I'm sure that depends solely on the block.

No the block is fine actually. When you build an engine for forced induction there are quite a few differences than when you build it for n/a.
Besides component material the bearing gaps are different and of course the compression.
No one can predict when an engine will fail but you can know when your pushing things beyond what they were built for.
I've said it before and I'll say it again. Doing it is one thing, getting it to live for a long time is another. Then you have things like intake air temps that need to be controlled as well to add to the equation as well as the quality of the gas you just put in.
The cast piston used in these engines does not like to be treated unkindly either and when you get "pinging" under boost your doing damage as well.
There are a lot of things to consider to a reliable build, I like to take a conservative approach as it never hurt anyone to play it safe. Dancing with the devil will get you burned if your not very careful and I don't know to many people that can afford to throw money away.
