Hi Tom,



I've done a comparison of two original '57 Ford dual quad air cleaner housings for the 'Bird and the passenger car. I'm understanding that there are numerous reproductions out there...



The housing bases are identical. The passenger car bottom base was simply rotated 180 degrees for use on the 'Bird.



The upper housings are 'related' to each other. The total height of the two upper housings are identical. However, the height dimension of the domes differ by one inch. Because the top section of the air cleaner housing was also rotated 180 degrees for use on the 'Bird, the stamping 'FRONT' on the top of the one dome was also rotated 180 degrees and is relocated to the position of the opposite dome from the passenger car unit.



Again, the total height of the passenger car and 'Bird air cleaner upper housings are the same. Because the domes on the 'Bird upper housing are one inch taller than the domes on the passenger car unit, the height of the side 'skirt' of the passenger car air cleaner housing is one inch taller than the 'skirt' on the 'Bird housing.



Related to the difference in the height of the side 'skirt' of the two upper housings, the original passenger car air cleaner element was taller than the 'Bird element.



Hope this helps!

No short cuts, I understand the difference between the Bird and car E aircleaners, My thought was would there be any power difference, when they were both used on the same engine. Thanks Tom

I'd be interested in how a '57 'E' 'Bird air cleaner housing performed with a '57 'E' code passenger car filter element compared to any of the other air cleaner assemblies that Ford offered. It would seem that there would be less restriction to air flow to the carburetors...



Unfortunately the application information would not work on the little 'Birds because of hood clearance.

And it may run worse due to the fact that more air flow could lean out the mixture.

Now if it was jetted up and had more air flow.

Ted has lots of toys and options to play with - thats for sure.

By the way-good call on the Bird and passenger air filter comparisons

TED, all of us y block effected, inflicted, fans sit by for your results, like an expectant father in the waiting room. I havent heard or seen there was an OFFY 2x4 and was eager to see pic  of one if anyone here has one. I do have local CAIN 2 x4 intake if interested but as not a regular item may be not be relevant in your test programme. It is open plane and suit high rpm use more than cruising i would think.

Ted, these are 2 Cain intakes, basically the same except for minor casting changes, thought you guys might be interested to see unusual ones from over here.

yyy

Called Ted's shop today.  Wouldn't come to the phone, he was busy with the dyno.  Wonder what he found?
