I agree with those who say that you should always run straight linkage with dual carbs. If you insist on running progressive, there are a couple of ways to minimize the problems. The first is The Edelbrock "SlingShot" as shown above, as it has a fuel distribution pattern similar to a four barrel carburetor. The second is to run what I call a "biased" manifold where the front carb is mounted in just about the same position as the carburetor on a stock manifold. and is used as the primary. That way, you will at least have normal fuel distribution most of the time. Only when you kick in the secondary (rear) carb will the fuel distribution get funky. Also, the generator relocation problem goes away. Here's what I'm talking about :
