I am following this now to see what you come up with only because I just picked up a 93 2500 burb with the 454 with only 78k original miles on the clock. Clean rig and my wife has given me the go ahead to use this to replace my 86 extended cab F-250, bored and stroked 460, granny 4-speed, lifted 4" and sitting on 35"(May be selling or parting later) as our new family camping/hauling rig. I know ours are different generations but the concept will be about the same.
