grab the entire thing at one time (tc,trans,engine)...it has to come out kind of steep but it will. Its heavy....I would make sure you have at least one friend helping to make things easier. You might want to go by somewhere and get a few sharpe markers and labels (with the strings) to mark any wiring that's important to keep up with. Easy to do when you disconnect...hard to figure out later one sometimes. A/C wire, Coil wire, I used Coil + wire for ign on signal, and coil - wire for tach signal patch, then I used a relay off of OEM Toytoa A/c wire to feed relay which then powers GM A/C compressor.
You may also want two of those adapters for the p/s (gear/sector) that allow you to run A/N hose.
We used some string across the fenders when we went back in with the V8 to gauge the height of the engine as I wanted it high as possible but obviously clear the hood so it could close. While mine is a 5.7... I blocked and removed EGR and I don't run converters and don't run the rear 02 sensors.
I like the configuration on the 5.3 and 6.0 engines...nice. The 5.7 Vortec is ok but kind a 5.7 bottom end + a half-baked Fuel Inj. on the top end. I'll run the 5.7 until it goes BOOM or I sell it.
