Question about carbs for tunnel rams

I just remembered I use the mr. Gasket dual quad linkage. I think it's like $38 now but I remember 32 and bitching LOL... I'm sure you can get it at any parts store I know I did if not they can order it for Mr Gasket...
You see how I have it hooked up and I'm also pointing out on the front carburetor a lower hole closer to the fulcrum point that I use when I want to set up progressive. I'm sure there's a little ear on that carburetor linkage that I had to cut off in that area as well. And I may have had to drill that hole a little bigger. Also I utilize the double slider when I do the progressive that's provided in the kit. Hooking it up Progressive has quite a few advantages. Give it more drivability without losing ET. it does feel a little Turbo-ish when the second carburetor kicks in and you can feel it when the spring gets tighter. I like the extra pump squirt of both at once sometimes 1to1...
