1967 was a banner year for the Enzo Ferrari motor company, as it saw the production of the mid-engined 330 P4, a renowned V12 endurance car meant to replace the previous year's P3. Only four Ferrari P4-engined cars were ever made: three new 330 P4s and one ex P3 chassis (0846). Their three-valve cylinder head was modeled after those of Italian Grand Prix-winning Formula One cars. To this was added the same fuel injection system from the P3 for an output of up to 450 hp (335 kW). The Ferrari P3 won the 1000 km Monza in 1966, and the P4 won the same race in 1967. Two P4s, and one 412 P electrified the racing world when they crossed the finish line together (in first 0846, second 0856, and third place 0844) in the 1967 24 Hours of Daytona, for a photo finish to counter Ford's photo of the Ford GT40 Mk.II crossing the finish line together First, Second, and Third at the 1966 24 Hours of Le Mans. Since then, the fate of these four nearly legendary cars has been the subject of much attention. All of the P4s built are accounted for.
There is no such thing as a P4 block. To save money Ferrari very cleverly cast blocks that could be built up as a 3L for F1, 3.3L for sports cars on tracks like Nürburgring and The Targa Florio where fuel consumption was very important because of the long laps. This was done in the same block by changing the piston skirt length, the crank journals size and the rod length.
The Super Chromes Ferrari P4 features a chrome-plated body and chassis, original Redline era style five-spoke wheels, bent-axle suspension, and a full-metal chassis — on this casting for the first time.
