Big horsepower 318 builds

I wish I had a unlimited checkbook. Oops, I'm not going to talk about my 273. We need to concentrate on 318's. Let's start with a stock or .030 over bore, and a stock stroke crank. What pistons, cam, and heads will we need for good horsepower? Of course it will have a good intake/carb combo and headers. Barely streetable or street/strip if you will. There are a lot of guys that drive 5-600 horses on the street. WTF, it's so easy to overbuild.

If you look at the LS 4.8l and 5.3l 500 hp combos probably would do similar to a 273 318 would have similar out comes.
