340ci vs 360ci engine

... Well i've been thinking and I might look into buying a Charger without a motor. I've found 3 of the and the bodies are good. They all were around 1200. They all were 318's. If I could buy one of them I could buy a 360 then put that in there right? racekilla is that a cuda? What year and make is it I like the look of it!
