This is my daily driver in the summer so I'd like to have something that will pull smooth down low (about 1800 cruising rpm) and still give me a lot of power at the strip. When racing rpms' are between 3-5800rpm generally. Some things I'm wondering are: Will I need a small base circle cam? Should I select a "nitrous" cam profile?

I've been running an XE270HR in the current 350 and it feels perfect, with the added cubes and better cylinder heads should I be looking at a 284hr or similar?
