There is something original under the hood of this 1964 Chevrolet Impala SS, and it has low mileage.  

It is very rare and valuable to find a 1964 Chevrolet Impala SS.

If it has something original under the hood, it is even more valuable. The top-of-the-line Impala was the SS.

In 1964, the Impala was the best-selling car in the United States.

The Impala SS came with a range of V8 engines, from the 283 to the 409, but the 327 L76 is the most popular.

This engine was a solid-lifter, high-compression version of the 327. It had 365 hp and 350 lb-ft of torque.  

It was the same engine that the Corvette Sting Ray had too.
