Hello, finally starting on my 99 Silverado ECSB 1500 2wd 4.3/4L60e/3.42 NBS. I've had it since my college years and has been pretty reliable, but has had very low oil pressure and the tranny is acting up. No money for a engine/tranny rebuild, but would like to put some life back into it. Finally retired it from being a daily driver and can work on it as I have time nights and weekends. Decided to finally pull the trigger on a 5.3/4L80e swap. I know this is a NBS, but it should be pretty close to the 96-00 OBS. This is my first large project, so it's going to go slow...I'll post photos as I go along, and links to other forums that are useful. Trying to go for a stock swap/setup, where possible, on a budget. Goal is to make the truck reliable again to use it on out of town work across the state. May need to tow a 6x12 trailer, so regearing will most likely be required, especially with the tranny swap. Nothing fancy or exotic for this swap. Wish me luck!
