Like all the FX family CPUs, the FX-6350 has an unlocked clock multiplier, which means it is possible to overclock it just changing its multiplier.

However, in quick tests, we were not able to configure the processor to work stable at more than 4.2 GHz, which is the very turbo clock of this model. We did not change any voltages, which means it may be possible to overclock it if you try different voltage configurations.

Besides that, keep in mind that the overclocking capabilities of a CPU also depends on pure luck, since two CPUs of the same model can reach different clock rates.
