You're asking about the displacement of a 5.9L Dodge engine, which is often referred to as its "cubic inches." Here's how to calculate that:

Conversion:

* 1 liter (L) = 61.0237 cubic inches (cu in)

Calculation:

* 5.9 L * 61.0237 cu in/L = 359.94 cu in

Therefore, a 5.9L Dodge engine has approximately 359.94 cubic inches of displacement.

Important Note: Engine displacement is the total volume of all the cylinders in an engine. It's a measure of how much air and fuel the engine can ingest during each combustion cycle, which directly influences the engine's power output.
