Chevrolet 153 4-cylinder engine

The Chevrolet 153 was an overhead valve inline-four engine of 153 cubic inches, about 2.5 litres, designed in the early 1960s for the 1962 Chevy II. It was in effect the four-cylinder version of the Turbo-Thrift six, with a bore of 3 and 7/8 inches and a stroke of 3 and 1/4 inches, and it made 90 horsepower in its standard form. General Motors dropped it in North America after 1970 and replaced it with the Chevrolet 2300, but it lived on elsewhere: GM do Brasil used a 151 cubic inch redesign in the Opala until 1992, refitted to burn ethanol, General Motors South Africa built several sizes for a range of cars, and an Argentine 110 cubic inch version powered a locally built Opel. Descendants went into industrial and marine uses. It is a different engine from the Pontiac Iron Duke that came later, although the two are often confused.
