As my babies age I've decide to take an interest this year into bringing them back into better condition. The Yukon is original except the tranny which was replaced at 165K. The Suburban is all original with no major repairs. The Yukon has 202K the Suburban just turned 200K. I bought a used 5.7 from our local salvage yard and have begun rebuilding it. My plan is to change out the engines one at a time and then send off to be repainted. Been looking around for other enthusiast boards when I ran across this one. Just thought I would say hello.
