Once you are ready to remove the engine, take it easy separating the flywheel from the torque converter. You want to move the engine forward to clear the torque converter studs. If the converter comes off with the motor, it will dump ATF all over the place. Worse yet, you could cause damage to the transmission input shaft as you jack up the engine if it’s hung up.
I pulled my first engine last winter. As stated above, take the time to bag and tag EVERTHING as you take it off. My engine was out for three months during the rebuild and if not for bagging and tagging, I would still be working on putting it back in.
Also, on my big block, I dropped the cross member. That really helped.
