Of course - planting an aircooled mill back into the car takes all of 30 minutes tops with one trolley jack, a large piece of thick flat wood and some basic tools.
Before planting this engine back into the car try to start it with a powerful drill machine on the pulley with the engine resting on a tyre, if your mechanic is a VW one, get him to install the dog type crank pulley bolt - its the kind that allows a starter handle to be used, it will make the engaging dogs slip out when the engine fires.
Once it fires you know that the engine is good put the engine back in the car - now get to isolating the problem that is the starter motor bad or the transmission is lugging the engine really really hard. Isolate the engine by pressing the clutch when cranking.
