So I decided to take the plunge this winter and effectively double my hp an torque. Now to make everything work. I will update this thread as I go, I am shooting to have a driver by spring.
2006 5.3L LS4
Trans moved forward 3"
Originally was going to run MS3, now planning on running stock GM computer.
Picked the engine up from the wrecker, 64000kms. Notice the compact water pump.
Out with the 3.0!
Initial mock up. This is where I am at, revising the transmission mounts.
