Video: Watch the power of Earnhardt’s Chevy

Dale Earnhardt Jr. survived the longest rain delay in Daytona 500 history and a spate of accidents to score a hugely popular and emotional win at Daytona International Speedway Sunday night using a car that suspiciously appeared to have more power than anyone else as no one could catch up to his rear bumper even in the draft. His father's No. 3 was on pole and Dale Jr. wins the race. The PR NASCAR got out of Daytona can't be measured.
