Could it possible?

Alright to all you major motorheads who know their shit about swaps......i gotta question.

Could it be possible to fit a V8 in my car.....I recently saw a ford focus engine which fills the space up in its engine bay pretty good, and they fit a V8 into it. I was wondering if I could possibly do the same with mine. If it is possible or could be possible, please let me know what kind of engine you think could possibly fit. thanks.
