The 1961 Impala SS ushered in the 409 engine. Known as the “W” Engine do to the unique shape of the valve covers, the 409 was introduced to help Chevrolet in NASCAR Competition. To be legal for competition Chevrolet was required to homologate a specific number of cars for consumer purchase. And any option that could help competition also had to be offered as a consumer option. The 1961 Impala was built on what was called the “X” Frame. It left little to no protection from side impacts, but was rigid and effective for racing competition. Henry had the “Dual-Quad” intake and carburetors installed, but they were not available until the 1962 model year. It was the Impala SS that inspired the Beach Boys song, “409”.

If you examine the body lines and rear facia of this 1961 Impala SS you will notice the influence from modern day jets and rocketry during this period. Automobile manufacturers took their cues from the influences of the day. Jets and Rockets were the biggest thing going at the time. Everyone had “Space Fever”! And, of course, chrome was the thing! The more chrome, the better!
