The Weber is a solution to a nonexistent problem, it's very expensive and requires a lot of adapting. Just pick out the year and displacement of the engine you're working on and find the corresponding Carter number in Jon's list. It will bolt on without any fuss or adapting, and it will be far better than either a Rochester or a Weber.
