...how hot can a 440 big block get? (Before you cook it!) I have a 1974 Dodge Challenger that sits beautifully (in heavy traffic) at 180, it stays there for about 5 or 10 mins, then goes up to about 205 quite quickly . Cheers!

Jimmy, you have two posts going about this. I and others have replied in your other one. You might want to delete this one.

205 is not hot, that's about normal
260 is hot
todays fuel is designed to burn at a min of 195 degrees engine operating temperature
All engines require 15 degrees of timing BTDC, about 34-36 total and 195 degree thermostat
It's 2020 not 1970

212 is the boiling point , add antifreeze & it rises to about 220 , add 16 PSI to the system & 265* is the boiling point with 50% coolant
I agree 206 is well within the operating range , I would be getting nervous above 240*
It is nicer to keep it on the cooler side

yep, 205 is ok. It's the 'getting to 205 quickly' that has me a little concerned. If it stays at 205 in heavy traffic on a hot day, then you have no worries. If not, then you need some help.
