Ihave a 2003 trailblazer 400 w big 40 mm carb,dg pipe and muffler and v force reeds.It goes like stink it just doesnt have the handling to keep up w the engine in it unfortunately.Not every one can afford a 13 grand can am,I know i cant, again not knocking the machine I'd love to try one if I could ever get my hands on one,I mean whats not to not love about 82 hp or even 62 honking horses?.I would say depending on the condition of it 1500=to probably 3 grand 3500 tops.Good luck and tell us how ya made out.My 400 can go thru some crappy stuff what gets it stuck is its weight and no 4 wheel drive.
