Had a chance to work with Seth Bruton IV Works Restoration installing a new LBZ harness on this Duramax and Allison 6 speed.
We were grinning ear to ear when this thing fired up and settled into a smooth idle.
Twelve years of building Duramax harnesses and hearing one of these engines run for the first time never gets old.
I took a bunch more video and will post them as time allows.
