The Ferrari 250 GTO, known for its handbuilt production and various updates, exhibits notable differences between individual cars, especially in air intake and vent configurations. These modifications were often tailored to racing team needs or post-crash repairs. In 1964, the 250 GTO underwent a significant redesign by Mauro Forghieri and Mike Parkes, resulting in the Series II or GTO '64. This version incorporated aerodynamic elements from the 250LM, although it maintained its front-engine layout. Despite only marginal performance improvements, the GTO '64 still achieved racing success, including a win at the 1964 Daytona race with Phil Hill and Pedro Rodriguez driving for NART.
