The AMC 232 and 258 six-cylinder engines, produced by American Motors Corporation, were robust and reliable powerplants that found their way into a variety of vehicles. The 232 cubic inch (3.8 liter) engine, introduced in 1964, was a derivative of the earlier AMC 230. It offered a good balance of power and fuel economy, making it a popular choice for compact cars and light trucks. The 258 cubic inch (4.2 liter) engine, introduced in 1967, was a larger and more powerful version of the 232. With its increased displacement, it provided more torque and horsepower, making it suitable for larger vehicles and those requiring more hauling capacity. These engines were known for their simplicity and durability, with cast-iron blocks and heads that could withstand high levels of abuse. The AMC 232 and 258 engines were fitted in numerous AMC vehicles, including the Rambler, Javelin, Gremlin, Hornet, and Jeep CJ-5 and CJ-7. Their popularity extended beyond AMC itself, as they were also used in other manufacturers' vehicles, notably in International Harvester's Scout and some Ford models. These engines are highly regarded by enthusiasts for their straightforward design and robust construction. They are relatively easy to maintain and repair with readily available parts. The AMC 232 and 258 engines have developed a devoted following among off-roaders and enthusiasts who appreciate their ruggedness and ability to withstand demanding conditions. Their reputation for reliability and affordability, combined with their ease of modification, makes them a favorite choice for building high-performance or off-road vehicles.
