Engine configurations in the 1971 Torino
Overview of 351C variants
The Torino offered two primary configurations of the 351 Cleveland in 1971, depending on carburetion and intake setup. The following figures reflect factory ratings typically cited for those configurations:
- 351C 4V (four-barrel carburetor): approximately 330 horsepower gross, with about 370 lb-ft of torque.
- 351C 2V (two-barrel carburetor): roughly 250–270 horsepower gross, with torque around 320–340 lb-ft.
These variants represent the higher-performance 4V option and the more modest 2V setup that accompanied different Torino trims and price points.
Why horsepower numbers vary and how they were measured
Measurement standards and practical notes
In 1971 Ford used gross horsepower ratings, which do not include the accessories and emissions systems that modern net ratings account for. As a result, the published numbers are higher than what you’d measure on an engine today once those components are factored in. Several factors can further affect observed power on a given car:
- Carburetor configuration (4V vs 2V) and intake manifold design
- Emission controls and exhaust setup
- Engine wear, tune, and fuel quality over time
- Transmission type and gearing that influence RPM range
For those restoring or authenticating a specific vehicle, checking the original build sheet, engine stamping, or VIN-based documentation is the best way to confirm exactamente which 351 Cleveland configuration it came with.
Summary
In short, a 1971 Torino with the 351 Cleveland 4V typically lists about 330 horsepower gross, while the 2V variant sits around 250–270 horsepower gross. These figures reflect era ratings and can differ from modern measurements; verify with factory documentation for a precise match to a particular car.
