6 Of The Most Reliable Engines Ever Made By Chevrolet

Over the last 112 years, Chevrolet's lineup of production automobile engines has evolved. Chevrolet's first engine was the 40-horsepower 299-cubic-inch six-cylinder that powered the 1911 Chevrolet Classic Six. As Chevrolet's first production engine, the 299 propelled the Classic Six, a five-passenger touring sedan, from zero to 50 mph in 15 seconds and to a 65 mph top speed.

Chevrolet introduced its "bowtie" logo in 1914, along with its first four-cylinder engines. While the 1911–1914 Classic Six Chevrolets were too expensive for many people's budgets, the four-cylinder H-Series Royal Mail roadster and Baby Grand touring car models sold for less than half of the Classic Six price.

The 1914 Chevrolet four-cylinder was the first Chevy engine with intake and exhaust valves built into the cylinder heads. The early overhead-valve four-cylinder Chevrolet engine displaced 171 cubic inches and generated 24 horsepower. Chevrolet continued using the H-Series' four-cylinder design through 1928 due to its cost-effective reliability. 

Those were only the beginning. Over the next century, Chevrolet continued to build its reputation with reliable engines like these.

The Gen I 350-cubic-inch small-block V8

Introduced in 1955, the first generation Chevrolet small-block V8 became the foundation for engine variations that have powered Chevrolet vehicles for eight decades. While the 350-cubic-inch version wasn't the first, it's one of the most popular and reliable small-block V8 engines ever produced by Chevrolet.

The first Chevrolet small-block (SBC) 350 V8 debuted in the 1967 Camaro. Over the following years, Chevrolet installed the first-generation SBC 350 in a wide range of automobiles in its lineup, including sports cars, pickup trucks, family sedans, and SUVs. The Gen I SBC 350 found homes in various Chevrolet cars and trucks until 1992, when Chevrolet introduced the slightly revised Gen II LT1 350.

The 350 used the same small-block design and four-inch cylinder bores as the previous 327-cubic-inch V8, with a longer 3.48-inch crankshaft stroke compared to the 327's 3.25-inch stroke. Early carbureted versions gave way to throttle body injection after 1988, reducing cold morning starting issues. Considering its many years of service, Gear Head Engines calls it "one of the most reliable engines ever."
