What temperature in degrees should a 350 chev be?

Answer 1

Between 190 degrees to 210 degrees, But no hotter.

Another answer:

In reality, the engine temperature sensor only detects the temperature of the coolant at one specific point on the engine. There are parts of the engine that are much hotter, such as parts of the head near the exhaust manifold.

While an engine functions best when "hot", it will fail when overheated. That's why they are equipped with methods for cooling and maintaining a specific temperature.

Thermostats hold the coolant inside from circulating until the temperature reaches a specific point, then the thermostat opens allowing the coolant to circulate through the radiator. until the temperature drops below the set-point of the thermostat.

Since coolant systems can build and hold pressure, the boiling point of the coolant can go well above the normal boiling point of water, and internal engine temperatures of up to 240 or even 250 are possible if the cooling system can maintain the pressure.

However, it is far better to keep the temperature below 230 if you can.

New answer; Who ever answered the question the second time needs to understand that the tempture sending unit on a small block Chevy is screewed into the cylinder head by the EXHAUST, where it is the hottest 240 to 250 degrees will warp the heads and possibley destroy the compression rings. If your engine is heating up to 230 degrees, Then there is a problem with the cooling system and you are damageing your engine and putting loads of miles on it. YOU BEST KEEP THE TEMPTURE AT 210 DEGREES AND NO HOTTER. NEUTZ.
