I'm using twin 40 Dellorto's, a Holley Red pump and external Holley low pressure regulator set at about 2.5 psi. For a while I ran it between 3 - 4 psi, it ran pretty decent. But when I backed the fuel pressure off to 2.5, I noticed an increase in power, so I think 2.5 is a good pressure for Weber/Delloroto's...of course it depends on your jetting too. You can cheat rich jets by backing the fuel pressure off a little more, or run a little more pressure if you're running lean.
