Damn that sounds like a badass car you've got there. I can be of no help on your cam question, but I can try to direct you in the right place.
Ed Curtis of Flowtech Induction grinds custom camshafts specifically for your combination. You tell him what you have, and what you want out of it, and he will work the magic for you.
I'd suggest checking out what he can do for you. Heres a link to his site-
