Some Volkswagens and Ferraris have aluminum engines
Because some cars have bigger engines some have all aluminum engines some have solid axles in the rear vs independent rear some have steel rims some have aluminum rims some hold more gallons of gas then others some hold more oil.
Most engines are made of cast iron, some are aluminum alloys those are pretty much the primary materials used for engines. presently engines are designing with plastic. These engines are used in racing and high end cars.
The block would be either cast iron or aluminum. The heads are typically aluminum, although some still use cast iron (particularly diesel engines).

Internal combustion gasoline or diesel engines power cars. Cars are also powered by electric motors.

If the train had 96 cars and one engine for every 24 cars, you would divide the total number of cars by the number of cars per engine to find the number of engines. So, 96 cars divided by 24 cars per engine equals 4 engines. Therefore, the train had 4 engines.
Chevrolet funny cars use V8 engines mostly. These engines are designed for high performance cars like the Chevrolet, Ford, and the Chrysler. A lot of the funny cars used the 426 cubic inch Hemi produced by Chrysler.
