I have a 3 deuce setup on my '56 312. At the present, only the center carb (a 94) is active with the outside carbs blocked off. It's an Offenhauser manifold. I purchased a set of 2110's with the intent to mount them using a progressive linkage. To make a long story short, I have decided to go to a single 4-bbl. using either a 9425-B or a Blue Thunder for street use and easier maintenance. I haven't heard back from Mummerts about a new BT but if anyone out there has one or even a B they want to work a swap on, I'm open. I also have the ribbed Offenhauser valve covers that I would like to swap out for the TBird covers. Anyone interested?
