I've never heard of a lt1 engine running at normal temp with cts unplugged and getting real hot with it plugged in.

My thought is the fans running when cts is unplugged are keeping coolant temp down. With it getting hot real fast, I suspect air in cooling system.

Go to shoebox site, link provided at end of this paragraph. He has pics of where the 2 air bleeder screws are around the water pump. Try bleeding air out and see if it makes a difference. shbox.com
