  • Acadian (automobile)


    1962 Acadian Invader and logoAcadian is a make of automobile produced by General Motors of Canada from 1962 to 1971. The Acadian was introduced so Canadian Pontiac-Buick dealers would have a compact model to sell, since the Pontiac Tempest was unavailable in Canada. Plans originally called for the Acadian to be based on the Chevrolet Corvair, which was produced at GM's Oshawa plant; however, the concept was moved to the Chevy II platform to be introduced for 1962. The brand was also offered in Chile, with models built in Arica.

  • Chevrolet 153 4-cylinder engine


    The 153-cubic-inch (2.5 L) 153 was an inline-four engine which was designed for use in the entry-level Chevy II/Nova. It is a four-cylinder version of the Chevrolet 230 inline-six. Usage of the 153 lasted through 1970 because of low demand (the motor was used as standard equipment with the Kaiser Jeep DJ-5A which was used by the United States Postal Service until 1971 where the 153 was replaced with the AMC inline six after Kaiser Jeep was purchased by American Motors), after which the inline-six was made the base powerplant with the Chevy II/Nova. Currently, descendants of the 153 are used with industrial (forklifts or generators) or marine applications. The 153 has a bore of and a stroke of . The firing order is 1-3-4-2. A later variant of the 153, the 181, used a larger bore and a longer stroke. The 181 (branded by GM as the Vortec 3000 for marine or industrial usage) was never installed in passenger cars in the United States (later variants of the Vortec 3000 had modified cylinder heads where machined bosses were drilled for use with multipoint fuel injection). The 153 engine is entirely different from the later Pontiac 151-cubic-inch (2.5 L) Iron Duke, but the two are often confused today.
