This 1989 Corvette is number 20 of approximately 30 cars prepared by Powell Development America for competition in the 1989 Corvette Challenge spec series. This example was reportedly driven by Al Lamb for all 12 races of the 1989 season, and is finished in a red, white, and blue #20 livery. Power comes from a 5.7-liter L98 V8 paired with a ZF six-speed manual transmission, and additional features include a roll cage, a fire suppression system, a driver-side window net, dual fixed-back bucket seats, side-exit exhaust outlets, Bilstein shocks, and 17” Dymag wheels.
