My 2011 Silverado has an elaborate air intake system to ensure that it sucks in the coolest air available at the time/location/environment of it's operation. The cooling is controlled by 2 sequential electric fans that are operated and sequenced by the onboard computer. Once the engine comes up to temperature and remains running, the analog temp gauge on the dash sits at 210F and never moves.
It uses a conventional, push rod, 4.8 Liter V8, MPFI and performs tasks as good or better than my older 5+ liter V8 engines of the past on today's 87 octane fuel, at 50& or better economies.....exiting purer exhaust.
I compare that to my 1971 pig Chevy 4 door 400 cu in big block station wagon weighing a couple k# less running intake air right off the belt driven radiator/tranny cooler/AC cooling fan, gasping to get up to 10 mpg if it could ever get there running a 192 or thereabouts stat.
I know a lot has changed over the years in engine design, but with today's emission/efficiency rules, apparently hotter is better.......as are lubricants to tolerate such......my 2c.

Minus two kids, we traveled light with only the youngest in tow. As long as a pool was at the end of our destination she was easy to please unlike the other two who have a multitude of requirements to travel with mom and dad. Amana Colonies served as a respite where we ate a family style lunch that sustained us with more food than could reasonably fit into our ample physiques. The show at Ankeny
