The pilot reported that while flying at 8,000 feet msl, about a half hour into the flight, the engine missed then ran normal again. The engine power then decreased to 20 inches of manifold pressure. He stated he informed Air Traffic Control of the situation and requested the nearest airport which was 8 miles away. The pilot attempted to re-establish engine power to no avail. The pilot was able to reach the airport and the engine lost all power while on final approach. The pilot made an uneventful forced landing on the runway. Inspection of the engine revealed that the wrong pistons were installed in the engine. The pistons should have been part number 648044 (compression ratio of 7 to 1). The pistons found installed in the engine were part number 648045 (compression ratio of 8.5 to 1). The engine was overhauled on July 30, 1996.
