However, it was the 350 cu in (5.7 L) series that became the best-known Chevrolet small-block. Installed in everything from station wagons and sports cars to commercial vehicles, boats, industrial equipment, and even (in highly modified form) in aircraft, the 350 is the most widely-used small-block engine of all time.
The 153 cu in engine had a 3 + 7 ⁄ 8-inch (98 mm) bore and 3 + 1 ⁄ 4-inch (82.6 mm) stroke, with two overhead valves per cylinder actuated by pushrods and a 1-3-4-2 firing order. The Chevy II's 194 cu in six-cylinder used a 3 + 9 ⁄ 16-inch (90.5 mm) bore, which by 1964 was enlarged to match the 153 four-cylinder's resulting in a ...
Dubbed EcoTec3, the 4.3 L (260 cu in) is a Generation V small block V6 truck engine. It gets its displacement from bore and stroke of 99.6 mm × 92 mm (3.921 in × 3.622 in) with a compression ratio of 11.0 to 1. Firing order is 1-6-5-4-3-2. [85] This engine replaces the unrelated 4.3L V6 whose lineage dates back to 1978.
These bore and stroke dimensions were later used by the 267 cu in (4.4 L) V8 Chevrolet engine. Also like the small block V8 engines, the 200 cu in (3.3 L) V6 used 2.45-inch (62.2 mm) main bearings and 2.1-inch (53.3 mm) rod bearing diameters. Being a 90° V6, Chevrolet took steps to eliminate the rough running tendencies of the 200.
This was so named because it began with Chevrolet's V8 engines.

For this inline-4 engine, 1-3-4-2 could be a valid firing order.. The firing order of an internal combustion engine is the sequence of ignition for the cylinders.. In a spark ignition (e.g. gasoline/petrol) engine, the firing order corresponds to the order in which the spark plugs are operated.
It was used in military 2 1 ⁄ 2-ton trucks with the Hydramatic transmission; however, the engine was a sealed engine for snorkel/submersion use, had an electric fuel pump, and other features such as a deep sump oil pan. From 1952 to 1959, GMC manufactured the civilian 302 engine, which was not sealed, had a mechanical fuel pump, and used a ...
The first number refers to the number of cylinders in the engine, followed by a hyphen or "V", indicating inline or vee cylinder block arrangements, respectively, then 53 for the Series designation, referring the nominal swept displacement per cylinder in cubic inches, rounding from 53.07 cu in (0.9 L) per cylinder. The basic engine code does ...
