I personally make, paint, and ship these Chrysler / Mopar Engine Blocks. They are make from printed plastic and hand painted silver. They make a great Automotive gift for and Mopar Car Guy, Car Salesman, or Mechanic. I find that they work well as a business card or pencil holder, but I have seen people use them for tools and brushes as well. If you have any questions about this Mopar V8 Engine Block or would like to know more about my other automotive gifts and car item feel free to message me.
