I've seen stock blocks crack at 400hp and I've seen stock blocks hold over 600rwhp and live for a couple of years. There is really no way to answer this for you. But a lot of people say the limit of the stock block is 500hp after that it will crack I think its crap it depends on the build what kind of parts you use to build motor, and how well the whole assembly is balanced. But personaly I think it will live for a while. Oh and I forgot to mention this is with no custom chip just adjusted the timing and fuel pressure and pulled it.
