I'm not saying you can't run a progressive set up on a tunnel ram but I think the design will make the front two cylinders way lean. Now you could jet up the primary side on the rear carb but I think 1 to 1 works best on a tunnel ram. That Chevy 409 had a carb base gasket leak and the front 2 were so lean the engine was skipping. And you can certainly fab up some linkage no matter which way you go. Good luck.

With a carb base leak you're going to have lean problems no matter what.. that's not even any kind of an ideal situation....
When I had progressive I had absolutely no issues with the front cylinders when I ran the rear carb primarily...
It sounds good in theory but what it is is a perpetually spoken mith because it seems to make sense but in reality it's not true...
