For sale is a REBUILT Detroit 6-71 Diesel engine still on frame. It was professionally rebuilt by Mike's diesel (see tag). Complete rebuild top to bottom. The company that ordered this costly rebuild received the diesel, "never got around to" do anything, the crane rotted away and was replaced, and eventually I purchased this engine. It is missing the engine dipstick and also there is no fan, no alternator, and other accessories. The only things you get is what you see on pictures and NOTHING ELSE. This is a non-turbo engine, naturally aspirated, the most long lasting of all Detroits.
