It's not unreasonable to say the Chevrolet small-block V-8 changed the face of automotive engine history. Innovative and technologically advanced when it debuted in 1955, it greatly influenced future V-8 engine designs, both inside General Motors and among the competition. Enthusiasts embraced it and an entire performance aftermarket sprang up around it. Over the years, variations of the small-block V-8 have been used in race cars, off-road trucks, boats, and even custom motorcycles.
