TheContinental O-526 is a family of air-cooledflat-6 aircraft piston engines built byTeledyne Continental Motors.^[1]

Constructionally similar to the O-470 series the O-526 has larger cylinders of increased bore and stroke, giving a displacement of 526 cu in (8,620 cc). The O-526 was introduced with reduction gearing and a supercharger as the GSO-526 for theCessna 620.
