Can a 400BBM w/cheap aluminum heads compete/dominate against the street LS?

Step one, if i was trying that , would be getting the best heads you can afford. Step two would be stroking it to 470, or 512 inches. Step three would be a big nitrous setup.
I have a friend who has a stroked 408 LS with a single turbo, in a street driven 78 malibu. It makes 1200 at the crank. Pretty high bar to get over.
