* Engine Management: The 1987 engine likely uses a TBI (Throttle Body Injection) system, while the 1995 vehicle probably has a more advanced system, likely OBD-II compliant. The computer, wiring harnesses, sensors, and fuel delivery systems are completely different and incompatible.
* Engine Mounts: Engine mount locations may vary slightly, requiring modification or custom mounts.
* Accessories: The location and type of accessories (alternator, power steering pump, A/C compressor) might differ, requiring adjustments or replacements.
* Exhaust: The exhaust manifolds or headers will almost certainly need to be changed.
* Transmission: While the transmission *might* bolt up (depending on the specific transmissions in both vehicles), the computer controls for the transmission will be incompatible.
In short, while a small-block swap is possible, it's a significant undertaking involving much more than simply dropping the engine in. You'll need a new wiring harness, likely a new computer, and possibly other modifications to the engine, mounts, and accessories. It's not a straightforward bolt-on job.
