Not Ranked
Not my choice for a motor in a Cobra, but Ilmor makes a marine version rated at 720hp. The motors are well liked in performance boating community, and have been reliable. This is with no supercharger or turbo either. I think the motor has a lot of potential, and IMO sounds pretty nasty with the right exhaust.
