I have an excellent running 6.2 diesel out of a 1988 1/2 ton Suburban. Very clean, and has updated intake manifold. Only issue at all is that the throttle shaft has very small leak, and if it sits you will have to bleed air out of fuel system to start. Runs excellent! Will not include cruise control parts. I have videos of it running & starting, and it will be in rig for a few more days if interested in hearing it run/start in person. $400 PM me for video action!
