Engine Options for the 1971 Corvette

In 1971, the Chevrolet Corvette offered a variety of power choices, with the most common being the small and big block V8 engines. Each variant came with its specific rating and characteristics, reflecting the advancements in automotive technology during that era.

The base engine for 1971 was a 350 cubic inch (5.7-liter) small block V8. This engine was carried over from the previous year with a few modifications to adapt to the new fuel types. The compression ratio was lowered to improve fuel tolerance in low and no-lead fuels. In 1970, this engine was rated at 270 horsepower. For the 1971 model, it was slightly upped to 300 horsepower.

Option: RPO LT-1 (454 ci/7.4 liter big block V8)

For those seeking higher performance, Chevrolet offered the LT-1 engine, which was a 454 cubic inch (7.4-liter) big block V8. Rated at 330 horsepower in 1971, this engine was also an improvement from the 370 horsepower seen in the 1970 model.

Option: RPO LS5 (454 ci/7.4 liter big block V8)

The LS5 engine was another variant of the big block V8, offering 365 horsepower in 1971. This was a significant decrease from the 390 horsepower seen in the 1970 model. The reduction in horsepower was due to the changes in fuel composition.

Special Edition: RPO LS6 (454 ci/7.4 liter big block V8 with aluminum heads)

The most powerful option available in 1971 was the LS6 engine, a variant of the big block V8 with aluminum heads. Designed for ultimate performance, this engine was expected to produce 425 horsepower. However, due to its rarity and the engineering challenges, it was rumored to be capable of over 500 horsepower. Only a small number of these engines were built, making them highly sought after by collectors.
