Darrell Waltrip outraced Bobby Allison to win the National 500 Grand National stock car race yesterday at Charlotte Motor Speedway.

Waltrip, starting from the pole and challenging throughout, took the lead for good 60 laps from the end. The 34-year-old driver from Franklin, Tenn., increased his lead over Allison in the Winston Cup rivalry to 58 points with three races remaining.

Waltrip has won three straight Grand National races. It was his 10th victory this season and sixth in the last 11 races. He has won three times on Charlotte's 1.5-mile, banked oval, but it was the first time he has won this race.

He drove his Buick Regal across the finish line 31.7 seconds ahead of Allison, who lost his last chance because of problems during a pit stop 16 laps from the end of the 334-lap race.

After rookie Tim Richmond, the only other competitor in the same lap with Waltrip and Allison at the time, blew his engine on the main straightaway, both the top cars made a final pit stop.

Waltrip's crew quickly gassed up and changed all four tires, but Allison's crew had trouble removing the right front tire. Allison lost a lap before he got his Buik back on the track.
