I just love that roar and snorting and burble on overrun. example here.

The side oiler block is just the the latest and greatest vaiation of the 427 FE engine family. The unique sound is the product of cubic inches, compression ratio, cam timing and finally the exhaust system. The side oiler also has a higher nickle content in the casting and is a slightly stronger block.
You can get very nearly the same sound from a center oiler 427 or 428 or nearly any well built FE engine.
