* Specific 302 variant: While the displacement is the same, there are differences between various 302 blocks over the years. Some may require slight modifications to the accessories or mounts to fit perfectly. The year of the 302 long block matters.
* Modifications to the donor car: The engine may have been modified in the donor car, altering its dimensions slightly.
* Accessories: The accessories (alternator, power steering pump, etc.) might require some adjustments depending on the year and configuration of the 302 long block and the existing accessories on your 1992 Mustang.
In short, while it's *highly likely* a 302 long block will fit, a direct swap without any adjustments is not guaranteed. You should carefully compare the engine block's dimensions to those of the original engine in your 1992 Mustang to ensure compatibility. Consulting with a mechanic familiar with Mustang engine swaps is highly recommended.
