Probably not for very long.
I would be just as worried about the accuracy of a distributor type ignition revving that high.
Focus on power goals instead of how high you can rev. High revs put an incredible amount of tensile stress on the rotating assembly, so if you don't have to rev to the moon to make the power you want, it will be better for the long-term reliability of the motor.
