Ok, took today off work.
Got the power steering pump back on, plumbed up. Which required the left exhaust manifold to be on first.
Got the wiring out of the Yukon. Went fairly nice. The headlight harness is separate from the engine harness. So all I really have to remove is the ac wiring.
Took the tailshaft off the trans. Cutting the ops will NOT work. Is going to require getting the advanced adapter shaft and having a rebuild.
Pulled timing chain, it was fairly loose. Installed new one and confirmed my block is machined to be a roller. SCORE!!!
I went to change coolant fittings. Snapped one off in the intake
So Ive got to pull the intake to fix it because an easy out would not work.
