It will definitely overheat without a thermostat. It takes a while to get all the coolant up to temp, but once it does it won't stay in the rad long enough to cool off any. Also make sure the fans are working. Are you running water in the cooling system or 50-50 mix of coolant and water? Plain water has a much lower boiling point than antifreeze and will help it to overheat too. Good luck.

Do what Scooter said, and put a new cap on the rad. if you havn't already. The pressure in the rad. and the antifreeze is what helps keep the temp. down. Running no thermostat is an old wifes tale and does not work. If the coolant isn't in he rad. long enough how is it going to be cooled down?

Check your hoses and make sure your water is circulating.
Remember it's reversed cooled.
I had a problem once where the waterpump blade actually spun on the shaft. This was a reconditioned waterpump that I bought from Napa. If that's not the case make sure your fans are properly coming on. Bleed the system as well.

Mine did that when I replaced the water pump because I didn't fill up the water pump with coolant before putting the thermostat in it. The waterpump blades were just spinning in the air and not producing any suction to pull the water out of the radiator and into the motor, so be sure its primed correctly.
I'm assuming it wasn't circulating when the thermostat was in.
