-1 for the PCV delete, -1 for the evap delete, -1 for the EGR delete, -5 for the wiring, -10 for a GE block with what I presume are OEM internals (-40 if it's got OEM GE pistons), and - another 40 if they didn't install at least the factory oil cooler.
Not a terrible deal overall. You could definitely part it out for more than you paid but I wouldn't put much more into it... or you'll be in for more than it's worth real quick... There's a reason they sold it to you so cheap.
I would usually rather buy a MA71 in need of a rebuild than someone else's project MA70 with a GTE swap.... They NEVER do it right and ALWAYS seem to cut corners.
