Well, the email dialogue with Comp Cams Customer support went like this:
Hello,
>> I have a 2008 Trailblazer SS with the LS2 engine. It has stock exhaust
>> system and stock converter. The truck comes stock with a 410 rear gear.
>> It weighs 4600 pounds. This truck is 99% a daily driven street truck. I
>> hit the drag strip only once or twice a year.
>> I would like to upgrade the cam for more power without changing the
>> exhaust or converter. At this point I have no plans to change the heads,
>> exhaust, or converter. Can you suggest a cam and kit that will work within
>> these parameters and give me some idea of the total out-the-door cost to
>> me. Also what power increase can I expect from the cam and kit.
>> Many thanks,
>> -Walt

> I was hoping for a bit more from you. Is this my only option? Will it effect my gas mileage? What other components are required? How much will it cost me in the end? How much power can I expect with stock exhaust? Will I be able to feel it in the seat of my pants? Tell me, as a cam specialist why you chose this particular cam for me. I'm technically competent, but I'm not good enough to evaluate cam specs and make a choice. I guess that's why I call on you. Have I selected the wrong cam company? I heard that Comp Cams was one of the best.

Well, I don't know any more than I can read, and I've done that. From what I can read, it looks like it might work well. However, I read where guys are using it in vehicles besides trucks and it made me wonder if it will work just as well in a 4600 pound vehicle with a 410 rear and stock exhaust. Heck I don't know. I guess I'm just frustrated because I can't really tell you how I like it or give you what you need from me. I'm also frustrated, because you seem to be not addressing the kind of things I'm Interested in knowing. Maybe email is not the best way to get going on this.
Let me know what you think.
