The days of “bigger is better” at Cadillac were quickly going away by 1978, as the oil embargoes caused consumers to rethink their needs with respect to their automobile choices. You can’t deny that miles of shapely sheet metal wrapping opulent interiors and powered by monstrous V8 engines is one good way to sum up a large part of Cadillacs illustrious history. The 70s decade was known for having lots of bold style, and these ’78 Cadillac models are great reminders of just that, as well as setting the standard for luxury. If you’re lucky enough to own one of these great cars, be sure to treat yours to the factory specifications and instructions it requires to live on as a beloved souvenir of that era.
This factory-written shop manual is perfect for service, repairs, restoration and rebuild projects. Clear illustrations and photos show exploded views, as well as component details, plus specifications on engine data, engine torque, carburetion and more.
