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.
