In the early 1960s, when factory racing was not technically supposed to exist under General Motors’ own corporate policy, a handful of very specific cars still rolled off assembly lines built almost entirely for the drag strip. This 1962 Chevrolet is one of them, and if you did not know to look for it, you would swear it was just another Impala. The debate over exactly what engine it is hiding still is not fully settled. Watch to see why even longtime owners disagree.
