Can 351w block handle 550HP and then add a little nitrous ????

That would depend on a lot of variables
What year block and what kind of RPMs?
Hardblocked and splayed 4 bolt caps?
Intenal balanced and light weight components?
What do you call a little nos?

RPMs and detonation are the biggest killers. You could break a late model block at 550 hp with enough detonation.
