1940 Windsor Coupe Triple Carb Manifolds-Which carbs to use?

Recommended Posts

Hi Guys,

New to the forum . Just wanted to share one of my projects. Just completed the intake castings for my triple carb for my Windsor C25 coupe. Just interested to know what members recommend in terms of Carbies to use. Just wanted some feedback , before i start machining them. I will also be casting a duel carb setup for both the 25 and 23 inch block ( I own a few early dodge brother projects).

 

Also any experience with triple setups and what to watch out for would be appreciated.

 

I designed them so there are no flat areas for fuel to gather and have a direct path into the cylinders.

It appears your manifold is set up for double barrel carburetors. Several folks here are using the Carter Webber carburetors on there two carburetor manifolds. These have progressive linkage and work well. I am not sure how they would work on a triple setup. Nice looking manifold.mock2.jpg

Thanks Don and nice setup. I will have setups for both 23 and 25 inch blocks with :

double barrel triple manifold

single barrel twin manifold

 

I'll post up some of the picks in the coming weeks

 

Appreciate the feedback

I like the looks also.  I would think that it would have to be set up progressive.  Way too much fuel dumped if they all worked together.

Definitly progressive

What other changes have you made to your engine?  Different camshaft, valve modifications, change to compression ratio, exhaust modifictions.?  What did you intend to run and how are you going to handle linkage?   

The engine will only suck so much air, whether it enters through one hole or three volume will remain pretty much the same.  There might be smoother flow which all help but air volume through each carb will be a third of that entering through a single.  Jetting will need to reflect the reduced flow through the individual carbs.

Do a search on this forum for Tim Kingsbury, George Asche and the AOK boys, they have a lot of history with racing these engines. Another search that would be good is the Montana Dodge Boys.

On a 40 Ford, I used a triple 97 manifold on an 8BA slightly modified engine.  I ended up blocking off the center carb and ran on the 2 outers, ran much, much better that way.  3 2bbls were too much, but sure looked cool!

 

FWIW,

A 230 cubic inch flathead is about 3.6L, I would be looking at imports with 1200cc to 1600cc and see what they are using for carburetors.  I have an 86 Nissan truck for my daily driver and it has a Hitachi 2bbl carb.  The Hitachi is junk but you can look on line to find weber conversions for the 1600cc engine.  I think three of those webers would get you in the ballpark for the correct cfm and jetting and the triple carb manifold will provide the most uniform fuel distribution.

Langdon's Stovebolt has the Carter/Weber 32's originally used on the 1.6 and 1.8L Escorts.  Work great in duals, I still think 3 is too much.

I do have to say those manifolds look really cool and kudos to you for casting your own!!!  Hotrodding at its finest!  1 question, will the rear carb clear the firewall or heater box (if there is one)?  The Carter/Webers are so tune-able that someone probably could get 3 to work well.  Keep us updated on how this works out.  I for one will be following.

 

My home-made intake but not as cool as yours...

As Adam stated " Langdon's Stovebolt has the Carter/Weber 32's originally used on the 1.6 and 1.8L Escorts.  Work great in duals, I still think 3 is too much" That being said that is a fantastic looking manifold. I have them on my 37 Dodge D5 and have worked flawlessly since installed.

As I PMd we are planning to produce manifolds from mild to wild. The Triples are for the larger builds for some beach/salt flats! . For the 23 inch blocks we'll have twin single and triple single options.  I also have a D5 that I cant wait to start working on .

 

Thank you so much for the advice really appreciate it ......agree with the triple bneen too much for standard/ mild setup.......but do look cool :)

You are designing and producing multi carb intakes, but have not done any preliminary "Carb" research and testing as of yet I take it?

What are you basing the basic designs on the intakes, with no preliminary Carb Data to work around while casting the intakes.

Very interesting, have you designed and manufactured just the tri 2 bbl carb intake to date?

Have you cast or designed and dual or tri carb intakes for single barrel carbs yet?

Have you run any of your cast intakes, on an engine or any road testing to date?

Will follow along and see what develops.....

hi 55,

 

not exactly ..have done preliminary research and just testing the waters in terms of what footprint to machine the castings ..so many options with 2 /3 and 4 bolt setups! We designed them around the mindset of 97s, but want to give rodders plenty of options. Have looked at the old designs and their limitations.

We will be designing anything from mild(dual x 1bbl ) to wild ( triple x2bbl allowing for plenty of cfm on built performance engines) for both 23 and 25s.

 

Hopefully the range will be 

dual 1bbl

triple 1bbl

dual 2bbl

triple 2bbl

 

Have you cast or designed and dual or tri carb intakes for single barrel carbs yet? yes

Have you run any of your cast intakes, on an engine or any road testing to date? no not yet - going to run them on three of our cars 

Will follow along and see what develops.....thank you and any feedback positive or negative would be appreciated. As mentioned we love these ol girls and whether they are built for times on the salt flats or beach sands or just to look fast standing still we'll be happy.

I have 97s outside pair but the middle carb is the original B and B  as I needed it to handle the fluid drive Anti stall feature,seems to work pretty well when warmed up after about 5 minute .Not sure if the gas consumption is much better or worse!

Thank you for putting time into this.  I admire the fact that more people are getting into Flathead six performance enhancements.  I will definitely follow you on your topic here.

I alway laugh when I read guys saying 3 are too much and you want progressive..     Based on what testing ?

Eddy Edmunds made a triple in 1954  a couple of years after Chrysler offered factory dual carbs and headers on Trucks. The total CFM of those

dual carb carter ball and balls exceed 3 of the 2 barrel carbs that Tom Langdon sells.  The difference being they are purpose built for flatheads unlike the carter webers.

 

A few things you likely should read

 

1)   The AoK blog on this topic..  

 

2) Like others said -   contact Tim Kingsbury and/or George Asche.  The make in 

 

my opinion and many others the best in class dual and triple carb setups now.  

I run the triple on my  big block 265 and a small block dual carb set up on a 230.   

There is nothing even close and over the years Ive tried many.

 

 

3) If you go through the AoK blog you will see Tim did a series of articles complete with pictures of various  intakes over the years.  Worth a read.

 

I do applaud you for your effort. As a piece of art its awesome.  As a performance intake  based on what I do know I doubt it performs as good as it looks.

The bowed runners I believe were a pre-war concept for a factory single carb setup. and the bases look too low but only testing would be able

to confirm that.

 

In reading the AoK blog regularly it seems they may have had issues with having theirs cast. Maybe an opportunity to join forces ???

 

George is now 85 I think and Tim's Dad which was a lot of his driving force passed away about a decade ago so I dont think they

are planning on bulding any new designs.  I asked George about an aluminum triple for a small block and he said it wasnt in the cards.

 

Best of luck and keep working on flathead stuff.. love it!

Hi Adam -    I think you really should read the AoK article.    3 carbs are definitely the way to go.  If you want to dial it back with smaller jets or smaller throttle bores  both net

out less CFM sure then to your point the overall less total cfm has merit.    In terms of how the flathead mopar engines work, with 3 siamese intake ports, as the AoK boys explain 

it 3 carbs are definitely the way to go.   Overall better performance, better engine efficiency and potentially better fuel economy.
