Engine was rebuilt but
 

Ok as my friend Aleem was doing the non sequential convsersion he noticed that one rotor housing looked ALOT newer than the other one... SWEET! but i never knew that
untill thatj ust happened. When i first bought the car i asked the guy was it rebuilt and he told me no. he played the "i dont really know much about it" but he had a crazy track ready fc sitting on a trailor but yeah the car was good for the price so i picked it up. any way back to the topic... is there any way i can find out when my motor was rebuilt?

That is going to be tough. Unless you take the car around to the local shops and see if one of them did the re-build them self’s. Other than that not sure how your going to track it down. Is it running good? Does it have good compression? Was he the first owner? Sorry bud, not everyone is very honest when they sell cars :(
