Chapman led the first 19 laps chased by Magee, Trent Gossar, Rob Allman and Robbie Wyman.
On an Aerco Heating & Air Conditioning restart on Lap 20 Magee claimed the top spot with Chapman and Gossar close behind.
After taking the lead Chapman saw a comfortable margin disappear when he encountered a large pack of slower cars with Magee and Gossar right on his bumper when the caution flag waved on Lap 85 for a spin by Earl Adams II.
Chapman was able to maintain the lead on the final restart with Magee running several car lengths back to the finish.
Gossar finished third followed by Tommy Brown Jr., who made the trip from Louisville, and Allman.
In the Front Wheel Drive 100, it was a two-car shoot-out between Don Gallaher and Nick Warner over the final 25 laps with Gallaher entering the Tim Thompson Nationwide Insurance Winner’s Circle for the first time in 2013.
Warner led the first 40 laps before he got trapped by slower traffic which allowed Gallaher and Paul Phipps to slip inside coming off the fourth corner.
The three front-runners ran in a tight pack until Lap 75 when Warner used the high line to pass Phipps in Turn 3.
From that point, Gallaher and Warner pulled away followed by Phipps, Josh Tharp and Ron Phipps.
During the closing laps, Gallaher said he had to hold his car in gear to be able to hold off Warner.
“Last year, I ran this race and ended up with a torn up race car,” Gallaher said following the win. “I love racing at this track, the competition is tough. You can race here side by side and everyone races you clean.”
