The 1955 Turbo-Fire V8 began Chevrolet’s famous small-block V8 family.
Chevrolet introduced the small-block V8 for the 1955 model year. Its compact dimensions, relatively low weight, and efficient design made it suitable for a wide range of passenger cars, performance models, and light trucks.
The engine was marketed as the Turbo-Fire V8 and initially displaced 265 cubic inches. It helped transform the performance of the Corvette, which had previously relied on a six-cylinder engine, and it became the foundation for decades of Chevrolet V8 development.
The name is sometimes confused with later Chevrolet big-block engines, including the Mark IV family, or with the Powerglide automatic transmission. Those are separate components and engine families. The original small-block’s architecture continued through many revisions and displacements, making it one of the most influential American V8 designs.
