Thanks dmaxmaverick you know of any complete right ups on this type conversion with pics an some step by step stuff. I would need to use a fuel inject fuel tank out of a tbi sub correct. I put the 6.2 an all it's wiring in my 91 sub. An then discovered the motor had seized from setting almost ten years. So I figure how hard can it be to put the. Newer 6.5t in it I got a complete parts truck. But not sure what is involved to make it an the 4l80e work in the sub.
