How much power can a 440 block handle?

Ok I need to know whe weak points I'm looking to build a 440 stroker and going to hit it with boost. Hopeing to see at least 1400hp. let me get your thoughts on it. I'm looking to drop the hammer on a complete motor and trans, but if the block won't handle the power I'll have to look someplace else. I have not looked at casting numbers on the block yet, so I can't give that info just assume it's the weakest 440 casting. Next question will a 440 source stroker kit handle the power or do I need to look elsewhere? If so where? I'm a modern Hemi guy this big block thing is a whole new animal to me.
