My Thunderbird is a "wife" compromise as well.  My wife wanted a convertible.  I wanted a 50s Y-Block hot rod.  Works for both of us.

Sold the Sedan when I bought Convertible. Wife wants to park in Garage in Winter. Not sure Why???

  

Love your car's..

To check vacuum Leaks use an unlit Propane Torch or what we up North call "Quick Start". Basically Ether in a Spray can.If U notice an increase in RPM  thats usually a Leak sucking in Air.

  

I know the problem is with the End carbs. But, Charlie reworked both of them at the throttle plates, are tightly closed. So there is nothing wrong with the center carburetor. So trying to figure out if it's vacuum leak or what.

The issue I had with my triple Holley 94s was with the center carb.  It had an off idle stumble.  We could never find the exact problem, so Charlie replaced the carb for me and it worked perfectly after that. If your engine runs OK with the end carbs blocked off, your problem is in one or both of the end carbs. These carburetors are 60 years old. I suspect the circuits are blocked. Try to find which one is causing the problem and swap it out. Charlie has a mountain of them in his back yard.

"Trips"  short for "Triples" maybe? As in 3 Carburetors.

  

Yep 3-2's..

Trips..

49Bomb. . . .  If the center carb works perfect all alone send Charlie back his 2 outer ones and get 2 more centers putting each one one in the center alone and see if everything runs right. Then add them to the outer mounts one at a time. I have no idea why everyone thinks you need non idle outers.

In the 60's when I started with 3 94's or 97's they were ALL the same. We idled on all of them and when we set the progressive linkage the outers squirted in fuel with no stumble. We set the outer floats a little lower so vibration would not cause flooding at idle, back then we were on them a lot more so it wwas not a problem too much. Were not talking a 348 Scrubby here with the correct Rochesters. I had a GMC 270  6 with a Howard log manifold with 5 carbs and idled on all 5.

I have dual quads and idle on both, it's a must. I only choke the rear one, but for starting but need to squirt both when the engine is stone cold. 

You can put a plate under the center with a hose fitting for your PCV and drill and tap the manifold anywhere for the Power Brakes I'd do it behind the rear carb or get a second plate. 1/2" aluminum are ez to find I think Speedway sell them and you can drill and tap them or drill a 3/8" hole and press in a steel piece of line with JB weld on it.

This is hotrodding and it ain't ever ez or cheap... You should price out 2 matched Carter small base WCFB's and and Edelbrock restored dual quads set up..Then you make the linkage...Good luck and don't give up...I have no idea what trips are...but I know 3-2's when I see them.
