Compression ratio on 2.8?

I'm doing a lot of research to make sure I'll take my blown 2.8 well past the 200k mark without a lower rebuild, and one of the big things these supercharger guys worry about is a nice low compression ratio.

Anyone know what ours is stock?

Wow, that's pretty low, I guess I shouldn't worry too much about detonation then, huh?
