The Rover v8 engine, originally designed and produced by General Motors but later on produced by Rover in the UK, is a compact v8 combustion engine. It also has an aluminum cylinder block and cylinder heads. The Rover v8 was introduced in 1967 by Rover and ever since then, it has not only been used by Rover but by other manufacturers for use in their vehicles as well. It has been around for quite some time which most likely means that it had its firing orders changed from time to time.
