    94 Lifted Silverado 6.0/4L80e swap Build

    Hello guys, I am finally doing my swap that I've been talking about doing for the past 2 years LOL. First off I am working with a 1994 Silverado Z71 1500 4x4. I plan on putting a 6 liter in it along with a 4l80e and swapping input shafts for me to keep my old transfer case. So far right now, I just got out my old motor, and still have to pull the tranny. But at;east I am getting there slowly. A little more about the truck...It USED to have a fresh 5.7 350 crate motor with a comp cam and performer intake with edelbrock headers, tbichips stage 3 and some other goodies. The truck has a 10" lift on it with 4.56 gears and a 14 bolt full floater with Detroit Locker. Heres a video of the old setup....http://www.youtube.com/watch?v=BqoZLWVpuFo. But for the swap this is what I plan on......

    I used a circle d 2800 converter and its perfect, and I still pull trailers all the time. I also used ls1 f body fans, they were easy to mount. Does your lq4 have return style fuel rails?

    Got the tank out today, tranny is seperated from the transfer case. Has anyone done this swap and used the Dirty dingo motor mounts that move the engine 1" backward? I want to try and make it so I dont have to modify the rear cross member

    I was thinking its the GSS340 most are using. I used the pump from an '87 Buick Grand National on my OBS truck the first times.
