Boiling over

My new rebuilt 302 keeps boiling over everytime the thermostat opens for the first time on warmup. If I have the cap on, it purges in the overflow, but if the cap is off, it spits out 2 feet in the air! It is fine once it starts flowing and runs fine. I originally thought it was air in the block or the wrong water pump, but now am not sure. Any ideas on what could cause this?

If the radiator isn't partially plugged, you may need a new pressure cap. You say it runs fine once it starts flowing, so I'd try a new cap. ...Terry
