Been thinking about flat eight engines and their crank design / firing order. Can someone enlighten me as to the crank configuration and firing order of the eight cylinder Lycoming engine please. A picture of the crank would be great.

Are there any other flat eight aero engines?

See also a thread I started on the flat eight in the car racing world:
