L-Head
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 was 3.125 in and stroke was 5.125 in, for a total of 314 in³ of displacement. Output was 70 hp (52 kW).
The engine was refined for 1923 with a new split crankshaft that introduced the (now standard) 90° offset for each pair of cylinders. Power was up to 83.5 hp (62 kW).
The L-Head was on the Ward's 10 Best Engines of the 20th century list.

Cadillac created a new V8, the 341, for 1928. It was a 341 in³ engine and produced 90 hp (67 kW). The same year saw the introduction of the synchromesh transmission. This engine was used in the Series 341 and 341B cars of 1928 and 1929.
From 1930 through 1935, Cadillac produced a version with an increased displacement of 353 in³ (5.8 L). This used a 3.38 in (85.7 mm) bore and 4.94 in (125.4 mm) stroke. This engine was used in the Series 353/355/355B/355C/355D and Series 10.
Monobloc
A 322 in³ (5.3 L) "monobloc" engine was used in 1936's Series 60. It was designed to be the company's next-generation powerplant at reduced cost from the 353 and Cadillac V12. The monobloc's cylinder heads were cast as one unit with the engine block, and it used hydraulic valve lifters for durability. This design allowed the creation of the mid-priced Series 60 line.
Bore was 3.375 in (85.7 mm) and stroke was 4.5 in (114.3 mm). This engine was modified with a 3.5 in (88.9 mm) bore for the 1936-1948 346 in³ (5.7 L) engine. This was used in the Series 60/60S/61/62/63/65/67 and 70/72/75. It was also used in tanks in World War II.
LaSalle
In 1937, the new Monobloc Flathead gained 24 cubic inches in Cadillac V-8 models to 346 in³, while the LaSalle Straight-8 of 1934–1936 was replaced with the 1936 smaller 322 in³ version at 125 hp (93 kW). In 1941, the LaSalle nameplate was phased out along with the 322 in³, and Cadillacs, all 346cid powered, were available with the new Hydramatic automatic transmission which debuted in Oldsmobile the previous year. These engines were produced through 1948.
