1971 dart/swinger...340 4-speed
My 1971 Dart GT came with a 318 but now has a 1972 340 in the engine bay; do I call it a "clone?" No, I call it an improvement.
Just kidding; I get a chuckle out of these different names for cars which are made to resemble something they weren't when they were built, and the people who try to sell them because now they look like something else which is worth a whole lot more than the one they atually have.
