Cadillac V8 engine
The term Cadillac V8 may refer to any of a number of V8 engines produced by the Cadillac division of General Motors since it pioneered the first such mass-produced engine in 1914.
Most commonly, such a reference is to one of the manufacturer's most successful, best known, or longest-lived 90° V8 engine series. These include the pioneering overhead valve 331 cu in (5.4 L) cu in introduced in 1949, made in three displacements up to 390 cu in (6.4 L); a 390 cu in (6.4 L) introduced in 1963 that grew to 429 cu in (7.0 L); and a 472 cu in (7.7 L) introduced in 1968 and enlarged to 500 cu in (8.2 L). Also notable was the Northstar, which debuted in 1992 as a 4.6 litre, and was also produced in 4.4 L and 4.2 L versions.
When the Northstar engine series ended production in 2010, it became the last General Motors division to retain its own proprietary V8 design. This changed when Cadillac created the twin-turbo "Blackwing" engine in 2019.
The Type 51 was the first Cadillac V8. Introduced in 1914, it was the standard engine for 1915 Cadillac models. It was a 90° design with an L-head (sidevalve) configuration and was water-cooled. Bore and stroke was 3.125 in × 5.125 in (79.4 mm × 130.2 mm), for a total of 314 cu in (5.1 L) of displacement. Output was 70 hp (52 kW).
This engine was designed under the leadership of Cadillac's chief engineer (1914–1917), Scottish-born D (D'Orsay) McCall White (1880 -), later a vice president of Cadillac. Hired by Henry Leland for his V-engine expertise from his employment as chief engineer at Napier, and previously Daimler at Coventry, he was later to move to Nash with LaFayette. White was appointed to a committee of three to supervise the development of the V12 Liberty aircraft motor, that later contributed to cross town rival Lincoln Motor Company introducing the Lincoln L series much later in 1917.
The engine was refined for 1923 with a crossplane crankshaft that introduced the (now standard) 90° offset for each pair of cylinders which improved balance and smoothness. Power was up to 83.5 hp (62.3 kW).
The L-head was on the Ward's 10 Best Engines of the 20th century list.
