The factory style motor mounts should be able to hold the motor up, but I'd use a small block of wood b/t the oil pan and drag link to hold it up.
If the exhaust system is still hooked up, then you really don't need to block of wood. The motor mounts hold the weight of the motor, the exhaust will just keep it from trying to tip backwards.
