* 4.3L V6: A relatively common and smaller engine option.
* 5.0L V8: Another popular choice, offering more power than the V6.
* 5.7L V8: A larger displacement V8, providing more power still.
* 6.5L Turbo Diesel: A diesel option for those needing significant towing capacity. (Less common than the gasoline options)
* 7.4L V8 (rare): A very large V8, usually found in heavier duty trucks or specific trims.
To know definitively which engine was originally in *your* 1996 Silverado, you need to check:
* The Vehicle Identification Number (VIN): This is the most reliable method. The VIN contains a code that specifies the engine. You can decode the VIN using online tools or by contacting a Chevrolet dealership.
* The engine bay: Look directly at the engine itself. The displacement (e.g., 4.3L, 5.7L) is usually stamped on a part of the engine block.
Once you know the original engine, you can then determine what other engines *might* be compatible with your truck. Swapping engines is a significant undertaking and requires careful consideration of many factors, including mounts, wiring harnesses, and the transmission compatibility. Professional guidance is strongly recommended for an engine swap.
