Narrative:

As I was flying in an easterly direction approaching the santa ana canyon; where highway 91 and the 241 tollroad intersect; I saw a mooney to my right side traveling in a southwest direction away from me. The mooney was at least 1;000 ft lower than my altitude at this time. I looked for other aircraft in my vicinity; then looked back at the mooney and saw it in a climbing right turn; traveling much faster than me. I watched the mooney continue its turn for several seconds; but could not spot the mooney. As I was about to announce on corona's CTAF that I was approaching prado dam; I suddenly saw the mooney appear from under my left wing. The mooney was on the same heading as me; less than 50 ft below my wing and its horizontal axis was about 10 ft left of mine. It was traveling much faster than me; still climbing; and moving across my path from left to right as it turned southeast alongside the mountains. As the incident developed; all my attention was diverted to the mooney; and not knowing what it was going to do next; I kept a continuous watch on it as long as possible. As a result; I failed to keep track of my aircraft's position relative to the class C airspace before I turned southeast; and may have drifted into controlled airspace. I then continued my flight.
