Lt1's have a pair of bleed off valves that have to be open while filling the coolant, and I beleive cracked open as well while running until coolant starts to ooz out.

Read up on the owners manual and it will explain the procedure on how to use these bleeder valves in the coolant system.

Sounds like you have a huge air pocket in there.

where can i find this pair of bleed off valves

One is on the thermostat housing,,,kind of hidden under the intake elbow.

The other one is inline on a bypass/heater hose very close to the first one. You will see a premolded hose coming from the water pump next to the thermostat housing, as it heads towards the radiator right in front of the alternator it turns into a short metal section, the bleeder valve will be right on top of that metal section almost directly in front of the alternator before the hose disappears again.

If you crack these open, you should see bubbles etc....while running the engine, and they should be closed only after you see a steady stream of coolant coming out. Manual will give a full explaination.
