I would suggest this cam.
Comp Cams Magnum, part number 34-336-4, grind number 292H. It's a hydraulic flat tappet and is intended for street strip use. It's .560 lift, 292 duration, 244 duration at .050 lift, a 110 degree LCA and a powerband of 2500-6500. It would need at least a 3000+ stall speed converter like you have, and has a rough idle.
I'd suggest either an Edelbrock RPM Air Gap for street use or a Victor JR for more strip use. Then I'd say probably an 850 considering how aggressive the setup will be.
