I just pulled the 318 out of my 73 challenger. It was my first time and it took maybe 3 hours total, and it was a lot of fun.
My first reccomendation would be to make sure you have a lot of space to maneuver the hoist. I have a small 2 car garage, and i couldve used alot more space to move around. I had to pull the engine from the side of car, not the front, so I had to remove the wheels and fender (they were alreadt off though)
Get the highest capacity hoist you can afford. Not necessarily to lift the weight, but so that you can extend the boom to get better clearance. I had to keep lowering the car because my hoist wouldnt go high enough for the oil pan to clear the fender wall. Alternatively, you could try to attach the chain lower on the block.
Use a balancing arm. This helped me enormously. Also when mounting the engine to the stand.
Get a spotter or two. You can probably do it alone, but its so much better to have someone there making sure the engine isnt going to spin on the chain and smack you in the head.
-good luck!
