It’s time once again for Throwback Thursday where we feature vintage photos of Corvettes. Last week, we featured one of Zora’s personal cars, the 1955/56 Corvette that was originally listed for sale for $3,500. Boy, if we only had a time machine for that sale!
For today TBT, we’re featuring a vintage photo and what we think is one of the more endearing pictures of Zora who was driving the EX87 Corvette we know today as Zora’s Mule.
It was back in December of 1955 – almost 60 years ago from today – that Zora first installed his signature “Duntov Cam” into the 1954 test Corvette called EX87 or EX87/5951, the 5951 being another engineering number that was assigned to the same car. The Corvette was then tested at GM’s Arizona Proving Grounds where it ran an astounding 163 mph!
Zora had increased the displacement of the regular 283 ci engine to 307 and with the new cam, was ready to take on the Daytona Speed Record. That same engine was pulled from EX87 and installed in a 1956 Corvette with the engineering number of 6901 and that car set a new record on the beaches of Daytona in January 1956 with a run of 150.583 mph.
One of the distinctive elements of the EX87 Mule was how Zora fabricated a special fiberglass headrest/tailfin for high speed stability. The car also had the regular windshield removed and in its place was a cut-down curved plexiglass windscreen. To help further the aerodynamics, a fiberglass tonneau covered the passenger side of the cockpit.
Today, Zora’s Mule resides in the Ken Lingenfelter collection where you can occasionally witness the car being started up or even taken for a spin. But sixty years ago almost to the date, EX87 became the Chevrolet’s first high performance Corvette.
Here’s the full size photo of Zora sitting in the EX87 Corvette Mule:
