The Lycoming O-360 is a family of four-cylinder, direct-drive, horizontally opposed, air-cooled, piston aircraft engines. Engines in the O-360 series produce between 145 and 225 horsepower (109 to 168 kW).[1]

Design and development
There are 167 different models within the O-360 family of engines, with 12 different prefixes. This includes:[2][3][4][5]
- O-360 carbureted horizontally opposed engine series
- HO-360 horizontal mounted engine series for helicopter installation
- LO-360 identical to the same model O-360, but with the crankshaft rotating in the opposite direction for use on twin-engined aircraft to eliminate the critical engine.
- TO-360 turbocharged engine series
- LTO-360 turbocharged left-hand rotation engine series
- IO-360 fuel injected horizontally opposed engine series
- LIO-360 identical to the same model IO-360, but with the crankshaft rotating in the opposite direction
- AIO-360 inverted mount, fuel injected engine series
- AEIO-360 aerobatic, fuel injected engine series
- HIO-360 horizontal mounted, fuel injected engine series for helicopter installation
- LHIO-360 left-hand rotation, fuel injected, horizontal-mount helicopter engine.
- TIO-360 turbocharged and fuel injected engine series
The O-360 series all have a displacement of 361 cubic inches (5.9 liters). Bore and stroke are 5.125 and 4.375 inches (130 and 111 mm) respectively.[2][3]
The O-360 has a factory rated TBO (Time Between Overhaul) of 2000 hours.[1] They have been installed in thousands of aircraft including Cessna 172s, Piper Cherokees/Archers, Grumman Tigers and many home-built aircraft.
By increasing the cylinder bore of the O-360 by 3⁄16 inches, the engine was developed into the 210 hp (157 kW) Lycoming IO-390.[6][7]
The first O-360 certified was the A1A model, certified on 20 July 1955 to United States CAR 13 effective March 5, 1952 as amended by 13-1 and 13-2.[2]
