Is it possible to swap your engine to change it from a v4 to a v6?

If it is how much work is it, as in how long, and cash?Is it possible to swap your engine to change it from a v4 to a v6?possible yes.......money and time would depend on vehicle yr/make/model.....bottom line it usually is cheaper to buy v-6 version in fact it is usually cheaper to buy 2 v-6 cars than to swap it....
