Everyone with oil temp issues

I would venture to say had I pushed it a little longer time wise, and/or approached redline, I would have hit or slightly exceeded 260. I guess the 64 thousand dollar question for me is "are the internals used in the engine up to these temps for prolonged amounts of time, and what would constitute prolonged time"? I remember reading in another thread about the bearings not being as hard nor resilliant as they used to be, as a result on changes in the metalurgy brought about by environmental standards. I would love an engine expert to chime in or be consulted as to just how high of temps this engine will tolerate and for what length of time. That would answer alot of questions for those of us that don't track the car, but still enjoy driving it the way it was meant to be driven, and live in hot climates.
