New patent filings show how Maranello intends to keep twelve cylinders pure, yet legal.
Get lost in the magnificent sound of the Ferrari P4’s V-12
Ferrari only built four P4-spec race cars for 1967: three new chassis, and one based on the previous year’s 330 P3. That 1966 P3/4 is chassis 0846, driven by a very happy James Glickenhaus from time to time. There’s also the green P4 “0900” of David Piper, constructed in period in Italy with Enzo’s blessing, using Ferrari’s tubing and methods.
But when it comes to P4s out there, that’s it. Roughly five cars, only one of which remains completely original, or at least as much as a 1960s endurance prototype can be. Here are the two P4s I’ve seen in the metal so far, the Glickenhaus and the Piper cars:
This exclusivity brings us to this P4 by Norwood, one of the fifteen (so far) completed authentic replicas out of the planned 30, built in Texas according to the same methods as the ones in Maranello over half a century ago. Mecum Auctions estimates it to be worth up to $800,000 these days—and for good reason. These are such exact P4 replicas that they feature a hand-formed aluminum body shaped around a wooden buck, on a 4130 tubular steel chassis, with a Ferrari V-12 behind the driver.
Yet unlike the 443-horsepower fuel-injected 4.0-liter in the originals, the P4 by Norwood’s V-12 is a 5.75-liter Ferrari affair from the 575M Maranello, producing 508 horsepower at 7250 rpm, and 580 lb-ft at 5250 rpm. Add a five-speed stick shift with a limited-slip differential to that picture and be glad this car also comes with modern four-piston Wilwood brakes. The originals certainly didn’t, although they came with discs all around. However, one thing is for sure. The P4 by Norwood’s Tipo F133 V-12 has nothing to be ashamed of, no matter how close an original P4’s Colombo engine may be.
