	In early 1979 the car was re-engined with the BL O-series OHC motor. Due to a conflict of the Austin Princess and Morris Marina competing in the same market sector in New Zealand, the Princess got a 2.0 L unit mounted transversely, while the Marina (which was face-lifted at that time and renamed in NZ as "Morris 1700") received the 1.7 L unit mounted longitudinally.
