1955 Porsche 356 Speedster Barn Find


The 1968 California pink slip shows this 1955 Porsche Speedster, California black plate # UPY304, registered on P34576 which was probably its original engine. Chassis #80413 is stamped in front of the gas tank, and on the tag attached to the left door post. According to research, it is speedster #212 of 1700.


VIN:     80413
Year: 1955
Make: Porsche
Model: 356
Body Type:     Convertible
Engine: Super 90
Number of Cylinders:     4
Transmission: 4 speed
Drive Type: RWD


The previous owners were likely the 2nd owners, purchasing it near Berkley, CA in September 1968. They drove it until 1974, and parked it when it developed some engine noises.  The 1960 S-90, 800409, that goes with the car was supposedly overhauled, but never installed.  The transmission is #36618.


#80413 is stamped into the panel below the gas tank and matches the same number on the left door post tag. Since the car had been parked since 1974 it didn’t show any outward signs of major collision damage. It most likely has all original moving panels.


Obviously, the S-90 engine is not correct for the car.
