Installed manifold and new carb this week.
 
I used 3/16" spacers under the 55 bell crank.  These were needed to clear the "B" manifold



 I fabricated a link (copied from Joe Johnson)  to eliminate the spring linkage, I now can confirm the spring linkage is needed to engage the kick down.




Because the Edelbrck is a wider carb I had to build out the rear fastener to use the Spring

For now I am using a Ford look alive 2" drop base air cleaner with a 1/4" spacer.  I have about an inch of extra clearance, I might use a 1/2" spacer OR maybe I will source a 57 air cleaner..................
Right now I am in the process of dialing in the carb.  Ni I am not driving around with Play Dough under the hood LOL

Very nice work looks great. IMO, that aircleaner assembly looks natural....

Talking with someone that knows the 55,56, 57 Tbirds...................the 57 uses a solid link, because the "spring action" is built into the bell crank.  So it (57 bell crank) uses the same"concept" but it's not really obvious.   When I used the solid link with the 55 bell crank there was not enough movement/leverage to engage the trans kick down.  That additional spring action keeps pushing the linkage when the carb is fully opened.  I can only guess they designed it this way to allow for wide open throttle without the downshift, giving you the option to stop applying pressure unless you need the acceleration/down shift. 

After learning this I had to remove and "retire" the solid link that took me hours to fabricate...............  When I installed the spring/link with the 55 bell crank my trans is now down shifting as expected

Air cleaner was $70 on ebay with a washable filter element.   I didn't want to cut up a $500 repro 57 air cleaner that might not fit under the hood even if modded

I really appreciate your coming back to explain that. I had no idea.
