You will need to have a flywheel or a flex plate bolted onto the crankshaft, and the starter in place. I can't think of an effective way to spin the crank fast enough otherwise. How about doing a cylinder leakdown test instead, where air pressure is put into the cylinders? You'll need to figure out a way to lock the crankshaft for each compression stroke, maybe with a piece of steel bar bolted to the crank and locked against the engine stand.
