Don't forget the '64s
This was the entry level model of the newly faced lifted line of 1964 Studebakers Still having its rubber floor mat and the Spartan use of chrome trim, this was the ideal candidate for a performance Studebaker.
The power train consisted of the same Studebaker 289 cubic-inch V8, with Paxton Supercharger, that powered various models of Studebakers to land speed records at the Bonneville Salt Flats in 1964. The transmission was a Borg Warner T-10 four-speed with a Dana 44 posi-traction axle, (Twin-Traction by Studebaker).
The suspension and brakes have been enhanced to accommodate the hard use of road racing. The challenger has performed trouble-free many times at Road Atlanta, competing in the Walter Mitty Challenge Series. It has been observed with a top speed of 135 MPH.
