244,000 miles on my beast, a '96 GMC K2500 only thing changed out on motor was injectors at 240,000 miles first time, oil pressure switch and obviously a PMD. I also changed the turbo to larger freer flowing one cause the gm turbos are junk and most likely would have killed my motor by now cause of high drive pressure. Im basically running an all original motor.

For piece of mind im soon gonna swap out the harmonic damper and crank pulley and possible timing set
