I recently reinstalled my rebuilt 429cj and C-6 transmission in my car. I did it myself. I did not move the car, I moved the hoist, no big deal... I did not have a professional tilt mechanism on the end of the hoist, just a chain and hook on the end of the standard 2-ton engine hoist. For me the scariest part was lifting the assembly over the rad support. It maxed out my hoist height capability at the time. I had the car on a scissor type hoist, wheels off and lowered the car so that the brake rotors were a few inches off the ground. Once you get the assembly over the rad support and start lowering, it was just a matter of angling the transmission so that it would not hit the fire wall and she slid right in (well, not quite, but we got there...). Good planning, a good hoist, safety first, you are good to go.
