Two colleagues of mine are arguing. One says that you cannot put a Ferrari engine into another car without being a certified Ferrari mechanic. Well you can do it... but unless the mechanic was certified by Ferrari you will never get this car road or track legal.
The other says that this cannot be true because that would mean a company like Ferrari has power over the law. If you're allowed to build a mechanically safe car from scratch then why would they be able to stop you with just Ferrari engines?
