2 bbl might have been a Rochester model. Also a great source would be

A '77 Chrysler Le Baron would be the same as an 82, 83 2bbl Dodge
Diplomat or Chrysler Fifth Avenue. All have the same body style, they
are "M bodies".
In California because of very stringent rules about smog modifications

rules. Problem is lean burn computers are often faulty and don't do
the job properly and you fail sniffer test; though you won't have
visual/tampering failures as long as all the hardware is on correctly.
