Why??

So, does a 408 or 427 small block really sound that much different than a 427, 428 or 429 big block? Not trying to stir anything up, just seeking opinions from those with experience with both.

Yes, a big block 427 sounds much different than a small block with the identical cubic inch displacement. This is because the sound is not a function of the bore and displacement cavities, but rather from the surrounding iron (and pipes, mufflers, etc.). Think of it as a bell, a large iron bell, that tolls at a perfect pitch. The beautiful sound of that iron bell is not because of the size of the inside cavity, but rather because of the size, curvature and makeup of the bell itself. Just imagine if that beautiful iron bell was only a half inch thick -- it would sound terrible, but the cavity beneath it would still be the same.

I think a lot of people end up selling their cars because how raw they are compared to modern sports cars. They are loud, you get wind buffeting in your ears, you stink like exhaust fumes, and they ride rough (relatively speaking). Doesn't bother me, but others are put off by it after a while. My biggest problem is that I'm always finding something to upgrade or tinker with on it.
