I pulled and installed a 300E engine w/trans by myself although I highly recommend having help.
A few pointers: Drain all fluids before disconnecting lines. Don't connect the hoist to the engine hooks as they will bend and are bolted to the aluminum head. Run some straps around the engine. The load leveler is helpful but depending on the type, it's crank will come close to the windshield since it needs to be close to the engine. If not, your engine hoist (cherry picker) may not clear the radiator over rider given the drivetrain is removed at ~45 degree angle. You may want to lower the car to the ground after you've unhooked the downpipe and motor mounts to gain more clearance. Go slowly, some connections are missed or easier removed once the engine is lifted.
