Dp vs. vacuum carbs

Whatīs the difference between a double pumper carb and an ordinary vacuum controlled carb? Dpīs are supposed to be better suited to light street vehicles, or so Iīve read, but to me it sounds like itīs more up to the gear ratio (if the engine can turn the wheels without much hassle, so to speak).
Mpg aside, which one is the better performer? Reason Iīm asking is because I can get a Holley 800 dp for a very good price......and if it just sucks gas with no gain in performance I donīt want it![img]/wwwthreads_images/icons/smile.gif[/img]


If a Blazer runs smooth, it isnīt really a Blazer[img]/wwwthreads_images/icons/crazy.gif[/img]
