The first chevy inline 6 that cames to Brazil was the 230 engine in 1968. It survives only for 3 years. Then the 250 engine was introduced here, in Brazil, in 1971 and was produced untill 1992 and cames in a car called Chevrolet Opala. After that a car called Chevrolet Omega was introduced by GM to take the Opala´s place. In the begining the Omega cames with an Opel´s engine that was smaller than the 250. But the spare parts was so much expensive for most owners than GM decide to take back the good old 250 chevy engine. They only modified the head, making a 12 port intake, put a EFI and change a little the headers.
