LS swap into 1996 GMC 1500 2wd truck
I'm relatively new to this site and have some questions.... I am wanting to do a LS swap into my sons 1996 2wd 1500 truck. I have just put a rebuilt factory 4L60e in the truck. At the time I did this I didn't have a LS swap in mind. I'm wanting to build a 6.0 iron block (stock bottom end) with a good set of heads, mild cam and headers, factory car style intake and injection. Wanting around 400+/-hp. will my current transmission work with this engine and what do I need to do for the wiring/computer/fuel pump to make it work? or would I be better off to pull a 6.0 engine/trans/wiring from a salvage truck, I realize the truck transmission would be a 4L80e or maybe find a LS1, 4L60e transmission and wiring out of a Camaro or Trans Am? I have above average mechanical ability but haven't messed with the LS stuff. Any help would be appreciated. Which way would be the most economical way to go?

I have the Chevrolet version of this very same truck and have been looking into the possibility as a future project. So I can share some of my research but not any personal experience.
Lots of build threads at LS1truck.com including this step by step sticky on the swap you are considering.
Another document I found helpful was at the Street and Performance website documenting a LS1 swap into a 96 Tahoe.
I believe on the 1996 and newer trucks there are several things that make this swap fairly simple. The 4L60E transmission in your truck should just plug into whatever LS harness you end up using. Also, the fuel pump in these trucks puts out 60 psi so no fuel pump changes are required.

I'm currently putting a 6.0 in my 92 GMC reg cab. I don't have experience with those transmissions but I hear higher power levels are an issue with them holding up. As said earlier your fuel pump should work. I don't know about the wiring as I am going carbuerated which is a lot easier and more power for the money backed by a th350. There is a ton of info on ls1truck on the ls conversion section. Good luck

I did the swap in my 94 ext cab.lq9 6.0 with 4l80 e trans.your 4l60e will work and fuel pump to a certain hp.you want 400 at the crank or wheels? A lq4 6.0 you will need to change the flywheel to run your 4l60e.i had current performance to custom build me a harness from the fire wall to the motor.
