Hey all! I got myself a 2007 Sierra 2500HD Classic with an LQ4 (U Vin). She has 4.10 gears and a 5 Speed NV4500 Trans. I'm looking to put a nice little cam in it, but keep it reasonable as a daily driver. So far I have a CAI, single 3.5" with 40 series race and 1-3/4" ARH longtubes. Look for a nice lumpy idle and some obvious power increases. What do you guys think?
