Straight-4
Chrysler introduced a straight-four derivative of their new Flathead straight-six in 1926. Initially used by Chrysler, the straight-four was fitted to Plymouth and Dodge light trucks beginning in 1929, lasting in production through 1933.
The original version displaced 185.8 cu in (3,044 cc) and produced 38 hp (28 kW). This was only produced in 1926, with displacement reduced to 170.3 cu in (2,791 cc) for 1927 and 1928. Power was initially rated the same but was upped to 45 hp (34 kW) during the 1928 model year.
After the introduction of the Plymouth brand in 1929, the base engine was enlarged to 175.4 cu in (2,874.3 cc) with the power rating remaining the same. It also equipped Dodge light trucks in 1929–1930. It was enlarged again to 196.1 cu in (3,213 cc) in 1930 with 48 hp (36 kW). The engine was slightly revised for 1931 with 56 hp (42 kW) and 1932 with 65 hp (48 kW) for Plymouth only, Dodge continued with the 48 hp (36 kW) from 1931 to 1933. A small-bore version was developed for export markets in 1931, with a narrower bore which brought the RAC rating down from 21 to 15.6 hp. For 1932 the bore was made a little slimmer yet, bringing the tax horsepower rating to just beneath 15.5.

Straight-6
There were essentially two lines of flathead inline-sixes made by the Chrysler Corporation. Chrysler and DeSoto used a longer 25 in (640 mm) block with greater cylinder spacing, while Dodge and Plymouth shared a 23 in (580 mm) block. There is one exception to this: when Chrysler established an engine foundry in Windsor, Canada in 1938, it was decided to only use the long block for all Canadian-built engines. These engines received a trailing "C" in their designation, becoming P8C for example. Thanks to judicious dimensioning, the Canadian 201- and 218-cubic inch engines had nearly identical displacement to their American cousins.[2]
Beginning in 1938, the 201 cu in (3,299 cc) inline-six was used in Massey Harris's Model 101 (later known as the 101 Super). It continued to be used by Massey until 1940, when it was supplanted by the 218 cu in (3,568 cc).[3] In 1940, Chrysler's 242 cu in (3,966 cc) straight six went into Massey's 201 Super, which lasted until 1942.[3]
The last automotive use of the Chrysler flathead inline-six was in 1960. It was replaced by the much more efficient OHV slant-6 the following year, which appeared in most Dodge trucks starting in 1961. The flathead remained in production until the early 1970s for industrial and agricultural use.
