Hello Scotty,
Rob here. The question I have is : Overheated my Big Block now the weather here is -28c and it looks like I am a fog machine as driving down the road. Is this kinda normal? Should I pull the plugs to see if they are wet?
Those massive engines put out a lot of water vapor that condenses when it hits cold air. I would fully expect to see a lot of moisture in the exhaust when it's that cold. How recently did you overheat it? You can check your plugs, if one or more look steam cleaned, you blew a head gasket. Head to the local auto parts store and rent a head gasket test kit, follow Scotty's video on how to use it, and that will give you a very good answer to whether or not you damaged anything.
Thank you Justin for the web link will check it out.
Never use straight antifreeze. The engine will overheat.
Always 50/50 mix. Check your coolant with a $5 tester to check your freeze protection.
A cylinder compression test would also indicate if you have a failed head gasket.
Ok i will by the tester add water and set for -30

Thanks for the tip on no str8 antifreeze
Overheated last week it was -32c and the coolant had froze in the heatercore i think therefore causing a blockage or the radiator froze up. So i limped it home and shut it off then went and got 4 gallons of concentrated coolant. Poured it in straight no water added. Block was of course cold when i got back. Pulled the thermostat tested in a pot of boiling water it opened as it should at 195 degrees.
Found out also there was a blockage in the heater core. Which producing no heat. Took hoses off and switched then around to flush back the blockage.
