You should get some more feed back on what cam but you can start doing some reading here to start.

I am no expert but compression ratio and how much boost you plan on running will help with determining what cam. Exhaust you are running also.
Are you looking for a flat tappet or roller and hydraulic or solid lifter. HP you are looking for and cost will determine which you need.
