Pretty cool.The LT5-powered ZR-1 broke a world record at the Firestone test track in Fort Stockton, Texas, when a team of drivers, led by Tommy Morrison, broke the 24-hour endurance mark by almost 15 mph, averaging 175.9 mph over 4,221 miles. Two years later, a ZR-1 took the checkered flag in the 24-hour World Challenge race in Canada, with another coming in second.
