Does anyone have a Ford round element they can measure the height of?  See my 8-1 post on an E Code Air Cleaner Element source.  I found out that it is $10.00 less without the AC part number on it, which isn't important for Ford applications.

Medium rare-please.

Oldmics has helped me with numerous pieces of dual quad info in the past. I do not have a 'Bird and a passenger car dual quad air cleaner housing here to measure, but the domes on the 'Bird air cleaner housing definitely rise higher from the top housing surface than the domes on the passenger car unit. That's one of the ways to tell the applications apart!

No way will a passenger car air filter fit under a T Bird hood

Or are we discussing air filter ELEMENTS ???????????????????

inside the filters.

Oldmics

I can get things started with a round T Bird style filter. I am out of passenger filters at the moment.

These are measurement taken on the top section only.None of these measurements will include the bottom section.

 The heigth of the air filter element installed into the bottom section can and will determine the ultimte heigth of the entire assembly.

18 3/8 O.D.-measured at the bottom of the outermost flange

Heigth is a bit tougher to measure since there are several "steps" of the filter top.

Bottom to first step- 1.750

Bottom to second step - 2.00

Bottom to 3rd step - 2.400

Bottom to 4th step - 2.5

 Dome heigth measured on the outside -highest point downwards to the 3rd step - 1.950- subtract .100 for measurement to 4th step on top of filter. Due to placement and pitch of each dome,this is a variable figure depending upon where the measurement is taken.

4.575 total heigth from bottom to top of front dome

4.475 total heigth from bottom to top of rear dome

Dome heigth measured inside of air cleaner -  2.100

Rear dome is positioned with a slight tilt towards the rear-never noticed this before

The domes are the same heigth on both the passenger car aircleaner and a T Bird .

The T Bird dome appears to be higher BUT that is because the filter can is LOWERED and thinner.

This creates the illusion of a taller dome.Thus the T Bird requires a thinner (not as tall) air filter element.

Hope this helps,Oldmics

Thanks for this information...It apperas I have a Passenger car Cleaner on a TBird...

Any one like to trade??

Thanks

Welcome to the site, Dale. I'm sure many on this site would like to help you with the info. you seek. However, many, like myself, do not have one of each unit to reference. A '57 Ford passenger car dual quad air cleaner element went for $504 within the last week on eBay and it was NOT N.O.S.!



IF you are unable to get a response to your inquiry, I've got a friend who has both. I expect to visit him sometime in the next two weeks. He's several hours away from me... The number of dimensional differences are more than most would expect in my opinion. Email me if you want me to pursue this for you...

Could anyone tell me the dimensional differences between an E-Code TBird and Passenger Car Air Cleaner.

Thanks

As to the reason that so many of the E setups were removed back in the day because of drivability and maintenance problems, I have my own theory as to one of the problems. When I first put the E set up on my '57 in '65, I did not have the E carbs and rebuilt '56 Ford single 4 barrel carbs and jetted them per the spec's in the 1962 Hot Rod Magazine Ford Performance Manual. It ran great. In later years I came up with two different original E carb sets. Both sets had the jetting for the '56 single 4 barrel which was way too rich for the dual quad setup. I used the jets from my old carbs and it works fine. Primary's are the same as standard Holly jets and no problem to fine. The secondary tubes are tough to find. In '65 I took apart every Teapot Holley I could find and eventualy found 4 of the correct jets. Wish I could find some assorted sizes today!

Yes, the '57 Ford passenger car dual quad air cleaner housing and the Thunderbird dual quad air cleaner housing are significantly different. The carbs on the 'Bird were mounted backwards on the intake manifold when compared to the '57 passenger car dual quad or the '55 or '56 Ford/Mercury passenger car and 'Bird single quad Holley 4000 teapot applications. The mounting of the carbs backwards on the dual quad '57 'Birds was to provide needed hood clearance. The sheet metal air cleaner housings were significantly different in several ways. The 'domes' on the top of the 'Bird housing are higher than on the passenger car and positioned differently front to back. The air cleaner bases are different as well because the carb. openings are positioned differently on the piece front to back. Also, the two applications, from the factory, had two different height air filter elements because the housing height is different. -The passenger car takes the taller filter element. Again, we're just talking air cleaner housings, but there are other differences between the dual quad passenger car and 'Bird applications to include carb. to intake manifold spacers, throttle linkage, and fuel lines.



Hope this helps!
