Only difference tween the S/T 4.3 and the C/K 4.3 is the exhaust manifolds, they fit in closer to the block on the S truck. The ACC drive is the same as well because I've swapped both ways when I had a lot of spare parts, I used to rebuild both the small and big trucks from wrecked and had probably 30 or so S trucks on hand for salvage and tried to keep around 15 to 20 full sized for salvage at the same time. They are almost all gone now as I used up a bunch of the parts and crushed the rest[I built like 15 trucks in a row without buying outside parts other than windshields]. Trucks are way too high to have salvage like that laying around now. Jim
