More HP in the STS would come from the Northstar, not the 6 L. Since the STS is more upscale, I think they'd try to use the higher tech engine in it, so they won't have the OHV in a 70k car complaint...cuz you know people would complain (although who know's how much the 6L in the CTS would go for...)

I disagree with the alleged naming...I've heard the CTS V Series Plus referred by a different acronym.

And it would probably match the Z06 for numbers. That's why they have those Vette Blue Devil rumors floating around
