Where do you want the power. Right now you have a cam that's meant for high rpm hp and a intake thats meant for low and mid range torque. Chances are there is no shelf cams that are going to work properly with your combination, EPS has a cam that is meant for a motor with a single plain but I don't think there are any for a carb'd dual plane. Your best bet would be to call or email some of the vendors on here and get a custom cam from one of them. My list of people to contact would be Brian Tooley at BTR, Martin@ Tick Performance, Geoff at EPS, and Kip@ Cam Motion.
Also in order to get anything that resembles an intelligent answer your going to need to give more details, weight of the car, what transmission, what torque converter, rear gear ratio, and any other modifications the car has.
