Just got a 95 2500 4l80e 4x4 Chevy truck that had a 6.5 turbo in it. It was removed by the previous owner and I have a 6.2 with only 9000 miles on it here out of a 86 cucv. What do I need to do to get the 6.2 to work with the 4l80? I have none of the original motor or parts. Any help is greatly appreciate.
