Full Throtle = Loss of power

When i give my car half throtle it has a ton of power but when i floor it it begins to gain power then it just drops off would this mean my Vacume Secondaries need to get more fuel? Im new to carbs so any help would be great. The carb is a Speed Demon 750 cfm.

You can have the problem you're having from being too rich, or too lean. Looking at the plugs should let you know which you are. From there you can determine what tuning is needed.
