Yeah I just went by I6 decoding instructions, but I can say that:
289 is the displacement of the engine (duh)
66 is the model year of the engine
10 is the change level I think (also not sure what this means)
236-S is the engine code number which says what kind of fuel it uses and what model car it was made for.
Edit: I believe C means the Cleveland Assembly plant.
