NASCAR considering minor changes for Daytona

NASCAR will consider minor adjustments to reduce the possibility of engines overheating prior to the Daytona 500. But otherwise officials were pleased with the results of Saturday night's Budweiser Shootout, the first race since implementing changes to reduce tandem racing. Vice president of competition Robin Pemberton said before Sunday's qualifying for the 500 that complaints from teams about overheating were "moderate'' at best. He said changes could come in the form of opening up the front grill slightly to allow more air flow or adjusting the pressure release valve. Pemberton said NASCAR will re-evaluate later in the week with temperatures expected to be much warmer during Thursday's qualifying races and Sunday's 500 than it was during the Shootout held at night. "We said all along there was potential to make adjustments,'' Pemberton said. Pemberton said there are no plans to tell drivers they cannot bump draft in the corners or make adjustments in the spoiler height to provide more stability. There were three major wrecks of eight, six and nine cars in the Shootout. "The drivers know they can't push on the left rear end,'' Pemberton said. "They have to get acclimated.'' ESPN.com
