The Chevy 250 inline 6 cylinder engine was produced between 1966 and 1985 for the U.S. market. It was a reliable straightforward engine that came to fame mostly due to the fact that was offered alongside the Chevy 230 inline 6 in the all new Chevrolet Camaro. From 1974 to 1985 there was an integrated head produced for the 250 that offered a 1 barrel or 2 barrel carburetor variation. All 1 barrel integrated 250 inline 6 engines began with a casting number of 35, 37 or 1400. The 2 barrel variant has casting numbers that started with 36 or 1401. South America and Brazil in particular used the 250 inline 6 up until 1998 when it was finally discontinued.
