The stroked 250 version produced 155 hp (116 kW) for Chevrolet and GMC. Between 1975 - 1984, an integrated cylinder head was produced, with one-barrel intakes for passenger cars, and two-barrel intakes for trucks after 1978.
During the mid-1970s, the Buick 231 and Chevrolet V6-90 (basically a variant of the Chevrolet small block V8) was replacing the Chevrolet 250 for use in passenger cars and light duty trucks/vans. Passenger car use of the 250-cubic-inch (4.1 L) engine was discontinued after the 1979 model year for North America (along with the Chevrolet 292) since the six was restricted to light truck usage (the 4.1 was discontinued after 1984 in North America where the Vortec 4.3 V6 became the base motor). Brazil held on to the 250 (Known as the 4.1 there) until 1998 for passenger cars when the Chevrolet Omega A was replaced by rebadged Australian Holdens. was held in Brazil for up to 2001 in Chevrolet Silverado when the line was extinct. It would be GM's final inline six until the introduction of the GM Atlas engine in late 2001.

[edit] 250-S
When the long duration races restarted in Brazil, in 1973, the Opala found a great competitor, the Ford Maverick, which was powered by an engine whose displacement was almost one liter bigger. It took Bob Sharp and Jan Balder, that gained a second place in the "24 Hours of Interlagos", in August of that year in an Opala, to pressure GMB to field on race tracks a more powerful engine.
By coincidence, engine development manager, Roberto B. Beccardi, was working on this engine hopping up project out of his own initiative, but he did lack impulse from factory and was not obtaining any approval. This impulse came right from these two pilots.
Thus, in July 1974 GM started to offer the 250-S engine as an option for the Opala 4100. It was slightly different from the version that would be launched two years later: the project of the motor was similar to that of the four cylinders units, did not get a vibration damper and the cooling fan came from the standard 2500, with four blades instead of six.
The Opala was now much faster than the Maverick GT and Ford did not waste time. It quickly homologated a version with four barrel carburetor,called "Quadrijet" in Brazil, and have no relationship with GM own Rochester Quadrajet carburator, found on various GM engines. In the racetracks, the accounting determinative factor for winning was pilots skill and pit organization on the track. The rivals walked side-by-side.
The 250-S has 171 Horsepower and 229.7 lb.-ft. at 2,400 rpm.
