but they all are big $$ so I decided to take the modern throttle body and adapt it to look like a carb, use a carb air cleaner and mount to the edelbrock intake.

here is the foxbody throttle body and a 1" square bore spacer

I started by drilling a vacuum port.  I drilled out a 1/16" hole all the way through, enlarged it to 5/16" wide 1/2" into the spacer and then drilled two more 1/16" holes at an angle

As you can see from the gasket on the spacer, the throttle body is about a perfect fit on the square bore

I then marked and drilled the holes for the studs.  1/4" holes and 3/4" deep so they didn't go all the way through.

I once again used another home made tool like before, I call it a “square tap” as it makes the tap square to what you are tapping as you use it.

Its the RPM where it builds on it self.  there is a sweet spot where it seams like the drone would continue to get louder and louder with out changing RPM  that is the all important #.  So I guess the answer to to your question is yes its at the loudest point

I have not yet gotten around to rebuilding the carburetor I have to do a real test.  I have sent out two sets of these to other people to test (4-5 months ago) and have never herd back from them.  This project is stalled until I either find the time to rebuild the the carb I have or unless I hear back from those that said they were willing to test for me.

I see you mentioned the length of the lever having much to do with the turning radius speed,  does the length also have anything to do with the force needed to turn?   How does that all compare to LTDII or Granada spindles?  Dont go out of your way to find out, just curious if you have measured those spindles to compare.    

Nice work btw.

Thanks!!

The LTD II spindles have the same geometry as the galaxie spindles (thats what I have on the car now and the same steering arm length)   Granada spindles have about the same steering arm length might be about .5" shorter if memory serves but the Ackerman angle is different.

Just thought I would share the post I have made on a thread I started on my galaxie forum.

I am working on modifying my steering arms to correct the reduced turning radios after installing home built R&P setup. 

In the long run the arm will be cut from angle iron but as I design it I will probably make it out of wood. (more to come)  I think I have figured it out and  have started the process today of building a fixture that will locate the OEM mounting location and orientation.  I need this so I can completely cut off the original arms to get them out of my way as I design the new arm.    Best part is  I think I have a fixture design that can be used for both sides by making it two piece and bolting the two pieces together I can remove the pieces reverse them and bolt them back together.  More to come as the project develops.

You need these points to insure the correct Ackerman angle.  Ackerman is what allows the inside tire (when turning) to turn more sharply than the outside tire.  Ideal Ackerman (not all cars use ideal Ackerman) is calculated by drawing a line from the spindle pivot to the center of the rear axle.  

http://dazecars.com/dazed/Mustangsuspension/ackermanangle.jpg

As long as the tie rod mount is some where along that line than Ackerman will be correct.  The closer it is to the spindle pivot the quicker the arm will turn and the further away the slower.  In my case I have less steering travel so will need it to turn quicker. Before starting I used a piece of string and confirmed that the Ackerman angle on my car was ideal.

Once I had the two points I took the jig apart and located where the new tie-rod loc

I received a PM that I thought others would be interested in:

Daze
Thank you for your information on carbs! Can you help clarify an item. It is my understanding that Hipo mustangs had 1.12 Venturi's but a different primary. This is what gave the horsepower without sucking all the gas! Otherwise it's very inefficient. Seems by reducing the Venturi you made a 1.08 but would still have the issue with the primary?
Thank you!

Besides sleeving I plan to change jet size and boosters.  The smaller venturi will allow for better throttle response.  I have also purchased smaller jets for my carb, I went from 55/64 to 48/55.  the third piece to this puzzle is the boosters.  The ones that came on my carb, especially the one from the secondaries has huge booster tubes.  I plan on first trying it with these boosters and then I will swap them out for a combination of boosters with smaller tubes.  I got two different booster sets off of a some two barrel carbs I had for parts.  It will be more trial and error than exact science but I think if I go with the smallest booster I have in the front and the next biggest in the back I can probably get it close.

Ok finally an update.  I have not yet had time to rebuild the carb that is my test platform however there is someone on this form that has a 4100 ready to go so I am sending him a set of inserts to test.  The final design is very short but still hangs down far enough to be a snug fit in the bore.http://imageshack.com/a/img923/6868/UYI8gU.jpg


The fluting on the top has not changed and they look just like the ones in the picture I posted earlier, and again below.

When you say the size of the openings are you referring to the physical dimension of the booster venturi itself where the annular fuel discharge holes are housed?

I am referring to the holes on the under side of the main booster body next to the tubes.  In this pic I borrowed from the net it is the hole that is under the vertical arrow.

Your thread got me excited about these carbs again and I've bought two more rare/ unique 4100's since you've posted and have done some more measuring- you bad influence!

I have a few Edsel 4100's from '58 that have 1.06" primary venturi size, thats the closest in size Ford produced to what you have. I could measure the booster orifices with precision for comparison should you decide to really play with the fuel curve.

That's me trying to influence you ;)

 this project is going along all be it slow.  I got some size 48 jets to put in the front and I will move the original 55 front jets to the back.  I have the rebuild kit and the "bugs" worked out of my inserts.  now all I need to do is get all the parts cleaned up, an put it all back together. 

As to messing with the boosters I think I have a plan there as well.  The openings for the primary boosters are small but the openings for the secondary boosters are huge, they are labeled B and C with B being the bigger one from the secondaries and C being the smaller one from the primaries.  I also have two other autolite carbs that I collected over the years, both are 2 barrel.  One came from a 69 pickup with a 360 in it and the other was the carb that came on the 352 that was in my galaxie when I got it.  I have pulled the boosters from both of those carbs and one is stamped AA and the other is stamped D.  Both have smaller openings than the the B booster from the 4 barrel carb's secondaries but are slightly larger than the C booster.  What I think I will do is run the 4100 as it came from the factory (with the exception of smaller jets) after I finish the rebuild.  I will then install the inserts and see what kind of a difference they make in performance.  After that I will swap out the secondary booster for one of the smaller ones and see if the carb functions even better.

funny thing is this is

Daze, is your 'die' such that you would be able to turn those reducers out in mass?

 
Yes that is the plan, but only if I can meet the following criteria: first it has to work and work well, I won't sell them if it only sort of works. Second I need to be able to make them quickly and easily and still be a quality piece so that I can keep the costs down. I like all my products to be as affordable as possible.

After several different changes to my die and a couple of different adapter designs I now have what I think is going to be the best adapter I can make with what I have, spreadbore adapter 2.0.  These insets have more of a flair to them and they match the contours of the carb body better.  They are also shorter which means it doesn't need to be notched to clear the tube, and the shorter sleeve has less change to the shape of the original carb bore.

The sleve on the right inside the carb has been worked to have a smooth transition but the one on the left still needs to be  feathered.

Perfect those inserts and you might just make a small fortune selling them!  

That is a long ways out but is somthing I thought of when I first started this project.  if I can make it simple enough to work well in most applications than its a go.  As I was flaring the pipe I came up with a custom die design so that I can make them all the same.

Will you use any locktite on them once you make a final determination as to their suitability?  Being an AutoLite fan, I'll be anxious to see the outcome.  Are you going to be able to make any comparisons of the boosters?
 

I really dont think Locktite will be needed. With the lip on the top and the vent tube in the bore there is no way for the part to drop down into the bore, and with them being a slight press fit I don't expect them to work up and out.  When I installed them I was able to press them in by hand but once fully seated I had to use a brass punch and small hammer to get them back out.  As to the boosters I have nothing to compare them too so I really can't say what the differences are.

Jon Richard, Thanks for posting the pix!!!  I searched the net hoping to find pictures (why reinvent the wheel) but never could find anything.​

Thanks!!  its hard to tell in the pix but the leading edge is actually feathered.  Its angled to match the carb and then the inside lip is rounded off for a smoother transition.  I polished up the copper after I shaped it and the flash off the polish is what is making it look more like a normal lip.
