This pic is Rod in the Zephyr Corvette, (reportedly fuel injected) at Renwick 1966.
If I understand correctly, the engine in the zephyr was out of the Tec-Mec, which was repowered with a Corvette engine from one of the Team Camoradi cars that was wrecked before it took the start at Le Mans in 1960. That being the case, was it Rochester Fuel injection ? Reportedly it was Bob Wallace that liberated the Corvette engine and gearbox, before giving the remains of the car to a Gendarme.
