Hi everyone. This isn't my first swap, but it is the most involved electrically wise. What I've got is a 98 ecsb with a 305 vortec auto that has a dead cylinder. SO, it's time to do something. One option that I'm HEAVILY considering is a 5.3 or 6.0 swap. I've read and read and read, and think that I have a really good idea of what I'm getting myself into, but I have questions.
1. Parts list: LS engine, harness (oe or custom built swap harness), mounts, headers or manifolds, a/c adapter and custom lines, custom fuel lines, coolant and oil pressure adapters, and flywheel spacer. Am I missing anything?
2. What accessories do I use? I know that I'd need to get the brackets with the LS motor, but do I use my old alt. and P/S pump or the ones from the LS motor. I know that I'd have to do the Sanden with a custom bracket for the A/C.
3. I've seen many different ways of running the harness (ex.: use both LS and 98 vortec computer, use just the LS computer, and a few others) Is there a "best" way?
4. I read in one swap thread about having to use a pressurized coolant tank. Do I use my original radiator or do I need to use something different?
5. Is there a way around the VATS in the LS computer other than sending it to someone to get it removed? I don't know why, but I don't really wanna ship it off if I can get away without it.
I'd like to attempt to make my own harness. I keep reading LS1truck.com's site and telling myself that it doesn't look that bad. (I used to do mobile A/V, so I'm no stranger to wiring.) Can anyone that's done that please chime in and let me know your experience?
Thanks ahead of time!
