If you have no heat I'm leaning to low coolant.

I'm thinking you mean heat inside the vehicle.
One thing you can try, Behind the passenger head you will see two coolant lines that lead into the heater core. Remove both lines from the heater core CAREFULLY!
Get 4' of tubing and run it into the top nozzle. Turn on the water hose at a low flow rate and push the tube inside the water hose end, creating a seal with your hand. Don't turn it on full blast, as you'll pop a weld in the heater core. Water should circulate through the hose that is connected to the top nozzle then out the bottom nozzle. You may not be able to make a perfect seal with your hand, as long as there is pressure moving through the heater core you will be fine.
If water doesn't circulate through the heater core and you can't seal it with your hand, then you have a clogged heater core and it will need to be replaced.
Replacing the heater core isn't hard or expensive. Took me under 20 minutes to replace
If it the engine that is overheating you likely have two scenarios.
1. Missing waterpump driveshaft (they exist)
2. Air in your coolant system.
Lets start with air, prop the front of your car up on jackstands/ramp. Loosen the two coolant bleeder valves:

(Thank you shoebox!)
Turn on the vehicle. Once the thermostat opens up you should see steam/air escaping. Close the valves one at a time once coolant starts leaking out. I assume that your radiator and coolant overflow are full. Normally when you fill the LT1 up with coolant you should open the valves as you fill your radiator with water.
If this has been done and your are still running high temps it may be the waterpump driveshaft. Laugh all you want but the LT1 does have one. One symptom of this is that the car starts off at low temp, and gradually builds up to until it hits the red (where you should shut it off at). If this is the case, when you replaced the waterpump, you didn't remove the driveshaft off the old waterpump. Ask me how I know this
Here is what the little bugger looks like:

Unfortunately for this to be verified, you have to remote the waterpump to physically look.
Hope this helps!
