oil to the rod bearings. Rod bearings were made of babbitt cast integral with the rod. The bearing was adjustable for wear by removing copper shims placed between the rod cap and connecting rod. In this way specified oil clearance could be maintained. This engine was also used in GM's British Bedford truck. In the late 1930s rival Austin decided to get into the 2-3 ton truck ("lorry") market and in a crash program based the design on the basic architecture of this "Stove Bolt" engine, except that they added detachable shell main and con-rod bearings and pressurized lubrication. That Austin engine, in six-cylinder form, post war known as the Austin D-Series, went on to power cars such as the Austin Sheerline and Princess, and the Jensen Interceptor and 541. Austin also lopped off two cylinders to create the BS1 engine and in that form various versions, with various capacities, powered cars such as the Austin 16, A70 Hampshire and Hereford, A90 Atlantic, the Austin-Healey 100-4 and the Austin Gipsy, a generation of commercial vans, as well as some models of the iconic London black taxi (FX3 and FX4). 235 In 1941 a version of the 216 engine was introduced for use in large trucks. Both the bore and stroke of ( were increased over the 216. This engine also had an oil "dipper system" as described above, in reference to the oiling system, as in the 216. The 235 was introduced to the Chevy passenger car line in 1950, coupled to the new Powerglide automatic transmission, and 3.55:1 rear differential. The new version used with the Powerglide transmission featured hydraulic lifters and larger intake valves to produce more power. The pushrod cover on the side of the engine also no longer extended across the cylinder head, to eliminate oil leaks. In 1953 the 235 engine became standard equipment in all Chevrolet passenger cars (except the sedan delivery body, which continued to use the older 216 until 1954), but when coupled to the standard three-speed manual transmission (called Thrift-King in that guise) it featured solid lifters and lower power output: versus with the Powerglide. A fully pressurized lubrication system with shell type main bearings in lieu of poured babbitt and aluminum pistons were also introduced in 1953, but only in the higher-output Blue Flame version in cars ordered with the Powerglide transmission. The alleged benefits of a "blue flame" rather
