Proof from Forghieri: Glickenhaus/Piper 0003 is NOT 0846.

[Elex]

Because I questioned whether Ferrari would have used the method found on the Glickenhaus/Piper 0003 chassis to deal with the issue of fitting the P4 engine to a P3 chassis, I wrote to Ing. Mauro Forghieri, who was the Chief Technical Director at Ferrari's Race Department from 1961 to 1984. As well as all the Formula 1 cars and other Prototypes from this period, he designed the 330 P3, 412P, 330 P3/4 (0846) and 330 P4. I included photos from Jim Glickenhaus's 0846 pdf document and asked whether or not the engine mountings were his work. Ing. Forghieri was kind enough to look over the photos and respond. I have his permission in writing to post his information, which has been independently authenticated on another web site, as follows:

"Dear Mr.Robertson

I will say what I remember of so old days.In 1966 we design the 330 P3-0846. This car take part at the 12 h of Sebring number 27 drivers Parkes Bondurant. I like to make clear that P3 and P4 are from aerodinamic point of view very close.The draft was done by the technical bureau of Ferrari racing DPT. MR Drogo had nothing to do with the cars of Ferrari racing departement. The 330 P3 spyder was modified at the end of 1966 in a new P4 with the new 3 valve engine,curved intakes with injection,new Ferrari gearbox, minor modifications to the chassis with 2400 wheelbase.The modest wheelbase was thanks to the good aereodinamic stability developed at the aereodinamic wind tunnel in Stutgart.

This prototipe was the test car for private test(first in Ferrari History) in Daytona December 1966. The 0846.P4 spyder was used in the following races 1967:
Daytona 24 h winner Amon-Bandini n.23
Targa Florio Vaccarella -Scarfiotti
Le Mans 67 Amon-Vaccarella
Amon was hit by a flying wheel and the car caught fire and was badly damaged. The car was discarted by Ferrari and the chassis was destroyed. The pictures,sended to me,show some solutions to accept the 330 P4 engine. The solutions tell me that probably another P3 chassis was used to have a new 0846 P4. Never the factory could accept the schowed solutions to bolt the chassis to the engine. At the factory was easier to modify in correct way the triangled-tube necessary to have a perfect engine mount. Your chassis is a P3 arranged by some body to accept the P4 engine and the correct wheelbase 2400.
I hope to have been of some help.

Kind regards
Mauro Forghieri"



From this response, we have learned that:

1. According to Mauro Forghieri, chassis 0846 was destroyed after Le Mans '67.
2. Mauro Forghieri did not engineer the engine mount modifications seen on the Glickenhaus chassis.
3. According to Mauro Forghieri, Ferrari never would have accepted such modifications.
4. According to Mauro Forghieri, the Glickenhaus chassis is not the original 0846.
5. According to Mauro Forghieri, the Glickenhaus chassis is probably another P3 chassis, modified to accept a P4 engine.

Of course, #5 creates another question: Which one and why? However, in corresponding with Ing. Forghieri I did not mention that the Glickenhaus chassis was a replica originally commissioned by David Piper. He only has photographs of the engine mountings so it is understandable why he concluded that it is probably another P3 chassis and not that of a replica of a P3/P4 that the chassis actually is.
