What is the difference between IO-360 and O 360?
The IO-360 180 HP engine that vans sells is basically the same engine as the O-360 except the engine is fuel injected but also has a horizontal sump( the fuel injection is mounted horizontally instead of vertically) This engine actually produces more power that it’s vertical sump counterparts. The Lycoming (L)IO-360-M1A is a fuel injected, direct-drive, four-cylinder, horizontally opposed, and air-cooled with a down exhaust. This engine is supplied with a starter.
