In original packaging & plastic cover.  Never opened.  

I see this description.  & sounds accurate to me:

This diecast 1/6 scale model of a Chevrolet Small Block 350 V8 Engine is a must-have for any car enthusiast. The Liberty Classics brand has created a beautifully detailed display model that is perfect for boys and girls alike. The model is made from high-quality diecast materials and has not been customized or autographed in any way. The intricate details of the model, from the engine block to the transmission and beyond, make it a great addition to any collection.
