Is a SSV a V8?

Excuse me, I'm a bit confused about a technical matter related to engines. I've heard the term "SSV" being used in some automotive discussions, and I'm wondering if it's related to the more commonly known "V8" engine configuration. Could you possibly clarify whether an SSV is a variant of a V8 engine? If not, could you explain the main differences between the two, perhaps highlighting any distinguishing features of the SSV that set it apart from a traditional V8? I'm just trying to get a better understanding of the terminology and engine types involved. Thank you for your assistance.
