2007 Chevrolet TrailBlazer SS 4dr SUV w/3SS (6.0L 8cyl 4A)
The Trailblazer SS is an excellent all around performer. My wife loves it, and im pretty partial to it my self. Again its a great truck. Just dont hit a patch of ice (in southern Texas) at 30 mph it will send you through a fence and in to a field.
LS2, Eaton rear diff., superduty transmission, etc.
More power. It should run low 12's (or faster) in the 1/4 mile
