440 Camshaft recommendations for up to 6-6,500 rpm?

I'm not a big block specialist but a couple questions come to mind first off, what is your rear end ratio, #2 automatic or 4-speed,#3 carburation and manifold setup #4 will it be Street driven and what type of Cam flat tap it roller?
3.23 rear diff, auto 727, edelbrock AVS2 800 cfm, edelbrock performer RPM, flat tappet.
