Well the 4150 fells under the 4100 series of Holley carbs.
There's two major versions of the 4150 design dealing with secondary opening; the vacuum secondary(street) & double pumper(track).
So basically the DP is a mechanical secondary Holley Carb ( any Holley Carb
) that has a 'second' accelerator 'pump' for the rear.
