small block to big block

Dropping the car over the drivetrain is a good way to go. I've done it both ways, but it is always easier with the steering column removed, whether you're coming in from the bottom or top.

Don't automatically choose Schumacher mounts for a 73-76 V8 k-member. Building your own DC k-member is fairly simple and doesn't cost much. Then you can use factory mounts. This is the way I have gone on every big block a-body we have built, plus I've probably built 30-40 k-members for other folks.
