Too Hot

He’s not using a “modern” engine with knock sensors and EFI.

While pump fuel is formulated to be EFI friendly at the expense of carb fuel requirements.

I generally use compression ratio to determine what the coolant temperature should be.

Anything over 11:1 gets a 160. 10-10.9 is 180. Under 9:1 gets a 190.

Just because a “modern” car runs that hot doesn’t mean these cars should.

195 is not hot but you old guys go on keep thinking that 60's bs and runs your engines too cold.

Years of going very fast using modern instrumentation and tuning cars that will beat up whatever you m:steering:ight be driving tell the truth. Put a wideband af meter on these cold engines and show the logging data....
You will be surprised...
