i rebuilt a 5.0 in my garage for about $250. new bearings, rings, etc... honed the cylinders myself. all new gaskets. Easy as can be with a good library book (for the torque specs) and a torque wrench. took me 5 days working on it 2-3 hours a night (from in-car broke to in-car fixed). car ran another 20K miles (including 4 trips from Tampa to Memphis at 3K round-trip miles each) before i traded it in for my '98.
easy as can be
