360 Rebuild Recommendations

I work with a computer for a living. Very minimum knowledge of engine mechanics. I would like to say, if I had my way, this would be a 10s car build. But we are building my sons 1st car. So we have a stock 360 to put in the Dart. The HP will be probably what I'm looking for my son, 15-16sec car.

Here is the trick. Can we cam swap to something that sounds mean without majorly adding HP. He has also mentioned the blown look. Maybe a high rise intake with scoop sticking out hood? Still keeping performance to a mild daily driver?

Cam suggestion?
Rebuild kit?
Intake?

Name and where to buy would be great?
