"The normal running temperature for most classic GM V8 engines is 195°F to 220°F" - true at that temp it does not require much tuning and cats may light off quicker so the factory likes for warranty periods. OTOH I keep cars for decades and run non-computer cars at 160-180F and computer cars at 180-190F (have to reprogram fans) for years and find that EVERYTHING under the hood lasts longer.
