iv not seen inside the fazers engine but depending on amount of time and money wanting to be spent strip it and depending on damage either get it welded on maybe or woodruf key slots 'cut'in by machine shop etc there should be loads of used engines out there but they might be in same condition(or worse!) i think the fzr and thunder cat(or ace which ever was the 600cc model) are same engines and blocks but there will be more on here who know for sure,if rest of engine is good id be inclided to try repair this engine if possible,ave fun and good luck
