* Engine Family: The 305 cubic inch small-block Chevrolet engine was a mainstay in those years and remained relatively unchanged in its basic design.
* Mounting Points: The engine mounts and other critical mounting points are likely to be compatible.
* Transmission: Assuming both cars have the same transmission (e.g., TH350, TH400, or 700R4), the engine should bolt up without issue.
However, there are a few things to consider:
* Wiring Harness: The wiring harness from the 1986 engine might not be a direct swap. You might need to modify it or source a harness specific to the 1982 Caprice.
* Fuel System: There might be differences in the fuel injection system. You might need to swap the fuel lines or adapt the 1986 system to the 1982 car.
* Exhaust System: The exhaust manifolds and the rest of the exhaust system could be incompatible. You might need to swap or modify these components.
* Other Accessories: Make sure the alternator, power steering pump, and other engine accessories are compatible with both cars.
To be absolutely sure, it's best to:
1. Consult a repair manual: A repair manual for both the 1982 and 1986 Caprices will provide the most detailed information on engine compatibility.
2. Check with a mechanic: A professional mechanic can assess the situation and advise you on any necessary modifications or parts swaps.
Overall, while it's likely that the engine will fit, it's best to double-check for potential compatibility issues before proceeding with the swap.
