This reminds me ...
When I was a car-crazy 17-year-old who knew nothing about how cars worked, I had this old used paperback book of short car stories called "52 Miles To Terror".
One of the stories was by Bill Mauldin, the famous WW2 cartoonist, whose Willie and Joe cartoons were featured in Stars and Stripes.
The story was set in Korea, during the Korean war. A young soldier is assigned to the motor pool. He was a hot-rodder in civilian life, and a crackerjack mechanic, and is assigned to be the General's driver.
He finds a wrecked Packard, and working after hours transplants it into the General's Jeep.
A stuffy officer, perhaps the General's aide, suspects something is up and asks the young mechanic to lift the hood.
With fear and trepidation, the young mechanic does so, thinking he'll be found out and thrown into lock-up.
The stuffy aide turns out to be mechanically challenged; he looks at the shiny V8, and declares all to appear to be in order.
The general of course loves his Jeep after the "tune-up", and insists on driving it himself, so the enterprising young mechanic doesn't get to enjoy the fruits of his labour.
Anyway, the point is that with embarrassment I realized that nor would I have had a clue about how to tell a V8 from an inline 4.
Decades later I've picked up a bit of mechanical skill and a lot of tools, and can usually figure out what's under the hood.
