A couple questions about supercharging a 440

The less i have to dig into it the better, I'll only be spending more money the further i go, be it by necessity or by my sheer desire to buy new things. If i can achieve 600-ish hp safely with the rotating assembly and cam that are in it then i will leave it alone. The engine was rebuilt just before i got the car, I'll have to dig through the receipts to see who did it but everything is stock spec except what i mentioned before. If the cast pistons can handle the blower at a modest boost level without detonation then i guess I'm just over thinking it.
