Actually you dont. I've pulled a locked up big block 400 a few years back. Lift the car and support it on jack stands as high as it can go that will still allow a hoist to lift it out, lift the engine and trans out through the engine bay, then once it's out, simply un bolt the bellhousing from the block and pull the whole trans back and out of the toque converter, then you'll be able to get all the bolts out for the torque converter.
