From K2500, 5 speed truck. Engine runs really well, no smoke, noises and runs smooth. I am selling just the engine long block (I am keeping the injection, sensors, and accessories. This would be a great replacement for a tired TBI engine (just need intake), or drop in for another Vortec 350/305. $350.00 OBO, will ship but would rather sell local. Can hear run (although, I need to pull it soon).
