1992 Chevy Lumina Front Wheel Drive Automatic 100600 miles

I've replaced radiator, water pump, thermostat and heater core. There are no visible leaks in the system when car is running. Upon acceleration the reservoir fills up and discharges out of the overflow. The car runs smooth with no vapor comming from the exaust.
Do you
