My point is that the original equipment engines are being dismissed as "unreliable" or "unsuitable" for modern driving, which just isn't the case. I'm also pointing out that just because something is "modern" doesn't necessarily make it better.
Now don't get me wrong, I have no problem with driveline swaps and modern engines, only pointing out that a modern engine can fail just as easily as a vintage one.
Not trying to start an argument.
