Yes, the block can, but the internals cant. I know many will say the internals are good for a good amount of power but take it from someone who is finding out the hard way, and russell ill be calling you soon, the internals will fail. Mine did ya the block is fine but im screwed out my mind cause the previous owner blew a ring on the #6 cylinder and im paying up now. I believe Russ and his crew on the block being able to handle over 500hp i know they know their stuff but im just guessing you mean the motor as a whole.
