Just wanted to share my thoughts on putting a cam in one of these trucks. I have an 05 tahoe ppv with around 150k. It started making a lifter noise so i started ordering parts. I went with a texas speed low lift stage 3, 216/220 112lsa and it comes with ls6 blue springs. Also installed pacesetter headers and y pipe. It has a k&n tube only to the stock air box. I also threw in a stock trailblazer I6 converter in it. Mostly everything else is OE. Got it all back together and street tuned and it drives amazing. From idle to 3k it drives just like stock, even with the converter locked it still feels like it has more at 2k on the highway than before. Now after 3k its a different story, it starts pulling and by 4300 your back in seat. Pulls strong to 6k and man its fun. If your thinking about a cam/stall or have a lifter making noise its one of the best decisions you can make.
