Are the hoses new? Could a hose be collapsing when it gets hot?

Maybe pull the thermostat, could be not opening all the way?

Not sure on the LT1s, Some cars you can put the thermostat in upside down which will cause it not to open all the wayas well?

Could the blade on the pump be loose and just not moving the coolant?

How about double checking the wiring on the water pump, make sure it's not running backwards? As the engine warms up the hose from the back of the heads that goes into the rad. about 1.5 " below cap should be flowing water back into the rad. ( I think only once the thermostat opens. ).
