You'd find everything from small motorcycle engines displacing less than 100cc to massive truck engines exceeding 10 liters. Cars ranged from sub-compact engines around 1.0 liters to large V8s in excess of 5.0 liters.
To get a more specific answer, you need to specify the *type* of vehicle you're interested in. For example:
* "What size engines were used in 1982 American muscle cars?"
* "What size engines were common in 1982 Japanese economy cars?"
* "What size engines were used in 1982 pickup trucks?"
Providing more detail will allow for a much more accurate and helpful response.
