John Moss and GM Performance had the Trailblazer SS, Tahoe SS, and the Suburban SS Lucchese on display on the 2003 Hot Rod Power Tour. The Trailblazer and Tahoe had the 345 hp 6.0 and the Suburban had a massaged 8.1. Couldn't get the HP numbers on the 8.1. Original idea for Trailblazer SS motor was a twin turbo 4.2 I-6 with 400 hp. Not sure what happened to that one. GM saving money by leveraging assets across vehicle lines as usual. That's why there isn't more widespread use of the CTS 3.6 w/260 hp. A variable valve timing, DOHC V-6 would look nice in some other platforms. Like an Impala SS, or Monte Carlo SS, or the new Equinox or the Uplander or Malibu SS.
