TT406 that is a trick looking carb you have there, never seen anything like it. I'm sure it would help but I think a 2-4 set up may be better in my case. How much are you selling them for? I could toy with the idea of angling the runners toward the center of the plenum where that " extended Venturi" carb you have could be situated over the runners.
Everyone, just realize that this is a pump gas (93 octane)street car that will go to the track about 3-4 times a year maybe more if time allows. If the horsepower is down 3-4% it still may make enough. Looking for at least a 9.80 in the 1/4. I go to the local tracks to run my car and pass out flyers to advertise my chassis dyno. The old combo could drive to the 1/8 mi. track and run high 6's. Now I'm looking for low 6's.I do dyno tuning on carburated cars for a hobbie and a little cash. My real job is metalwork, you can see the press brake and shear in the background.
