454 performance tweak

I've never worked with a 454 before, and I'm thinking of getting a "basic" rebuildable from a local yard. I assume a garden variety 454 will put out about 300hp, and I'd like to target a mild upgrade to approx 400bhp. I hate to do it "barnyard style" (which is what I usually do) by just throwing a cam in it, boring it out, putting on an aftermarket manifold and a set of headers. Where do I go to get intelligent configuration information that would help me make smart choices to get to 400 hp??? Is there an on-line program that I can find that will let me plug in what I'm starting with and will feed me back decent options?? Anybody? Buehler?
