engine overheating and now it turns over but will not start?

I have the car listed above LT, we were starting to have some overheating issues, so we replaced the water return jacket and the thermostat. We filled the car up and let it run up to temperature. Everything was good. My sister took off at it went about 5 Miles and it started to overheat. She slowed down to pull into a church and park, and did it shot up to hot real hot like in the red on the temperature gauge and then it shut down. we let it cool down completely. We filled it full of water, but we towed it to the house, it didn't filter full of water and tried to start it again. all it does is turn over and the starter makes like a whining noise like no compression or nothing it just slowly turns over like the starters dragging.
