Welcome to LS1truck! You'll love it here! Nice lookin truck--sounds good too! Not bad for a 4.8L... In the vid, I felt like I was hanging out the window for a while... I would almost scrap the idea of modding the 4.8L on a heavy ECSB 4WD truck. If you want performance, I would skip it all and jump right up to a 6.0L. Start out with bolt ons and a cam--and see where you get on all motor. From there, then you should decide wether you should go with a Procharger...
