You don't see a big block everday. Small blocks are common. I am not saying a 396 with a split block is worth investing in but in the history of the muscle car the 396 was an important motor for those who appreciate what it stood for and in this day is quite a rare find. Not everyone builds a car strictly for !/4 mile times or to be a street hero. No matter how much you spend and how fast you are there will always be someone who spent more and is faster but not everyone will own a big block, let alone a low production motor such as a 396 or 427. The 454 is a different story in that it can be made into a high displacement motor and is much more common and thus more readily available. It all depends on what you want and what you place value in. By the way, I have nothing against small blocks and agree with 90% of what you say.
