Base motor on the 1963 Riviera was the 401 cubic-inch Nailhead V8, so named for the unorthodox vertical position of its valves, which resembled large nails. The valves were tiny for an engine of its size, but helped produce lots of low-end power. With a 10.25-1 compression ratio and single 4-barrel carburetor, the 401 motor produced 445 ft-lbs of torque and 325 horsepower.
