Hi enthusiasts! I have a 1978 Cheyenne K20 with blown motor and a 1994 TBI K1500 Suburban. I am planning to swap the engine, trans etc into the square body. I know I need to bring the ecm/prom and the harness to the Cheyenne, but what else will I encounter needing? Has anybody done this? Is is even worth doing? Does anybody know of a link to this project in video or otherwise. Many thanks, Gorge Gearhead
