Challenge Series build completed in 2017 after the partially finished car was stored by its original owner, American Iron Racing Series driver and constructor Ron McDuffie. It has been track-tested but never raced, with a 302ci Ford V8, Tremec T5 five-speed, three-link rear suspension, adjustable Bilstein coilovers, Baer brakes, and a Phoenix fire-suppression system. Annual mileage sits near the low end for this generation.
