is this block unusable???

[75chev4x4]

Hey guys found a 400 sbc block that I wanted to possible pick up cheqp and put away to build sometime when I have the cash. I know these are getting harder to find. Found this one but looks to have had a rod break loose and messed up the bottom end. Does it look usuable still or is it just a boat anchor? This is not mine but I was thinking about buying it if u guys think its still good, thanks.
