I am going to try to crash right now, so I will give a more lengthly answer tomorrow sometime mid-day.
But the way I look at it, your car can't be a sleeper. I know what you mean though, you are looking for the stock look to surprise people.

Most higher power mods show themselves either when running or because they are visable.

There are cams out there now that are made to make power but be tame sounding. Good set of heads is easy to cover up.
Another thing....low 12's is still faster than damn near anything you will run up against.
