360 Build for my wife Questions

If the car has power brakes I would keep the cam with the one you have..You dont want an open plenium intake either they are not a good around town intake they are more for mid range and up....As far as sound if its got headers or not with dual exhaust and flowmaster 44s it will sound good..If you want it loud then use the 40 series but it might have droaning issues...Bill
