There's no replacement for displacement. Or something like that.... what is your purpose for the car? You're looking for the ultimate, but that could be a lot of different things... ultimate tire smoker, top speed king, 1/4 mile monster, reliable daily driver. Once you know what you want the car to do it should be easy to figure out how to get there.
With a street / strip car you will always be compromising some amount of each. Be honest with yourself about what that ratio should be, and your choices for cam/intake/carb/etc will be a lot easier.
