only problem with one of the blocks is its blown but most internals are fine and as a for the second block motor the whole thing is in running condition but the tensioner bolt hole needs to be filled and redrilled and tapped.. the bolt broke inside we drilled it out and retapped it but the whole is not str8 so the tensioner does not fit correctly therefore the cam skips. its a lil work .. but best offers on any of the parts..
