Chevy engines with a 5.0L displacement are usually referred to as "305 cubic inch" engines. This is because the cubic inch displacement is a common way to refer to engine size in the United States.
To calculate the cubic inches of a 5.0L engine:
* 1 liter = 61.0237 cubic inches
* 5.0 liters x 61.0237 cubic inches/liter = 305.1185 cubic inches
Therefore, a 5.0L Chevy engine is roughly equivalent to a 305 cubic inch engine.
