You said 'top end' rebuild. I assume the case wasn't split? Therefore we're talking stock oil pump, perhaps some wear on the bottom end, no oil squirters, no re-bush of rods, etc.

Certainly looks 'well dressed' and clean which helps. Specs on the rebuild (like head work?) and a detailed list of replaced and machined parts would improve the value significantly. As-is without documentation I would say a $4k-$5k is a fair value. You could up that significantly by providing compression, leak-down and documenting the extent of the build. With well-sorted documentation it could perhaps push $8k+.
