Compatibility:
* Engine Block: The 22R engine block itself should be compatible. The major differences between the 1982 and 1987 22R are mostly in emissions and fuel delivery systems, not the core engine.
* Transmissions: Make sure the transmission from the 1982 truck is compatible with the 1987. The 1987 might have a different transmission.
* Accessories: Check for compatibility of accessories like the alternator, starter, and power steering pump. Some parts may have different mounting locations.
Potential Challenges:
* Emissions System: The 1987 4x4 has a more advanced emissions system. You may need to adapt parts from the 1982 to make it work, or use a different exhaust manifold and catalytic converter.
* Wiring: The wiring harnesses for the 1982 and 1987 may not be identical. You might need to modify the wiring harness to connect the 1982 engine to your 1987 truck's systems.
* Computer Control: Depending on the configuration of your 1987, it may have a computer-controlled engine. You'll need to make sure the 1982 engine is compatible with the 1987's computer system.
Recommendation:
* Get a Detailed Inspection: If you're considering this swap, it's crucial to have a mechanic inspect both the donor engine and your 1987 truck. This will help you determine if there are any major compatibility issues.
* Research Thoroughly: Online forums and resources can offer a wealth of information about 22R swaps.
* Be Prepared for Modifications: This is not a simple bolt-on swap. Expect to do some modifications and troubleshooting.
Ultimately, whether the 1982 engine will fit depends on the specifics of your 1987 truck. Consulting with a qualified mechanic and doing thorough research will be essential for a successful swap.
