True. It's all a question of definition. Assembly quality wasn't all that good back in the day with many engines just slapped together (across all brands I guess).
Now everything has made a leap in quality, also thanks to computerized equipment with people who know how to run it (exceptions apply of course!).
It sure looks that Blueprint is making heavy use of modern machinery as well... and while an engine can definitely be built to insane levels of craftsmanship this seems to be a really good bang for the buck.
