running a #94 on my banger

[Mike/Nebraska]

Well I finally got an intake so I'm going to put my #94 on with a header, I know some of you run downdrafts on your bangers so I was woondering how much pressure do I need in an electric fuel pump? And...where would I buy such a thing, Also where should I start on jets. My motor hasa counterbalanced crank, a B cam, a Snyders 5.5 head and a lightened flywheel. I also have an over drive.
