Ferrari 330 P3

The evolution of the 330 P2 was the P3. It featured a new tubular chassis with a fiberglass drivers compartment tub. The engine and gearbox were an integral part of the structure, enhancing its rigidity as in previous versions. Compared to the power unit used on the P2, the V12 engine was almost 30 kg lighter thanks to redesigned cylinder heads, and a new Lucas injection system in place of the usual row of 6 Weber carburettors.

The car’s most important wins were racked up by Parkes/Scarfiotti at Spa and by Surtees/Parkes at the 1000 km of Monza.

Ferrari 330 P3 Valuation

The Ferrari 330 P3 is extremely rare and valuable, with only three chassis originally built in 1966—all for factory racing purposes. Due to its rarity, historical importance, and direct involvement in Ferrari’s works racing program (notably at Le Mans and Daytona), the 330 P3 is considered one of the crown jewels of Ferrari’s prototype lineage.

When such a car becomes available—which is exceedingly rare and often done privately—estimated values range from $20 million to over $30 million, depending on factors like:

  • Originality (e.g. unmodified chassis and bodywork)

  • Race history (factory entries at major events)

  • Provenance and ownership history

  • Restoration quality (if applicable)

Many 330 P3s were later converted into 330 P4 specifications, so unrestored, pure P3 examples are particularly valuable.
