Serpentine
As far as Rover V8 engines are concerned 'Serpentine' refers to the 4.0 / 4.6 age of engine design. These engines were originally produced with a Single
ancillary drive belt setup, one belt wrapping around all of the ancillaries on the front of the engine. The drive pulleys multiple grooves, usually 7.
These engines use a 'short nosed' camshaft that has a keyway groove cut into the mounting face that allows a timing chain to be located. They also have a 'half moon' shaped
retaining plate. The camshaft does not drive a distributor or oil pump.
