When we selected a Chevrolet Corvette ZR1 twin-cam, small-block 350 V-8 engine for our Cimtex Rods Super Cameo, we knew that we would be breaking new ground in the sense that GM never built a “production” automatic-transmission-equipped Corvette ZR1. However, there is record that a couple of Corvette ZR1s were specially equipped with automatic electronic overdrive transmissions for physically challenged Corvette enthusiasts. We don’t know whether it was done by the factory or by the private sector.
Nonetheless, it was our intent to run an automatic transmission behind this awesome powerplant. After all, we wanted our ’56 Super Cameo to be as civilized as possible, yet still be able to handle all the available torque and horsepower that will be the result of this twin Powerdyne (BD11-A) supercharged and intercooled Corvette ZR1 engine. But what type of GM automatic transmission would we actually be using?
