Differences between aircraft and car engines (opens in new tab)

One point not covered in the SE post is that aviation engines are designed for a different and more demanding regime than auto engines. Aviation piston engines are used at or near 100% power for minutes, and 60% or more power for periods of hours.

I was doing some reading about the Mustang aircraft in WW2 and found about that they had V12 engines with 1000 to 2000 horsepower. But modern aerobatic aircraft only have around 300 to 500 horsepower. I was wondering if it would be possible to build a custom aircraft with 2 supercharged Corvette engines (around 700 to 800 horsepower each) and found this post on aviation stack exchange.
