That 1971 model is one sweet looking ride. What is the motor?
This rare beast is one of only 11 ever produced. Commonly thought of as the most desirable muscle car in the world, it is exceedingly unusual to see one of these for sale. This particular offering boasts of highly desirable features. These features include the 426 HEMI V8 engine with two four barrel carburetors, 727 automatic transmission, Super Track Pak package with DANA 60 rear end and 4.11 ratio gears, power convertible top, center console and more. This vehicle was built for Canadian export of which only two were built. In addition, it is finished in its factory correct In Violet (Plum Crazy) paint, making it the only 1971 HEMI ‘Cuda Convertible in this color.
