I just purchased a rebuilt 455 with Hypereutectic Sealed Power pistons and stock rods. I want to duplicate the 455 Car Craft Built with E-Heads and Comp XE-274 cam. This engine had 500hp and around 580ft lbs of torque. This engine peeks at 5200rpm. Will these pistons live at this level of performance with street and seldom strip use?
