However, there might be some minor challenges depending on the specific year of the LX and any modifications either car might have already received. You might encounter issues with:
* Wiring Harness: The wiring harness from the donor 5.0 might need to be adapted to match the LX's system.
* Engine Mounts: While the engine should fit, the engine mounts might require adjustment or replacement depending on the condition and potential variations between the two cars.
* Exhaust System: The exhaust system might need modification or replacement to properly fit the new engine.
* Accessories: The placement of accessories like the alternator, power steering pump, and A/C compressor might require tweaking.
Essentially, it's a relatively straightforward swap *if both cars are Fox-body Mustangs*, but expect some mechanical work, potentially involving modifications or replacements of smaller components. It's not a simple drop-in replacement in most cases.
