Selling a car but wanting to keep the engine

I didn't mean to imply I was putting the 318 in the Dart. What I meant was that because it was only a 318 that I hadn't been considering doing that. What I was implying was advertising it for sale with the 340 still in it so that the perspective buyer could test drive the car if they wanted but with the understanding that it was being sold without the 340. However, if an interested buyer was interested in the 318 I would certainly be willing to sell the Dart with it.
