Without additional information about why the short block was replaced, it's difficult to determine whether this is a bad thing or not. However, it's generally a good idea to investigate further and ask who replaced it (or the seller or dealer) for more information about the replacement. Some possible reasons for a short block replacement include engine damage due to overheating, oil starvation, or other issues that may have led to a catastrophic engine failure.
If the short block was replaced under warranty, it may indicate that the issue was identified and resolved by the manufacturer. However, if the replacement was performed outside of warranty, it may be a sign that there were significant problems with the engine.
Ultimately, it's important to have a trusted mechanic inspect the vehicle and provide an opinion on the condition of the engine before purchasing.
