again, it is very hard to tell the difference with just the bare/bone engine w/o any attachment/accessories. however, assuming you bought the engine with the accessories then you will know that the 330 has the following:

purple injector. all other m54/m52tu has black fuel injectors
3.0 throttle body. 325/323 has 2.5 inch throttle body.
