Not sure where this data is supposed to be impressive really... My 496 BBC is a mild build and runs over 4800 ft/min, I would never claim I run a race engine. This is not max piston speed either but max average piston speed right? Max speed of my example peaks well over 10K ft/min. More impressive as GXP noted is the ability to handle the accel/decel loads on the pistons of high revving engines experience. Good crank and pistons help here but quality well engineered fasteners are the unsung hero.
