25 or less, Doug. I had a Holley black pump and it would not have enough volume, to keep a quadrajet full, especially at launch. I switched to a Magnafuel 275 and reg., and it made a big difference. Dont use a small fuel pressure guage, a full sized one will be more honest. Run at least a -8 or even a -10 line.
