I know of 2 firsthand that are capable to spin 5000+ under light load. One is on its third set of stock rods and second crank and block due to rod failure (he insists on spinning it as fast as he can all the time), the other is on its original (he won't turn it past 4800). Luck of the draw, and how long and often you spin it that fast. I doubt they'd do very well past 4900rpms for long, but there will be someone shortly that'll tell you they're fine to 6k.

And some have come apart at 4K. Most hang out but some have factory imperfections

4800 is the average limit for long term running.
