original 194 CID engine was replaced with an improved variant (the stroke was increased to ) in 1933, introduced in the Series CA Eagle. This newly revised engine put out , and was produced until 1936. Toyota's first engine, the Type A produced from 1935 to 1947, was a reverse engineered copy of the Chevrolet engine. Applications: 1933 Chevrolet Series CA Eagle / Master - @ 2800 rpm, @ 1000-1800 rpm 1933 Chevrolet Series CB/OA/OB/OC/OD Commercial Utility - @ 2750 rpm, @ 1000 rpm 1934 Chevrolet Series DA Master - @ 3300 rpm, @ 800-2200 rpm 1934 Chevrolet Series DB/PA/PB/PC/PD Commercial Utility - @ 3000 rpm, @ 1000 rpm 1935 Chevrolet Series EA/ED Master - @ 3200 rpm, @ 1000-2000 rpm 1935 Chevrolet Series EB/QA/QB/QC/QD Commercial Utility - @ 3200 rpm, @ 1000-1400 rpm 1935 Chevrolet Series EC Standard - @ 3200 rpm, @ 1000-2000 rpm 1936 Chevrolet passenger cars - @ 3200 rpm, @ 900-2000 rpm 1936 Chevrolet trucks - @ 3200 rpm, @ 900-1500 rpm 181 A () version was also introduced in 1933, in the lower priced Series CC Standard, and used again in the 1934 Series DC Standard. It made a peak at 2300 rpm, and peak torque of at 1200-2000 rpm. The compression ratio in the 1933 model was 5.2:1, and was increased to 5.35:1 in 1934. Production of this version ended after 1934, and the Standard used the 206.8 cubic inch engine thereafter. Second generation: 1937–1962 The Stovebolt engine was significantly re-engineered for the 1937 model year, distinguished from the earlier 1929-1936 engines by having a redesigned crankcase with four main bearings in lieu of the older engine's three bearings. It is often known as the "Blue Flame" engine, although that name was only officially applied beginning in 1953, and then only for the 235ci version coupled to the Powerglide automatic transmission (including in the Corvette). 216 This engine had a displacement with a bore and stroke of . A four-bearing crankshaft was added, along with 6.5:1 compression pistons, for . A new cylinder head in 1941 increased output to , and 6.6:1 compression gave the 1949 model . This generation did not use a fully pressurized oiling system. The connecting rods were oiled using an "oil trough" built into the oil pan that had spray nozzles that squirted a stream of oil at the connecting rods (which were equipped with "dippers"), thus supplying
