Your right Greg, it allows the 1 bbl carbs to bolt to the 2 bbl bolt pattern. Its really several intakes in one where you can run it as a 3 x 1 intake or a 3 x 2 setup by removing the 1 bbl adapters. Or you could even make it a 2 x 1 or a 2 x 2 configuration by blocking off the center position as well.
