I am just checking in. I am new to the LS world and need some help. I have a 2003 GMC Sierra SLT Quadrasteer 4X4 with a 5.3L. I have the hypertech III power programmer and I just ordered a CAI and I am adding a flowmaster. I am looking for the stock specs on my motor and what are the cheapest and easist bolt on upgrades I can do. What LS motors can I use parts off of to save money? That kind of stuff. All help will be greatly appreciated. I will be adding photos as soon as I can. I hope to here form you guys.
