The Ferrari 412 P was a customer version of the 330 P3 race car, created for independent teams. Notably different from the factory models, these cars featured carbureted engines instead of Lucas fuel injection. Only two, chassis 0850 and 0854, were originally built as 412 Ps, while others like 0844 and 0848 were converted from P3 factory race cars. These modifications were intended to reduce power and prevent them from outperforming factory cars. All 412 Ps shared the P3's 4-liter engine block and chassis, built in 1966, with some delays due to labor strikes. The 412 P wasn't eligible for the 1968 International Championship of Makes, leading to Ferrari's temporary withdrawal from the championship. Today, surviving 412 P cars are valued at approximately $35–45 million USD.
