Lets start with a couple simple questions as you are being way to vague.

How high are you willing to spin your motor?
How big of a converter are you willing to go with?
How steep of gears can you tolerate?

You say you want the biggest cam for max hp/tq but the bigger you go generally move peak tq higher up the rpm band to create more hp (hp=tq*rpm/5252). So the above 3 questions weigh in.
