The money MAY be in the turbo. Before you commit to it the turbo would need to be looked at closely. Although I'm feeling its also a 6.9 because of the front injection pump gear cover too. But any cover can be installed on any idi engine. Reading the block serial number of checking the head bolt hex size will clear up exactly whats up for sale. Clearly this has been sitting for some time if catus can grow up behind this engine and the other engine in the back ground. Really the engine should have been sealed up so no bugs, rats or moisture gets in. Just a $3.00 tarp is never really enough... Its still worth a closer look...
