*** note:   Hang in there and at the bottom  of this article, you will be asked if you have any interest in a potential new product.

 

For now over 30 years we have been making AoK  Triple carb intakes  for the  25 1/2"  Canadian 

flathead engine,   found in  Chryslers from 1937,  Desoto's from late 37/38,  and  Canadian built  Dodge /Fargo trucks,  Plymouth,  Dodge cars

since 1936.  Prior to that George Asche has been making triples from factory intakes from both the American  23 1/2" platform, the  American 24 - 24 3/4" platform

and the Canadian 25 1/2" platform from the early 1950s.  As well renowned  performance intake manufacturer made a Triple carb intake for the 25 1/2" motor

starting in 1952  and of course when Chrysler came out with the optional factory dual carb, dual exhaust options on trucks for the 25 1/2" platform, almost immediately

car enthusiasts were trying to put them on cars.  Of course the governors and balance tube made it tough to get under the hood but they made it happen on stock cars and I will attach a picture of the factory intake and then the  "modified version" that was used on a vintage stock car.

 

For all of those   Air cleaners are always a big topic.     Air cleaners for both cosmetic purposes and  of course for functionally removing dirt from the air become the 

reason, but in many cases the challenge is to get them to fit in the engine bay.

 

Lets start with my 1949 Plymouth, which is a Canadian built car that came from the factory with the 25 1/2" motor, and when we put the Aok triple on it.

 

The 1st two pictures was the very day that was done and joined the "what air cleaner can I use club"

So I measured from the firewall to the middle of the carb.  You can see that picture here and the paper was because to cover the hole  where the

cardboard air duct  had been.

Like lots I looked at  various 3 1/4 - 3 1/2"  air cleaners and the one that was marked 4"  actually wouldnt fit as it 

was actually 4 9/16"      So he hunt was on, and  I found 3 vintage Edmunds air cleaners which after some searching

found that the 4" air cleaner cartridges for a VW fit perfectly.      On they went

Almost immediately I was asked where  I had gotten them and could they get a set.  Of course finding the original  Edmunds was next

to impossible. Over the next year I lent my intakes to someone who then copied them and  they are in fact available today.

 

 

Here is the  Eddy  Edmunds  1952  - "Edmunds Racing" triple carb intake for the 25 1/2"  motor.

Where we put the triple of our dragster,  we didn't have the firewall restrictions so we were able to move up to 6" air cleaners.

when your do the calculations there is a huge difference between a 4" and 6" air cleaner and  we could see on the dyno, but

of course I had access to  air filter engineering test equipment and it was  unbelievable the difference between the 2, never mind 

when we tested some of the so called 4" air cleaners which were really 3 1/4" and 3 1/2" air cleaners.

Here is a closer look at that air cleaner which is actually 6 1/2" air cleaner.

Here is the factory dual carb intake I referenced and then the modified version to get it under the hood of a car.

This being the factory air cleaner for the dual carb setup but they maybe the rarest of the rare for mopar air cleaners

This being a reproduction of a 1930s Mopar aair cleaner which was later used by the 1951 GMC  pickups

and  in the late 1940s and early 1950 Fords,   We had the star tops made and chromed or powder coated.

This allowed to use a modern air cleaner element.

Here is one of the original 1930s air cleaner.

Of course the air cleaner as much as I would love to have it on my 1949 Plymouth, or my buddy George Asche Jr would love 

to have it on his prized 1929 Desoto, they just wont work without a major firewall modification.  George as you will see

here has run the Edmunds Racing intake since 1954 and it was instrumental to his going undefeated in 1954

on Daytona Beech on the famed flying mile drag race course.    Hitting 142 mph over the course George stunned

those running everything from the hot v8s of the day, Hemi's, a hot rod Lincoln dragster to a v12 Jaguar.  Of course

George knew if you remove the air cleaners, as much as that put the engine at great risk, the increase in performance was obvious.

Over the years I  have often toyed with the idea of offsetting the larger 6" or 6 1/2" air cleaners to get the major increase in  air surface and in some cases 

even with  dual carb intakes the offset is needed to avoid conflicts under the hood.  A few years ago a customer we were doing an engine for, took

a sketch I made,  our stop air cleaner creations and created 6 offset air cleaners. Here are those prototypes

Which if you look closely you will notice they will sit nicely on the flare top carter ball and ball carbs.

Which allow you to use the factory air cleaner clamps for a super snug fit

Here is the prototype sitting on my 1949 Plymouth

20180318_170357.jpg.03c3600c06c1c4302a9f81664fa56700.jpg

 

This is just a mock up but you will notice the 6 1/2" air cleaner fit perfectly and is no closer

to the firewall that the original Edmunds Air Cleaners.

Now the creator of the  original prototype  found out just how big of an undertaking the offset base was to make and 

really had no interest in making any more and believe me I tried.  In fact I chose not to mention him here, not

in an effort to avoid giving him credit, but because naming him could wind up unleashing the masses trying to 

pester him to make "just one more set" for them.

 

At this point  I could  just leave it be,   have the 3 air cleaners finished and  given to George Asche Jr for his 90th birthday and the other 3 finished up

and place on our 1936 Fargo which although rock stock internally, sports an AoK triple and a set of George's  headers made from factory exhaust manifolds

like my 1949 Plymouth.      BUT... and it is a Big but,  that really isnt the AoK style to  make something that no one can ever have.

 

To that (and congratulations if you have read through this book to this point.... lol) another AoK customer and  Flathead Mopar super fan has 

decided to join forces and see if he can get the offset air cleaner bottoms made.    In this case, he is well versed with the manufacturing world

both in the United States,  Canada,  off shore in the orient and  down under in Australia.

 

i know  there is massive amount of interest, but  and again its a big but, at what price is that interest ?

I know if they were $10 we could sell, oh about a million of them,  and if they were  $1500  for one we would sell  pretty close to 0.   I say pretty close

because I know a couple of guys who have already offered me a ridiculous amount of money to scoop 3 of the ones I  just had powder coated.

 

I also know how pricy it is to create the star tops and those air cleaners without the offset are in the $150 range.    It is possible that the offset

bottoms could be sold just as a bottom where a customer could do their own air cleaner element and top or as a complete air cleaner.   I can tell you

if we can make these  cheap, as in low cost and high quality we will, but at the end of the day demand will determine if the project gets off the ground.

 

If your interested,  drop me a PM here or a note to me at fargopickupking@yahoo.com.  Of course is your interested at the $$  below what the current off shore bottoms

with hose clamp connection, replaceable elements & star top air cleaners, sorry but at this point I don't think there is a need to get in touch with  us, because unless

something unforeseen happens I don't see  that  happening.

 

Thanks -

 

AoK boys

Sadly I've sold my 50 Plymouth and wagon but this offset air cleaner would have been a huge find when I had my Plymouth.  

 

If you can get the air cleaner with the offset bottom , very cool 30s star top (huge key) and an element for $200 or under I think you have hit a home run.  

 

Just the banged up old ones with out an offset I've seen them sell for north of that and nice ones running up over $500 although how many are sold at that price is a good question .

 

Potentially a value added people could get them powder coated to match their car so if you sold them black  and/or chrome bit also had them so they were ready powder coat or be painted that's a great option.

Im sorry to hear that Paul, but believe me I completely understand.  On the air cleaner,   that is a reasonable target.   The challenge is most  air filters are made off shore where you need to over thousands to make  the project viable.      This project just is not going to be of a scale that your going out to place the minimum order quantities  in the thousands, which means a much smaller run and cost for tooling and dies for the run that has to be spread over the run.

I know what the star tops costed, which was a buddy that owns a manufacturing company who when asked if he could make them, he said let me get back to you.  Next thing he showed up with tops and had invested a stupid amount in tooling to produce them. Of course he wanted a set and one of our AoK triples so that was his motivation, more than trying to make it a profitable or even a break even project.

 

For the offset bases that direction wont work so the search is on for a few different options to make something of a decent quality which we can add a commercially available air filter element and a star top.   The  idea of having them so that they are ready to paint or powder coat is likely a good suggestion  as you are right a lot of people might like them the same color as their car.
