L89 was not an engine option. It was an aluminum cylinder head option that required ordering the L78 engine. Factory docs for those cars always list both. The L78 total includes the 311 L89 cars.
LM1s are not COPOs, it was an RPO. Not rare, 10,406 built in the 4 months of availability. It was odd in that it required an optional transmission; the MC1 HD 3-speed was the cheapest at $79 and was dropped as an option at the same time.
