You need to rent a hoist. There are lift plates you can attach like a carb to the manifold. You should have a back up chain to a couple other bolts as a safety as well & use grade 8 only with washers. Once you unbolt the motor/trans mounts you can roll the engine towards you straight out the front. It is far easier removing core support than trying to go over it & removing engine/trans together easier than trying to attach trans to block in car.

The battery cable for sure.

Oldsmobile used to make a 307 V8, but it has nothing in common with a Chevy V8.
