* Condition of the engine block and internals: Is it seized? Does it have significant external damage (rust, dents)? The presence of internal damage like scored cylinders or a cracked block drastically reduces value. A complete, relatively undamaged engine will be worth far more than a heavily damaged one.
* Completeness: Does it include all the necessary components (supercharger, manifolds, sensors, etc.)? A complete engine is worth significantly more than a partially disassembled one.
* Demand in your local area: The market for used car parts is regional. What someone might pay in California might differ from what someone in Arkansas would.
* Intended use: Someone needing parts for a restoration might pay more than someone simply looking for scrap metal.
Given these uncertainties, a reasonable guess for a non-running 1997 Buick Riviera supercharged engine would range from $100-$1000, or even less, depending on the state. It could be worth more if it's exceptionally clean and complete. However, it's unlikely to fetch a high price in its current state. You'd likely need to do significant work to get it running, making it a risky investment for most people.
To get a better estimate, you could:
* Check online classifieds: Search eBay, Craigslist, and other sites for similar engines to see what's being offered.
* Contact local salvage yards and auto parts stores: They can provide a better estimate based on their current inventory and demand.
* Post pictures and details on forums dedicated to Buick or classic cars: Enthusiasts might be interested, even if it's not running.
In short, without seeing the engine's condition, providing a precise value is impossible. The range above provides a realistic ballpark, but expect to be at the lower end of that range unless the engine is in remarkably good condition.
