Awesome results! I installed an ls9 cam in my 2500 Silverado 4x4. I did the cam and a pulley change on the Maggie at the same time... It felt like I put another supercharger on again! I was very impressed with the power and drivability of it. Kinda stealthy to. Not a big loapy sound so it's hard to detect. The cool thing is with your truck is every stage of the race showed improvement! 60,330 and 1320 are all better!!
