To determine compatibility, you need to know:
* The specific engine code: This is usually a three- or four-letter code found on the engine block itself.
* The year and model of the Cavalier: Different years had different engine bays, mounts, and electrical systems.
* The intended use: A direct swap (same engine in a different car of the same year) is much easier than trying to adapt an engine from a different generation.
Even with this information, you'll likely need to research the specifics to ensure things like:
* Engine mounts: Will the engine fit correctly in the engine bay?
* Wiring harness: Is the wiring harness compatible, or will extensive modifications be necessary?
* Computer control: Will the engine management system work with the vehicle's computer?
* Exhaust system: Will the existing exhaust system work, or will a custom system be needed?
In short, simply stating the years of Cavalier production doesn't answer the compatibility question. You need much more specific information about the engine and vehicle in question.
