How much HP can a 77 360 block handle?

I'm putting togather a 410ci stroker using a 77 360 block & was curious what kind of HP the block can handle? Is a partial fill of hard block worth doing? Any experiance or thoughts on the matter?

I,m running about 525hp with my 410ci without hard block.Do a search for the thread about "How much HP will a 360 take" under Maddarts user name.Lots have gone up to 600hp strokers.I,m also curious about the blocks stability once turbo,s are added.Also make sure to have your block sonic checked for core shift before any machining.
