Selling 71 dart 340 engine but originally 318 car

Why because it hasn't sold in a couple weeks? Be patient and put up some better pics. You have two tiny thumbnail pics that hardly show anything other than body color.

As a seller, you need to make it as easy as possible for people to be able to check out your car. People don't like to jump through hoops for more information. Put up better pics of the exterior, interior, engine, new parts and problems you stated.
