^ What Jay said. I wish we had done that a few weeks ago when we pulled the 428 and C6 together.
A friend let me borrow a 2 ton engine hoist, since we had to raise that engine/trans assembly quite high. I cleaned the surrounding paintwork (fenders, cowl, etc), put down clean shrinkwrap, and put moving blankets over all surrounding surfaces. Even with all of the clearance we could get, it was still tight getting the transmission out without whacking the crank snout against the radiator support. We had to remove all pulleys, the damper, etc to clear, but again the car was sitting flat on the ground. Had I done what Jay suggested, I bet it would have made life much easier.
We did totally remove the headers before pulling the engine/trans though as some of the primaries would have posed an issue vs steering components. I did not have to disconnect the idler or remove the pitman arm because the headers weren't present. I don't know what brand I have, but they are crazy even for equal length, individual primaries.
Previous to this car, on mod-motor Mustangs, I would simply drop the k-member and lift the car off of it on a 2-post.
Also these helped prevent a mess:
