If you think a V8 in a Miata is an ambitious swap, just check out this guy's project. Yes, that's a 5.3-liter Jaguar V12, and if that wasn't enough, its fuel-injection system has been replaced with a project-car hell-worthy six-carburetor intake! Just listen to that baby purr.
OK, well, you would be able to listen to it purr if it actually stayed running. But isn't that why we take on projects like this, just to suffer the pain of anticipation? We can't wait 'till he gets it out on the street. Sure it may not be as powerful or reliable as a well-built Ford V8, but who cares? It's a V12!
