4l80e/6.0 lq4 Envoy.
Ok , its been a while since I posted any results and info on this build. The truck was actually finished last spring. It performed very well. Lined up with a few Ss trailblazers and they found out this big SUV has ***** 😁. Over the winter of 2013 I made some more changes. I installed a revised ls9 cam, valve springs, 4l80e trans, and computer. I also have a s475 turbo and pro charger. I'll eventually install one of them. After the install of cam and springs I took it for a spin great low end torque and good power. I put my foot through the floor and the little 4l60e blew up. I installed a built 4l80e custom steel drive shaft. Instead of purchasing aftermarket 80e controller I bought one out of a Silverado with the 6.0/4l80e software. Now I'm waiting on my msd coils. There's a video on YouTube titled 6.0 envoy ls9 cam. Let me know what you think☺
