The Cadillac Fleetwood is a model of luxury cars manufactured by the General Motors corporation from the mid-1950s through the 1996 model years. From 1927 onwards it can also refer to various Cadillac models with Fleetwood bodies.
The Fleetwood Brougham was considered the top of the line Cadillac, but without its exclusive longer wheelbase, was now virtually identical to the lesser Sedan de Ville. Other than the name, there were only subtle exterior differences between a Fleetwood Brougham and Sedan de Ville. The interior of the Fleetwood was more plush and offered more features as standard.
In 1980 the De Ville and Fleetwood Brougham were given a new body style with a squarer look and more formal roof line. The basic dashboard design was retained. Also new for 1980 was a two-door Fleetwood Brougham, which was based upon the Coupe de Ville but featured an exclusive formal landau vinyl roof.
Both the 425 and 368 are small-bore versions of the durable 472 (which was introduced in late 1967 for the '68 model year). The larger 500 had the 472's bore but a longer stroke. This engine family was the last Cadillac cast-iron engine, and the last 'big-block'.
All subsequent engines were from Buick (the short-lived 252 cu in / 4.1 liter V6), Oldsmobile (the 350 diesel and 307 gasoline V8), and of course Cadillac itself, with its troublesome "HT-4100" small block V8, an alloy unit with cast iron cylinder liners.
