I can't help you with a Holley, but I can tell you that my Edelbrock will be empty in 10 to 11 days pretty consistently. I have a Schrader valve just under the fuel filler neck that I use to put 1-2 psi air pressure to the fuel tank for a minute or so to fill the carb when I haven't driven for a while.
