Hello, i have a manual shift 57 E code bird that is missing the bell crank that mounts on the rear of the intake manifold to join the carbs with the gas pedal linkage (looks like a elaborate mouse trap) my question is this a standard part and can i use the regular 57 bird part or is it a 'special pay thruogh the nose part' Either way if someone has one for sale and doesn't mind dealing with a Aussie i would be gratfull, regards tony b

Hi Tony,
Welcome to the Forum.
The part that you're looking for, is 'special' to the 'Bird.
I am forwarding your parts inquiry to someone who I think can help you out. He is not on our Forum.
Regards,

No Shortcuts,
Thanks for doing that if he has one it will be one less thing to tick off the list.

Hi Tony,
The throttle linkage for the 'E' code '57 'Bird between the firewall bell crank and the bell crank located between the carburetors is different depending on the transmission used.
The linkage for the automatic looks the most like a mousetrap because of the additional bell crank mounted on the intake manifold near the firewall. The linkage for the T-85 3 speed and the T-85 3 speed with overdrive is significantly simpler because there is no bell crank mounted on the intake manifold by the firewall.
For the 'E' 'Bird, the bell crank mounted on the firewall is unique. It is different from either the firewall bell crank used for 'D' code automatic transmission and that is also different from the firewall bell crank used for 'D' code 3 speed or 3 speed with overdrive transmissions.
A good source for pictures of these linkage set-ups is pages 344, 345, 346, and 347 of the 1949-1959 Ford Car Parts and Accessories Illustration Catalog.
IF the only part you're lacking is the rod between the firewall bell crank and the intake manifold center bell crank (part no. 9747), you are in great shape. The 3 speed connecting piece is simpler than the 3 speed overdrive piece which has a spring mechanism incorporated in it.
I'll email you tomorrow through your Forum account after I've heard back on my inquiry. 
Regards,

noshortcuts,
Thanks for the info as my bird is a 3speed overdrive unit, what you are saying is that the bell crank is deleted?
All the resource books i have looked at for e codes have all shown the bell crank mounted on the intake manifold, in fact i have seen 3 different styles so when i took a look at mine and there isn't any such device i thought it has been messed around with!!
I will endeavor to take a photo of the linkage (it does have the rod with the built in spring that you mention) and post it here, perhaps its me but it just dont look like Ford would have built it that way.
Your advise is very much appreciated,
regards tony b

Correct, Tony. The mousetrap looking bell crank used on the driver's side rear corner of the intake manifold, nearest the battery and the firewall, is present only on '57 'Birds with the automatic transmission.
That bell crank is employed with the auto trans to actuate a kickdown rod to the transmission which forces the trans to downshift.
IF you wish, use the Forum email system and send me your snail mail address. I'll be glad to send you photocopies of the linkage pictures for the 'E' 'Bird with the three different throttle linkage configurations... auto. trans, T-85 three speed, T-85 three speed w/ overdrive. These pictures would be from the Ford parts book I previously mentioned.
IF you've got the overdrive transmission, the connection between the firewall bell crank and the bell crank located between the two carburetors on the 'Bird (because the carbs are mounted backwards, i.e. choke plates facing the rear of the car) is a straight rod with an encased spring in the middle of it. The length of the rod can be adjusted as there is a threaded section adjacent to the enclosed spring and a nut that can lock the length adjustment.
Wish I could upload a picture for you...
Hope this helps.
Regards,

I managed to load a photo of the linkage on the bird but deleted the text?
Your advise or others is most welcome.

The firewall linkage appears to be correct.I would have to check the angle to make sure,but I think its right.
The linkage rod from the firewall to the carb bellcrank is correct for an overdrive equipted car.
The center carb bellcrank is incorrect.Appears to be some sort of home brew device.
Also incorrect is the short manifold hold down clamp.It should be the longer length like the front one is.
Rear carb is incorrect for an "E" code engine.
Would like to see a picture of the rest of the carbs linkage from the passengers side as well as a pic of the front carb.

The 49-59 Ford Car Parts manual is a treasure trove. Highly recommended. Here are the pages related to E-code Thunderbirds for 57.
Hmm, they were scaled down quite a bit when uploaded. Hope you can make out the details you need.

Hi Tony,
Oldmics has a good eye!
- The rear carb is not the Holley 4000 Ford used in 1957 for the 'E' code set-ups. The presence of the spark control valve is the 'tell' on that. With the choke housing attached to the carburetor body, I'd expect it to be 1956 vintage.
Unless the rear carburetor has been modified there are two immediate concerns.
First, assuming that it was originally purposed as a '56 single quad application carburetor, it has no balance tube to allow connecting it to the front carburetor to equalize the vacuum signal to assure that the secondaries on both carburetors open simultaneously.
Second, the rear carburetor is the source for the vacuum signal provided to the distributor vacuum advance chamber. The '56 Holley 4000 distributor vacuum signal source for the distributor is not correct for the '57 distributor. The Holley 4000s used on the '57 'E' code cars had a different distributor vacuum take-off point and the elimination of the spark control valve on the '57 'E' code carburetors verifies that.
There are other 'changes' that should be made if you want the best performance from this carb IF it is partnered with a '57 'E' code carb on the intake manifold OR IF it is partnered with another '56 vintage Holley 4000.
____________
-After the end of the '57 model year, Ford continued to supply parts for the dual quad set-up. Example, there were valley pans produced to sell over the Ford parts counter to work with the '57 'E' code intake manifold. The later produced valley pans 'worked', but were slightly different because the other valley pans being made for y-blocks at that time had a dome at the base of the oil fill tube. So, the later 'E' code replacement valley pans had the dome, too. To the point, I've been told by someone more knowledgeable than me that the center bell crank on your engine is likely a later version. Made by or for Ford, but 'slightly different'.
Again, told to me, the throttle linkage rod between the firewall bell crank and the bell crank between the two carburetors is probably adjusted the way it is, i.e. it appears to be extended excessively where it connects to the firewall bell crank, because of an inaccuracy in the making of the later replacement center bell crank. The suggestion is that the two bell cranks on your engine do not align per 1957 original equipment pieces. Your firewall bell crank appears to be correct, OR it's a faithful reproduction.
Does your 'Bird have an 'E' data plate or was your vehicle retrofitted with the dual quad set-up?
____________
One addition to what Oldmics mentioned about the intake manifold clamps. The rubber hose going to the vacuum advance unit on the tach drive distributor is a retrofit. The factory installation used a steel tube between the rear carburetor and the distributor. If you're 'efforting' to make it look 'original', reproductions are available.
____________
Oldmics request for additional pictures of the entire set-up would be helpful in advising you further. -Especially in light of one carburetor definitely not being original.
Hope this helps.

Thank you to everbody who has responded, the more i look at the car the more it apears to have a cut price restoration and as i am not one to cut corners i geuss its up to me to put it right so your advise and diagrams have been invaluable. I have owned many Y Block vehicles but never an E code or a manual with overdrive so this is a learning experience. I will take more pics of the carbs and load them early next week, once again thanks for your help, regards tony b

To Tony... I've been told by someone more knowledgeable than me that the center bell crank on your engine is likely a later version. Made by or for Ford, but 'slightly different'.
Again, told to me, the throttle linkage rod between the firewall bell crank and the bell crank between the two carburetors is probably adjusted the way it is, i.e. it appears to be extended excessively where it connects to the firewall bell crank, because of an inaccuracy in the making of the later replacement center bell crank. The suggestion is that the two bell cranks on your engine do not align per 1957 original equipment pieces. Your firewall bell crank appears to be correct, OR it's a faithful reproduction.
Well, sometimes we have second thought on things.  My more knowledgeable friend called me this morning to rehash the center bell crank issue. He KNOWS he's seen it used on a y-block 'E' set-up before, KNOWS that the two bell cranks do not align properly, KNOWS that it is a Ford supplied part, BUT vaguely recalls that someone may have indicated that it was a re-purposed component from a '60s Ford 390, 406, or 427 FE multiple carburetion set-up.
I'm glad that I'm not the only one having trouble remembering things lately! Maybe someone who knows the FE stuff can help on whether Tony's center bell crank is indeed a borrowed Ford FE component?

Heres the 427 dual quad setup - look familiar ???

Theres still something a little wierd about how that center bellcrank is attached to the manifold.
