Hey guys! This is gonna be a thread to document the progress on my Sierra, it's called a bucket of mixed emotions because it's been up and down with this thing since the day I bought it. It's a 2003.5 ECSB 4wd GMC sierra work truck edition, it was a municipality truck I bought for 3600 bucks. The truck had 175,xxx on it when I bought it, it was a 5.3, 4l60e truck. What I have done since I have bought it Swapped rubber floor mat out for carpet picked up a full length 03 center console for 14 bucks need to get a couple parts for that before i put it in 2006 4l70e out of a TBSS Shorter stock antenna Color matched grill emblem cleaned interior and added some memphis door speakers pulled the 2" lift block out of the back to level it out intake manifold gaskets/pcv valve/air filter DDM Tuning 35w 5k hids (in the stock housings) To-DO Finish building the sub box tint front windows fix the little bit of rust on the truck get fogs upgrade to bose door panels I was gonna lower it but I have had 6 lowered trucks, I decided I am gonna lift this thing. I saw another thread on here and i love the lift on the truck it's gonna be a 4" spindle in the front and 3" block in the back and a 1.5" body lift build rear end build a new short block for the truck, the current 5.3 is a ticking time bomb has had a cracked 706 head for years. I'll add photos later when photobucket stops doing maintenance - - - - - - - - - -auto merged double post- - - - - - - - - - If anyone needs info on the difference between the 4l60e and 4l70e and what it takes to swap it feel free to ask.
